Here, helical piers offered an elegant solution: lightweight installation equipment minimized ecological disruption while still providing robust support for the bridge's substructure. The success of this application underscores how helical pier technology aligns with sustainability goals by reducing carbon footprints during construction processes.


These case studies illustrate that helical piers are not only effective but also adaptable across various contexts-from residential housing developments threatened by shifting grounds to large-scale infrastructure projects navigating environmentally sensitive landscapes. Their ability to accommodate different loading scenarios makes them suitable candidates where traditional methods might falter or prove too costly.


In conclusion, exploring helical pier options unveils promising avenues toward addressing formidable soil challenges faced by engineers worldwide today; each example underlines how innovation meets practicality through strategic application tailored according specific needs encountered within respective environments thereby showcasing why they remain invaluable tools amongst modern foundational techniques employed industry-wide now more than ever before!

Helical piers, also known as screw piles or helical anchors, have emerged as a versatile and effective solution for addressing complex soil challenges in construction projects. These innovative foundation systems offer a host of advantages, particularly in situations where traditional foundation methods may fall short. By exploring several examples of projects where helical piers have successfully mitigated soil issues, we can appreciate their adaptability and reliability.


One notable example is their application in residential construction on sites with expansive clay soils. Traditional foundations often struggle to cope with the swelling and shrinking associated with these soils, leading to structural damage over time. Helical piers provide a robust alternative by anchoring structures below the active soil layer into more stable strata. This not only prevents future movement but also ensures long-term stability for homes built on challenging terrain.


In commercial construction, helical piers have demonstrated their utility in urban areas where space is limited and existing infrastructure must be preserved. For instance, when constructing additions or retrofitting old buildings, the use of helical piers minimizes disturbance to nearby structures while providing the necessary support for new loads. Their ability to be installed with minimal vibration and noise makes them ideal for densely populated areas where maintaining community harmony is paramount.


Infrastructure projects also benefit from the adaptability of helical piers. Consider roadways and bridges built over soft or unstable ground; traditional deep foundation methods can be costly and time-consuming. Helical piers offer a quicker solution that does not sacrifice strength or durability. Their modular design allows for easy installation even in remote or difficult-to-access locations, ensuring that essential transportation links are maintained without prolonged disruption.


Furthermore, environmental remediation projects often rely on helical pier solutions to stabilize contaminated sites before reclamation efforts begin. By securely anchoring containment structures or treatment systems in place, these projects can proceed safely without exacerbating existing soil instability issues.


In summary, the versatility of helical piers makes them an invaluable asset across a wide range of projects confronting unique soil challenges. Whether stabilizing homes on problematic clay soils, supporting urban developments amid dense infrastructure, reinforcing vital transport networks over uncertain terrain, or securing environmental remediation sites-helical piers consistently demonstrate their capacity to provide reliable foundational solutions where traditional methods might falter. As engineers continue to explore innovative approaches to geotechnical problems, it is clear that helical pier technology will remain at the forefront of sustainable construction practices well into the future.

The exploration of helical pier options for soil challenges is an intriguing subject that delves deep into the realm of geotechnical engineering.

This makes them an ideal choice for areas susceptible to seismic activity or heavy winds, ensuring structures remain steadfast even under challenging circumstances.


Moreover, the sustainability aspect of helical piers cannot be overlooked. As they require less concrete compared to traditional foundations, they contribute to lower carbon emissions during construction-a compelling advantage in today's era of heightened environmental consciousness.


In conclusion, exploring helical pier options presents substantial benefits both immediately upon implementation and over extended periods. The stability they provide addresses immediate safety concerns while their ease of installation offers economic advantages through reduced labor costs and faster project completion times. Additionally, their capacity to withstand diverse environmental pressures ensures enduring performance benefits that align with both structural needs and sustainability goals. As we advance further into an age where innovative solutions are crucial for overcoming complex engineering challenges, helical piers stand out as a formidable option worthy of consideration by industry professionals worldwide.

When considering construction projects, especially those dealing with challenging soil conditions, the choice of foundation systems can significantly impact both costs and economic benefits. Among the various options available, helical piers emerge as a compelling solution due to their versatility and efficiency. Evaluating cost considerations alongside economic benefits is crucial for understanding why these systems are increasingly favored in modern engineering.


Helical piers present an intriguing cost profile. Initially, the upfront costs for materials and installation might seem higher compared to traditional foundation methods like concrete footings. However, this perception shifts when considering the total expenditure over a project's lifetime. The installation of helical piers is typically faster and requires less labor than conventional methods, leading to reduced labor costs and quicker project completion times. This efficiency translates into lower overall expenses when accounting for time-sensitive factors such as rental equipment or project delays.


One of the standout economic benefits of helical piers is their adaptability to diverse soil conditions without extensive site preparation. In areas where soil stability poses significant challenges, traditional foundations may necessitate costly ground improvements or reinforcements. Helical piers mitigate these requirements due to their design; they screw into the ground using helically shaped plates that provide support through both end-bearing and skin friction mechanisms. This capability not only reduces preparatory work but also ensures robust performance in unstable soils, offering long-term durability that minimizes maintenance costs.


Moreover, helical piers offer considerable savings in terms of environmental impact-a factor that increasingly influences economic assessments in contemporary construction projects. Their installation produces minimal disturbance to the surrounding environment compared to more invasive techniques like pile driving or large-scale excavation required for other foundations. This reduced environmental footprint often aligns with regulatory incentives or reduces potential fines linked to ecological disruptions, adding another layer of financial benefit.


In addition to direct cost savings and environmental considerations, helical piers enhance property value by ensuring structural integrity even under adverse conditions. Properties built on stable foundations tend to retain their value better over time, providing a safeguard against depreciation related issues commonly associated with inadequate foundational solutions.


Furthermore, the predictability associated with helical pier installations contributes positively from an economic standpoint. Projects involving these systems often adhere more closely to budgetary forecasts because of fewer unforeseen complications during installation-a common pitfall with more traditional approaches in problematic soils.


In conclusion, while evaluating foundation options for challenging soil conditions can be complex, balancing cost considerations against potential economic benefits highlights why helical piers stand out as an attractive option. Their ability to reduce immediate expenditures through efficient installation processes while simultaneously offering long-term financial advantages through enhanced durability and reduced environmental impact makes them a worthy investment in modern construction endeavors dealing with difficult terrains.

When addressing the complex issue of soil challenges in construction, selecting the most effective foundation repair method is crucial. Among the various options available, helical pier installation stands out due to its unique benefits and cost-effectiveness compared to traditional methods like concrete piers or underpinning. Understanding these distinctions can significantly influence decision-making processes in both residential and commercial projects.


Helical piers, also known as screw piles, are a type of deep foundation solution that can be installed quickly with minimal disturbance to the surrounding environment. They consist of galvanized steel shafts with helix-shaped plates that are screwed into the ground using hydraulic machinery. This innovative approach offers several advantages over conventional methods.


Firstly, when comparing costs, helical piers often present a more economical option in terms of both direct and indirect expenses. The installation process is relatively swift and requires less labor than pouring concrete foundations or underpinning. This results in reduced labor costs and minimizes downtime for ongoing projects. Additionally, since helical piers can be installed in virtually any weather condition without waiting for materials like concrete to cure, project timelines are shortened further-translating into financial savings.


Another critical factor influencing cost considerations is the adaptability of helical piers to diverse soil conditions. Unlike traditional methods that may require extensive excavation or soil removal when dealing with challenging terrains such as expansive clay or loose gravel, helical piers can be directly installed into these soils without costly site preparation. This adaptability not only reduces material costs but also decreases the environmental impact associated with extensive excavation work.


Moreover, helical pier systems offer long-term durability that rivals traditional methods. Made from high-strength steel with corrosion-resistant coatings, they provide reliable support over time even in adverse soil conditions. This longevity translates into lower maintenance costs and fewer post-installation repairs-a significant consideration when evaluating overall expenses.


However, it's important to acknowledge situations where other repair methods might be more suitable despite higher initial costs. For instance, large-scale constructions requiring substantial load-bearing capacities might benefit more from deep concrete pilings depending on specific engineering assessments.


In conclusion, while each foundation repair method has its own merits based on context-specific needs, comparing their costs reveals compelling advantages for choosing helical pier installations under many circumstances involving challenging soils. Their economic efficiency stems from reduced labor demands during installation coupled with flexibility across varying geotechnical scenarios-all contributing positively towards maintaining budgetary constraints without compromising structural integrity or longevity.

When it comes to tackling soil challenges in construction, the choice of foundation can significantly influence not only the immediate success of a project but also its long-term economic viability. One promising option that has been gaining traction is the use of helical piers. Known for their durability and reliability, helical piers offer substantial long-term economic advantages that make them an attractive choice for builders and engineers alike.


Helical piers, also known as screw piles or anchors, are deep foundation solutions that are screwed into the ground using hydraulic machinery. Their design allows them to stabilize structures by reaching deeper, more stable soil layers, making them particularly effective in areas with poor soil conditions. This unique capability addresses one of the most pressing issues in construction: soil unpredictability.


One of the primary long-term economic benefits of helical piers is their durability. Made from high-grade steel, these piers are resistant to corrosion and environmental wear and tear, which ensures they maintain their integrity over time. This durability translates into fewer maintenance requirements and a longer lifespan compared to traditional foundation solutions like concrete footings or driven piles. For property owners and developers, this means reduced costs associated with repairs or replacements-financial savings that accumulate significantly over time.


Furthermore, the reliability of helical piers contributes to their economic appeal. Their installation process is less disruptive than other methods; it requires no excavation and generates minimal vibration and noise. This efficiency reduces labor costs and project timelines-an advantage that becomes especially pronounced in large-scale projects where minimizing delays is crucial for keeping budgets in check.


Another aspect where helical piers shine economically is their adaptability to different types of projects and environments. Whether it's a residential home on unstable clay or a commercial building on sandy soils near coastal areas, helical piers provide a tailored solution without necessitating major site modifications or specialized equipment beyond standard installation tools. This versatility reduces upfront costs associated with site preparation while ensuring structural safety-a dual benefit that enhances overall project value.


Importantly, choosing helical piers can also lead to long-term energy savings when used in tandem with sustainable building practices. As part of green construction strategies, they can support energy-efficient designs by facilitating better thermal insulation due to reduced heat loss through foundations-a factor that contributes indirectly but significantly to lower utility bills over a structure's lifespan.


In conclusion, exploring helical pier options presents compelling long-term economic advantages due to their exceptional durability and reliability. By reducing maintenance needs, cutting down initial installation costs through efficient processes, offering versatility across different terrains without sacrificing performance, and supporting sustainable practices that lead to energy savings-helical piers stand out as a cost-effective foundation solution for overcoming soil challenges in modern construction projects. As builders continue to seek reliable ways to ensure both structural integrity and financial prudence, helical piers offer a forward-thinking answer capable of meeting today's demands while securing future prosperity.

Helical piers, also known as screw piles or helical anchors, have emerged as an effective solution for addressing a variety of soil-related challenges in construction and infrastructure projects. Their design consists of steel shafts with helical plates that are screwed into the ground, providing a stable foundation in unstable or difficult soil conditions. This essay will explore the key points highlighting the effectiveness of helical piers in solving such issues.


One of the primary advantages of helical piers is their adaptability to different soil types and conditions. Traditional foundation solutions often struggle with soft or expansive soils, which can lead to uneven settling and structural damage over time. Helical piers are designed to reach deeper, more stable layers beneath problematic soil, effectively bypassing unstable surface conditions. This adaptability makes them suitable for a wide range of environments, including areas prone to flooding or seismic activity.


Another significant benefit of using helical piers is their installation speed and minimal site disruption. Compared to conventional methods like excavation and concrete pouring, installing helical piers requires less heavy equipment and labor. This process not only accelerates project timelines but also minimizes environmental impact by reducing soil displacement and preserving existing vegetation. Additionally, the installation can be performed in limited access areas where traditional methods would be impractical.


The load-bearing capacity of helical piers is another critical factor contributing to their effectiveness. These structures are engineered to support substantial loads by distributing weight evenly across multiple helices along the shaft. This capability ensures that buildings remain stable even when constructed on challenging terrain or under heavy use conditions. Furthermore, engineers can tailor the design of helical piers-by adjusting helix size, spacing, or shaft length-to meet specific load requirements for each project.


Cost-effectiveness is yet another compelling reason to consider helical piers for soil-related challenges. While initial material costs may vary depending on project specifications, reduced labor expenses and faster installation times often result in overall savings compared to traditional foundations. Moreover, because they require less maintenance over time due to their durability and stability, long-term costs associated with repairs or adjustments are minimized.


Finally, it is essential to note that helical piers offer an environmentally friendly option for addressing soil issues. Their installation generates minimal waste compared to other foundation methods that rely heavily on concrete production-a significant source of carbon emissions globally-and causes fewer disturbances within ecosystems surrounding construction sites.


In conclusion, exploring options involving helical piers presents numerous advantages when tackling complex soil challenges found throughout various construction projects worldwide: from adaptability across diverse terrains; rapid deployment minimizing site disruption; robust load-bearing capabilities ensuring lasting stability; cost-efficiency reducing both short-term expenditures & long-term maintenance needs-all while providing environmentally conscious alternatives benefiting our planet's ecosystems simultaneously-helically driven solutions continue proving themselves indispensable within modern engineering practices today!

As we delve into the future of foundation repair technologies, particularly in the realm of helical pier options for soil challenges, it's essential to acknowledge the ever-evolving landscape of engineering solutions designed to address structural stability. Helical piers have long been a go-to solution for stabilizing foundations in challenging soil conditions, thanks to their versatility and effectiveness. Looking ahead, several trends are poised to shape this field and further enhance the efficacy and application of helical piers.


Firstly, advancements in material science are expected to significantly impact helical pier technology. New materials that offer increased strength, durability, and corrosion resistance are being developed. These innovations could lead to piers that not only last longer but also perform better under extreme conditions. For instance, composite materials or advanced steel alloys might replace traditional steel piers, offering a more sustainable and efficient solution.


Another trend is the integration of smart technology into foundation repair systems. The concept of "smart piers" equipped with sensors that monitor structural health in real-time is gaining traction. Such systems could provide continuous data on load stresses and environmental conditions, allowing for predictive maintenance and reducing the risk of catastrophic failures. This proactive approach aligns with broader trends in building management where IoT devices play a crucial role.


Furthermore, customization and adaptability will become key features of future helical pier systems. As construction projects increasingly demand tailored solutions to meet specific site challenges, manufacturers are likely to offer modular pier designs that can be easily adjusted or expanded based on unique soil conditions or load requirements. This flexibility not only enhances performance but also reduces installation time and costs.


The use of advanced modeling software and simulation tools is another area where we anticipate significant progress. These technologies enable engineers to conduct comprehensive analyses of soil conditions before installation begins, ensuring optimal placement and design of helical piers. Improved accuracy in predicting how different soils will interact with foundation systems can lead to more reliable outcomes and fewer unexpected issues during construction.


Environmental considerations are also driving changes in foundation repair technologies. As sustainability becomes an integral part of engineering practices, there is a growing emphasis on minimizing the ecological footprint of construction activities. Future developments may include eco-friendly installation techniques that reduce ground disturbance or innovations aimed at enhancing the recyclability of piers once they've reached the end of their lifecycle.


In summary, as we explore helical pier options for addressing soil challenges in foundation repair, it is clear that technological advancements will play a pivotal role in shaping future trends. From novel materials and smart monitoring systems to adaptable designs and eco-conscious practices, these innovations promise not only improved performance but also greater reliability and sustainability in maintaining structural integrity amidst ever-changing environmental conditions.

Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement.[1][2] Removal of rock or soil as clastic sediment is referred to as physical or mechanical erosion; this contrasts with chemical erosion, where soil or rock material is removed from an area by dissolution.[3] Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres.

Agents of erosion include rainfall;[4] bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion proceeds the fastest on steeply sloping surfaces, and rates may also be sensitive to some climatically controlled properties including amounts of water supplied (e.g., by rain), storminess, wind speed, wave fetch, or atmospheric temperature (especially for some ice-related processes). Feedbacks are also possible between rates of erosion and the amount of eroded material that is already carried by, for example, a river or glacier.[5][6] The transport of eroded materials from their original location is followed by deposition, which is arrival and emplacement of material at a new location.[1]

While erosion is a natural process, human activities have increased by 10–40 times the rate at which soil erosion is occurring globally.[7] At agriculture sites in the Appalachian Mountains, intensive farming practices have caused erosion at up to 100 times the natural rate of erosion in the region.[8] Excessive (or accelerated) erosion causes both "on-site" and "off-site" problems. On-site impacts include decreases in agricultural productivity and (on natural landscapes) ecological collapse, both because of loss of the nutrient-rich upper soil layers. In some cases, this leads to desertification. Off-site effects include sedimentation of waterways and eutrophication of water bodies, as well as sediment-related damage to roads and houses. Water and wind erosion are the two primary causes of land degradation; combined, they are responsible for about 84% of the global extent of degraded land, making excessive erosion one of the most significant environmental problems worldwide.[9]: 2 [10]: 1 [11]

Intensive agriculture, deforestation, roads, anthropogenic climate change and urban sprawl are amongst the most significant human activities in regard to their effect on stimulating erosion.[12] However, there are many prevention and remediation practices that can curtail or limit erosion of vulnerable soils.

Physical processes

[edit]

Rainfall and surface runoff

[edit]
Soil and water being splashed by the impact of a single raindrop

Rainfall, and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion. Splash erosion is generally seen as the first and least severe stage in the soil erosion process, which is followed by sheet erosion, then rill erosion and finally gully erosion (the most severe of the four).[10]: 60–61 [13]

In splash erosion, the impact of a falling raindrop creates a small crater in the soil,[14] ejecting soil particles.[4] The distance these soil particles travel can be as much as 0.6 m (2.0 ft) vertically and 1.5 m (4.9 ft) horizontally on level ground.

If the soil is saturated, or if the rainfall rate is greater than the rate at which water can infiltrate into the soil, surface runoff occurs. If the runoff has sufficient flow energy, it will transport loosened soil particles (sediment) down the slope.[15] Sheet erosion is the transport of loosened soil particles by overland flow.[15]

A spoil tip covered in rills and gullies due to erosion processes caused by rainfall: Rummu, Estonia

Rill erosion refers to the development of small, ephemeral concentrated flow paths which function as both sediment source and sediment delivery systems for erosion on hillslopes. Generally, where water erosion rates on disturbed upland areas are greatest, rills are active. Flow depths in rills are typically of the order of a few centimetres (about an inch) or less and along-channel slopes may be quite steep. This means that rills exhibit hydraulic physics very different from water flowing through the deeper, wider channels of streams and rivers.[16]

Gully erosion occurs when runoff water accumulates and rapidly flows in narrow channels during or immediately after heavy rains or melting snow, removing soil to a considerable depth.[17][18][19] A gully is distinguished from a rill based on a critical cross-sectional area of at least one square foot, i.e. the size of a channel that can no longer be erased via normal tillage operations.[20]

Extreme gully erosion can progress to formation of badlands. These form under conditions of high relief on easily eroded bedrock in climates favorable to erosion. Conditions or disturbances that limit the growth of protective vegetation (rhexistasy) are a key element of badland formation.[21]

Rivers and streams

[edit]

Valley erosion is occurring due to the flow of the stream, and the boulders and stones (and much of the soil) that are lying on the stream's banks are glacial till that was left behind as ice age glaciers flowed over the terrain.

Valley or stream erosion occurs with continued water flow along a linear feature. The erosion is both downward, deepening the valley, and headward, extending the valley into the hillside, creating head cuts and steep banks. In the earliest stage of stream erosion, the erosive activity is dominantly vertical, the valleys have a typical V-shaped cross-section and the stream gradient is relatively steep. When some base level is reached, the erosive activity switches to lateral erosion, which widens the valley floor and creates a narrow floodplain. The stream gradient becomes nearly flat, and lateral deposition of sediments becomes important as the stream meanders across the valley floor. In all stages of stream erosion, by far the most erosion occurs during times of flood when more and faster-moving water is available to carry a larger sediment load. In such processes, it is not the water alone that erodes: suspended abrasive particles, pebbles, and boulders can also act erosively as they traverse a surface, in a process known as traction.[22]

Bank erosion is the wearing away of the banks of a stream or river. This is distinguished from changes on the bed of the watercourse, which is referred to as scour. Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times.[23]

Thermal erosion is the result of melting and weakening permafrost due to moving water.[24] It can occur both along rivers and at the coast. Rapid river channel migration observed in the Lena River of Siberia is due to thermal erosion, as these portions of the banks are composed of permafrost-cemented non-cohesive materials.[25] Much of this erosion occurs as the weakened banks fail in large slumps. Thermal erosion also affects the Arctic coast, where wave action and near-shore temperatures combine to undercut permafrost bluffs along the shoreline and cause them to fail. Annual erosion rates along a 100-kilometre (62-mile) segment of the Beaufort Sea shoreline averaged 5.6 metres (18 feet) per year from 1955 to 2002.[26]

Most river erosion happens nearer to the mouth of a river. On a river bend, the longest least sharp side has slower moving water. Here deposits build up. On the narrowest sharpest side of the bend, there is faster moving water so this side tends to erode away mostly.

Rapid erosion by a large river can remove enough sediments to produce a river anticline,[27] as isostatic rebound raises rock beds unburdened by erosion of overlying beds.

Coastal erosion

[edit]

Shoreline erosion, which occurs on both exposed and sheltered coasts, primarily occurs through the action of currents and waves but sea level (tidal) change can also play a role.

Sea-dune erosion at Talacre beach, Wales

Hydraulic action takes place when the air in a joint is suddenly compressed by a wave closing the entrance of the joint. This then cracks it. Wave pounding is when the sheer energy of the wave hitting the cliff or rock breaks pieces off. Abrasion or corrasion is caused by waves launching sea load at the cliff. It is the most effective and rapid form of shoreline erosion (not to be confused with corrosion). Corrosion is the dissolving of rock by carbonic acid in sea water.[28] Limestone cliffs are particularly vulnerable to this kind of erosion. Attrition is where particles/sea load carried by the waves are worn down as they hit each other and the cliffs. This then makes the material easier to wash away. The material ends up as shingle and sand. Another significant source of erosion, particularly on carbonate coastlines, is boring, scraping and grinding of organisms, a process termed bioerosion.[29]

Sediment is transported along the coast in the direction of the prevailing current (longshore drift). When the upcurrent supply of sediment is less than the amount being carried away, erosion occurs. When the upcurrent amount of sediment is greater, sand or gravel banks will tend to form as a result of deposition. These banks may slowly migrate along the coast in the direction of the longshore drift, alternately protecting and exposing parts of the coastline. Where there is a bend in the coastline, quite often a buildup of eroded material occurs forming a long narrow bank (a spit). Armoured beaches and submerged offshore sandbanks may also protect parts of a coastline from erosion. Over the years, as the shoals gradually shift, the erosion may be redirected to attack different parts of the shore.[30]

Erosion of a coastal surface, followed by a fall in sea level, can produce a distinctive landform called a raised beach.[31]

Chemical erosion

[edit]

Chemical erosion is the loss of matter in a landscape in the form of solutes. Chemical erosion is usually calculated from the solutes found in streams. Anders Rapp pioneered the study of chemical erosion in his work about Kärkevagge published in 1960.[32]

Formation of sinkholes and other features of karst topography is an example of extreme chemical erosion.[33]

Glaciers

[edit]
The Devil's Nest (Pirunpesä), the deepest ground erosion in Europe,[34] located in Jalasjärvi, Kurikka, Finland
Glacial moraines above Lake Louise, in Alberta, Canada

Glaciers erode predominantly by three different processes: abrasion/scouring, plucking, and ice thrusting. In an abrasion process, debris in the basal ice scrapes along the bed, polishing and gouging the underlying rocks, similar to sandpaper on wood. Scientists have shown that, in addition to the role of temperature played in valley-deepening, other glaciological processes, such as erosion also control cross-valley variations. In a homogeneous bedrock erosion pattern, curved channel cross-section beneath the ice is created. Though the glacier continues to incise vertically, the shape of the channel beneath the ice eventually remain constant, reaching a U-shaped parabolic steady-state shape as we now see in glaciated valleys. Scientists also provide a numerical estimate of the time required for the ultimate formation of a steady-shaped U-shaped valley—approximately 100,000 years. In a weak bedrock (containing material more erodible than the surrounding rocks) erosion pattern, on the contrary, the amount of over deepening is limited because ice velocities and erosion rates are reduced.[35]

Glaciers can also cause pieces of bedrock to crack off in the process of plucking. In ice thrusting, the glacier freezes to its bed, then as it surges forward, it moves large sheets of frozen sediment at the base along with the glacier. This method produced some of the many thousands of lake basins that dot the edge of the Canadian Shield. Differences in the height of mountain ranges are not only being the result tectonic forces, such as rock uplift, but also local climate variations. Scientists use global analysis of topography to show that glacial erosion controls the maximum height of mountains, as the relief between mountain peaks and the snow line are generally confined to altitudes less than 1500 m.[36] The erosion caused by glaciers worldwide erodes mountains so effectively that the term glacial buzzsaw has become widely used, which describes the limiting effect of glaciers on the height of mountain ranges.[37] As mountains grow higher, they generally allow for more glacial activity (especially in the accumulation zone above the glacial equilibrium line altitude),[38] which causes increased rates of erosion of the mountain, decreasing mass faster than isostatic rebound can add to the mountain.[39] This provides a good example of a negative feedback loop. Ongoing research is showing that while glaciers tend to decrease mountain size, in some areas, glaciers can actually reduce the rate of erosion, acting as a glacial armor.[37] Ice can not only erode mountains but also protect them from erosion. Depending on glacier regime, even steep alpine lands can be preserved through time with the help of ice. Scientists have proved this theory by sampling eight summits of northwestern Svalbard using Be10 and Al26, showing that northwestern Svalbard transformed from a glacier-erosion state under relatively mild glacial maxima temperature, to a glacier-armor state occupied by cold-based, protective ice during much colder glacial maxima temperatures as the Quaternary ice age progressed.[40]

These processes, combined with erosion and transport by the water network beneath the glacier, leave behind glacial landforms such as moraines, drumlins, ground moraine (till), glaciokarst, kames, kame deltas, moulins, and glacial erratics in their wake, typically at the terminus or during glacier retreat.[41]

The best-developed glacial valley morphology appears to be restricted to landscapes with low rock uplift rates (less than or equal to 2mm per year) and high relief, leading to long-turnover times. Where rock uplift rates exceed 2mm per year, glacial valley morphology has generally been significantly modified in postglacial time. Interplay of glacial erosion and tectonic forcing governs the morphologic impact of glaciations on active orogens, by both influencing their height, and by altering the patterns of erosion during subsequent glacial periods via a link between rock uplift and valley cross-sectional shape.[42]

Floods

At extremely high flows, kolks, or vortices are formed by large volumes of rapidly rushing water. Kolks cause extreme local erosion, plucking bedrock and creating pothole-type geographical features called rock-cut basins. Examples can be seen in the flood regions result from glacial Lake Missoula, which created the channeled scablands in the Columbia Basin region of eastern Washington.[43]

Wind erosion

[edit]
Árbol de Piedra, a rock formation in the Altiplano, Bolivia sculpted by wind erosion

Wind erosion is a major geomorphological force, especially in arid and semi-arid regions. It is also a major source of land degradation, evaporation, desertification, harmful airborne dust, and crop damage—especially after being increased far above natural rates by human activities such as deforestation, urbanization, and agriculture.[44][45]

Wind erosion is of two primary varieties: deflation, where the wind picks up and carries away loose particles; and abrasion, where surfaces are worn down as they are struck by airborne particles carried by wind. Deflation is divided into three categories: (1) surface creep, where larger, heavier particles slide or roll along the ground; (2) saltation, where particles are lifted a short height into the air, and bounce and saltate across the surface of the soil; and (3) suspension, where very small and light particles are lifted into the air by the wind, and are often carried for long distances. Saltation is responsible for the majority (50–70%) of wind erosion, followed by suspension (30–40%), and then surface creep (5–25%).[46]: 57 [47]

Wind erosion is much more severe in arid areas and during times of drought. For example, in the Great Plains, it is estimated that soil loss due to wind erosion can be as much as 6100 times greater in drought years than in wet years.[48]

Mass wasting

[edit]
A wadi in Makhtesh Ramon, Israel, showing gravity collapse erosion on its banks

Mass wasting or mass movement is the downward and outward movement of rock and sediments on a sloped surface, mainly due to the force of gravity.[49][50]

Mass wasting is an important part of the erosional process and is often the first stage in the breakdown and transport of weathered materials in mountainous areas.[51]: 93  It moves material from higher elevations to lower elevations where other eroding agents such as streams and glaciers can then pick up the material and move it to even lower elevations. Mass-wasting processes are always occurring continuously on all slopes; some mass-wasting processes act very slowly; others occur very suddenly, often with disastrous results. Any perceptible down-slope movement of rock or sediment is often referred to in general terms as a landslide. However, landslides can be classified in a much more detailed way that reflects the mechanisms responsible for the movement and the velocity at which the movement occurs. One of the visible topographical manifestations of a very slow form of such activity is a scree slope.[citation needed]

Slumping happens on steep hillsides, occurring along distinct fracture zones, often within materials like clay that, once released, may move quite rapidly downhill. They will often show a spoon-shaped isostatic depression, in which the material has begun to slide downhill. In some cases, the slump is caused by water beneath the slope weakening it. In many cases it is simply the result of poor engineering along highways where it is a regular occurrence.[52]

Surface creep is the slow movement of soil and rock debris by gravity which is usually not perceptible except through extended observation. However, the term can also describe the rolling of dislodged soil particles 0.5 to 1.0 mm (0.02 to 0.04 in) in diameter by wind along the soil surface.[53]

Submarine sediment gravity flows

[edit]

On the continental slope, erosion of the ocean floor to create channels and submarine canyons can result from the rapid downslope flow of sediment gravity flows, bodies of sediment-laden water that move rapidly downslope as turbidity currents. Where erosion by turbidity currents creates oversteepened slopes it can also trigger underwater landslides and debris flows. Turbidity currents can erode channels and canyons into substrates ranging from recently deposited unconsolidated sediments to hard crystalline bedrock.[54][55][56] Almost all continental slopes and deep ocean basins display such channels and canyons resulting from sediment gravity flows and submarine canyons act as conduits for the transfer of sediment from the continents and shallow marine environments to the deep sea.[57][58][59] Turbidites, which are the sedimentary deposits resulting from turbidity currents, comprise some of the thickest and largest sedimentary sequences on Earth, indicating that the associated erosional processes must also have played a prominent role in Earth's history.

Factors affecting erosion rates

[edit]

Climate

[edit]

The amount and intensity of precipitation is the main climatic factor governing soil erosion by water. The relationship is particularly strong if heavy rainfall occurs at times when, or in locations where, the soil's surface is not well protected by vegetation. This might be during periods when agricultural activities leave the soil bare, or in semi-arid regions where vegetation is naturally sparse. Wind erosion requires strong winds, particularly during times of drought when vegetation is sparse and soil is dry (and so is more erodible). Other climatic factors such as average temperature and temperature range may also affect erosion, via their effects on vegetation and soil properties. In general, given similar vegetation and ecosystems, areas with more precipitation (especially high-intensity rainfall), more wind, or more storms are expected to have more erosion.

In some areas of the world (e.g. the mid-western US), rainfall intensity is the primary determinant of erosivity (for a definition of erosivity check,[60]) with higher intensity rainfall generally resulting in more soil erosion by water. The size and velocity of rain drops is also an important factor. Larger and higher-velocity rain drops have greater kinetic energy, and thus their impact will displace soil particles by larger distances than smaller, slower-moving rain drops.[61]

In other regions of the world (e.g. western Europe), runoff and erosion result from relatively low intensities of stratiform rainfall falling onto the previously saturated soil. In such situations, rainfall amount rather than intensity is the main factor determining the severity of soil erosion by water.[17] According to the climate change projections, erosivity will increase significantly in Europe and soil erosion may increase by 13–22.5% by 2050 [62]

In Taiwan, where typhoon frequency increased significantly in the 21st century, a strong link has been drawn between the increase in storm frequency with an increase in sediment load in rivers and reservoirs, highlighting the impacts climate change can have on erosion.[63]

Vegetative cover

[edit]

Vegetation acts as an interface between the atmosphere and the soil. It increases the permeability of the soil to rainwater, thus decreasing runoff. It shelters the soil from winds, which results in decreased wind erosion, as well as advantageous changes in microclimate. The roots of the plants bind the soil together, and interweave with other roots, forming a more solid mass that is less susceptible to both water[64] and wind erosion. The removal of vegetation increases the rate of surface erosion.[65]

Topography

[edit]

The topography of the land determines the velocity at which surface runoff will flow, which in turn determines the erosivity of the runoff. Longer, steeper slopes (especially those without adequate vegetative cover) are more susceptible to very high rates of erosion during heavy rains than shorter, less steep slopes. Steeper terrain is also more prone to mudslides, landslides, and other forms of gravitational erosion processes.[61]: 28–30 [66][67]

Tectonics

[edit]

Tectonic processes control rates and distributions of erosion at the Earth's surface. If the tectonic action causes part of the Earth's surface (e.g., a mountain range) to be raised or lowered relative to surrounding areas, this must necessarily change the gradient of the land surface. Because erosion rates are almost always sensitive to the local slope (see above), this will change the rates of erosion in the uplifted area. Active tectonics also brings fresh, unweathered rock towards the surface, where it is exposed to the action of erosion.

However, erosion can also affect tectonic processes. The removal by erosion of large amounts of rock from a particular region, and its deposition elsewhere, can result in a lightening of the load on the lower crust and mantle. Because tectonic processes are driven by gradients in the stress field developed in the crust, this unloading can in turn cause tectonic or isostatic uplift in the region.[51]: 99 [68] In some cases, it has been hypothesised that these twin feedbacks can act to localize and enhance zones of very rapid exhumation of deep crustal rocks beneath places on the Earth's surface with extremely high erosion rates, for example, beneath the extremely steep terrain of Nanga Parbat in the western Himalayas. Such a place has been called a "tectonic aneurysm".[69]

Development

[edit]

Human land development, in forms including agricultural and urban development, is considered a significant factor in erosion and sediment transport, which aggravate food insecurity.[70] In Taiwan, increases in sediment load in the northern, central, and southern regions of the island can be tracked with the timeline of development for each region throughout the 20th century.[63] The intentional removal of soil and rock by humans is a form of erosion that has been named lisasion.[71]

Erosion at various scales

[edit]

Mountain ranges

[edit]

Mountain ranges take millions of years to erode to the degree they effectively cease to exist. Scholars Pitman and Golovchenko estimate that it takes probably more than 450 million years to erode a mountain mass similar to the Himalaya into an almost-flat peneplain if there are no significant sea-level changes.[72] Erosion of mountains massifs can create a pattern of equally high summits called summit accordance.[73] It has been argued that extension during post-orogenic collapse is a more effective mechanism of lowering the height of orogenic mountains than erosion.[74]

Examples of heavily eroded mountain ranges include the Timanides of Northern Russia. Erosion of this orogen has produced sediments that are now found in the East European Platform, including the Cambrian Sablya Formation near Lake Ladoga. Studies of these sediments indicate that it is likely that the erosion of the orogen began in the Cambrian and then intensified in the Ordovician.[75]

Soils

[edit]

If the erosion rate exceeds soil formation, erosion destroys the soil.[76] Lower rates of erosion can prevent the formation of soil features that take time to develop. Inceptisols develop on eroded landscapes that, if stable, would have supported the formation of more developed Alfisols.[77]

While erosion of soils is a natural process, human activities have increased by 10-40 times the rate at which erosion occurs globally. Excessive (or accelerated) erosion causes both "on-site" and "off-site" problems. On-site impacts include decreases in agricultural productivity and (on natural landscapes) ecological collapse, both because of loss of the nutrient-rich upper soil layers. In some cases, the eventual result is desertification. Off-site effects include sedimentation of waterways and eutrophication of water bodies, as well as sediment-related damage to roads and houses. Water and wind erosion are the two primary causes of land degradation; combined, they are responsible for about 84% of the global extent of degraded land, making excessive erosion one of the most significant environmental problems.[10][78]

Often in the United States, farmers cultivating highly erodible land must comply with a conservation plan to be eligible for agricultural assistance.[79]

A disaster inspector at work in the United States assessing tornado damage to a house

A home inspection is a limited, non-invasive examination of the condition of a home, often in connection with the sale of that home. Home inspections are usually conducted by a home inspector who has the training and certifications to perform such inspections. The inspector prepares and delivers to the client a written report of findings. In general, home inspectors recommend that potential purchasers join them during their onsite visits to provide context for the comments in their written reports. The client then uses the knowledge gained to make informed decisions about their pending real estate purchase. The home inspector describes the condition of the home at the time of inspection but does not guarantee future condition, efficiency, or life expectancy of systems or components.

Sometimes confused with a real estate appraiser, a home inspector determines the condition of a structure, whereas an appraiser determines the value of a property. In the United States, although not all states or municipalities regulate home inspectors, there are various professional associations for home inspectors that provide education, training, and networking opportunities. A professional home inspection is an examination of the current condition of a house. It is not an inspection to verify compliance with appropriate codes; building inspection is a term often used for building code compliance inspections in the United States. A similar but more complicated inspection of commercial buildings is a property condition assessment. Home inspections identify problems but building diagnostics identifies solutions to the found problems and their predicted outcomes. A property inspection is a detailed visual documentation of a property's structures, design, and fixtures. Property Inspection provides a buyer, renter, or other information consumer with valuable insight into the property's conditions prior to purchase. House-hunting can be a difficult task especially when you can't seem to find one that you like. The best way to get things done is to ensure that there is a property inspection before buying a property.

North America

[edit]

In Canada and the United States, a contract to purchase a house may include a contingency that the contract is not valid until the buyer, through a home inspector or other agents, has had an opportunity to verify the condition of the property. In many states and provinces, home inspectors are required to be licensed, but in some states, the profession is not regulated. Typical requirements for obtaining a license are the completion of an approved training course and/or a successful examination by the state's licensing board. Several states and provinces also require inspectors to periodically obtain continuing education credits in order to renew their licenses.[citation needed] Unless specifically advertised as part of the home inspection, items often needed to satisfy mortgage or tile requirements such as termite ("pest") inspections must be obtained separately from licensed and regulated companies.

In May 2001, Massachusetts became the first state to recognize the potential conflict of interest when real estate agents selling a home also refer or recommend the home inspector to the potential buyer.[citation needed] As a result, the real estate licensing law in Massachusetts was amended[1][non-primary source needed] to prohibit listing real estate agents from directly referring home inspectors. The law also prohibits listing agents from giving out a "short" name list of inspectors. The only list that can be given out is the complete list of all licensed home inspectors in the state.

Ancillary services such as inspections for wood destroying insects, radon testing, septic tank inspections, water quality, mold, (or excessive moisture which may lead to mold), and private well inspections are sometimes part of home inspector's services if duly qualified.

In many provinces and states, home inspection standards are developed and enforced by professional associations, such as, worldwide, the International Association of Certified Home Inspectors (InterNACHI); in the United States, the American Society of Home Inspectors (ASHI), and the National Association of Home Inspectors (NAHI)(No Longer active 10/2017); and, in Canada, the Canadian Association of Home and Property Inspectors (CAHPI), the Professional Home & Property Inspectors of Canada (PHPIC) and the National Home Inspector Certification Council (NHICC).

Currently, more than thirty U.S. states regulate the home inspection industry in some form.

Canada saw a deviation from this model when in 2016 an association-independent home inspection standard was completed. This was developed in partnership with industry professionals, consumer advocates, and technical experts, by the Canadian Standards Association. The CAN/CSA A770-16 Home Inspection Standard was funded by three provincial governments with the intent to be the unifying standard for home inspections carried out within Canada. It is the only home inspection standard that has been endorsed by the Standards Council of Canada.

In Canada, there are provincial associations which focus on provincial differences that affect their members and consumers. Ontario has the largest population of home inspectors which was estimated in 2013 as part of a government survey at being around 1500.[2]

To date, Ontario Association of Certified Home Inspectors is the only association which has mandated that its members migrate to the CAN/CSA A770-16 Home Inspection Standard, with a date of migration set as February 28, 2020. Other national and provincial associations have set it as an option to be added to other supported standards.

In Canada, only Alberta and British Columbia have implemented government regulation for the home inspection profession. The province of Ontario has proceeded through the process, with the passage of regulatory procedure culminating in the Home Inspection Act, 2017 to license Home Inspectors in that province. It has received royal assent but is still awaiting the development of regulations and proclamation to become law.

In Ontario, there are two provincial Associations, OAHI (the Ontario Association of Home Inspectors) and OntarioACHI (the Ontario Association of Certified Home Inspectors). Both claim to be the largest association in the province. OAHI, formed by a private member's Bill in the Provincial Assembly, has the right in law to award the R.H.I. (Registered Home Inspector) designation to anyone on its membership register. The R.H.I. designation, however, is a reserved designation, overseen by OAHI under the Ontario Association of Home Inspectors Act, 1994. This Act allows OAHI to award members who have passed and maintained strict criteria set out in their membership bylaws and who operate within Ontario. Similarly, OntarioACHI requires equally high standards for the award of their certification, the Canadian-Certified Home Inspector (CCHI) designation. To confuse things, Canadian Association of Home and Property Inspectors (CAHPI) own the copyright to the terms Registered Home Inspector and RHI. Outside of Ontario, OAHI Members cannot use the terms without being qualified by CAHPI.

The proclamation of the Home Inspection Act, 2017, requires the dissolution of the Ontario Association of Home Inspectors Act, 1994, which will remove the right to title in Ontario of the RHI at the same time removing consumer confusion about the criteria for its award across Canada.

United Kingdom

[edit]

A home inspector in the United Kingdom (or more precisely in England and Wales), was an inspector certified to carry out the Home Condition Reports that it was originally anticipated would be included in the Home Information Pack.

Home inspectors were required to complete the ABBE Diploma in Home Inspection to show they met the standards set out for NVQ/VRQ competency-based assessment (Level 4). The government had suggested that between 7,500 and 8,000 qualified and licensed home inspectors would be needed to meet the annual demand of nearly 2,000,000 Home Information Packs. In the event, many more than this entered training, resulting in a massive oversupply of potential inspectors.

With the cancellation of Home Information Packs by the coalition Government in 2010, the role of the home inspector in the United Kingdom became permanently redundant.

Inspections of the home, as part of a real estate transaction, are still generally carried out in the UK in the same manner as they had been for years before the Home Condition Report process. Home Inspections are more detailed than those currently offered in North America. They are generally performed by a chartered member of the Royal Institution of Chartered Surveyors.

India

[edit]

The concept of home inspection in India is in its infancy. There has been a proliferation of companies that have started offering the service, predominantly in Tier-1 cities such as Bangalore, Chennai, Kolkata, Pune, Mumbai, etc. To help bring about a broader understanding among the general public and market the concept, a few home inspection companies have come together and formed the Home Inspection Association of India.[3]

After RERA came into effect, the efficacy and potency of home inspection companies has increased tremendously. The majority of homeowners and potential home buyers do not know what home inspection is or that such a service exists.

The way that home inspection is different in India[4] than in North America or United Kingdom is the lack of a government authorised licensing authority. Apart from the fact that houses in India are predominantly built with kiln baked bricks, concrete blocks or even just concrete walls (predominantly in high rise apartments) this means the tests conducted are vastly different. Most home inspection companies conduct non-destructive testing of the property, in some cases based on customer requirement, tests that require core-cutting are also performed.

The majority of homeowners are not aware of the concept of home inspection in India. The other issue is that the balance of power is highly tilted toward the builder; this means the home buyers are stepping on their proverbial toes, because in most cases, the home is the single most expensive purchase in their lifetime, and the homeowners do not want to come across as antagonising the builders.

Home inspection standards and exclusions

[edit]

Some home inspectors and home inspection regulatory bodies maintain various standards related to the trade. Some inspection companies offer 90-day limited warranties to protect clients from unexpected mechanical and structural failures; otherwise, inspectors are not responsible for future failures.[a] A general inspection standard for buildings other than residential homes can be found at the National Academy of Building Inspection Engineers.

Many inspectors may also offer ancillary services such as inspecting pools, sprinkler systems, checking radon levels, and inspecting for wood-destroying organisms. The CAN/CSA-A770-16 standard allows this (in-fact it demands swimming pool safety inspections as a requirement) and also mandates that the inspector be properly qualified to offer these. Other standards are silent on this.

Types of inspections

[edit]

Home buyers and home sellers inspections

[edit]

Home inspections are often used by prospective purchasers of the house in question, in order to evaluate the condition of the house prior to the purchase. Similarly, a home seller can elect to have an inspection on their property and report the results of that inspection to the prospective buyer.

Foreclosure inspection

[edit]

Recently foreclosed properties may require home inspections.

Four point inspection

[edit]

An inspection of the house's roof, HVAC, and electrical and plumbing systems is often known as a "four-point inspection", which insurance companies may require as a condition for homeowner's insurance.

Disaster inspection

[edit]

Home inspections may occur after a disaster has struck the house. A disaster examination, unlike a standard house inspection, concentrates on damage rather than the quality of everything visible and accessible from the roof to the basement.

Inspectors go to people's homes or work places who have asked for FEMA disaster aid.

Section 8 inspection

[edit]

In the United States, the federal and state governments provide housing subsidies to low-income people through the Section 8 program. The government expects that the housing will be "fit for habitation" so a Section 8 inspection identifies compliance with HUD's Housing Quality Standards (HQS).

Pre-delivery inspection

[edit]

An inspection may occur in a purchased house prior to the deal's closure, in what is known as a "pre-delivery" inspection.

Structural inspection

[edit]

The house's structure may also be inspected. When performing a structural inspection, the inspector will look for a variety of distress indications that may result in repair or further evaluation recommendations.

In the state of New York, only a licensed professional engineer or a registered architect can render professional opinions as to the sufficiency structural elements of a home or building.[9] Municipal building officials can also make this determination, but they are not performing home inspections at the time they are rendering this opinion. Municipal officials are also not required to look out for the best interest of the buyer. Some other states may have similar provisions in their licensing laws. Someone who is not a licensed professional engineer or a registered architect can describe the condition of structural elements (cracked framing, sagged beams/roof, severe rot or insect damage, etc.), but are not permitted to render a professional opinion as to how the condition has affected the structural soundness of the building.

Various systems of the house, including plumbing and HVAC, may also be inspected.[10]

Thermal imaging Inspection

[edit]

A thermal imaging inspection using an infrared camera can provide inspectors with information on home energy loss, heat gain/loss through the exterior walls and roof, moisture leaks, and improper electrical system conditions that are typically not visible to the naked eye. Thermal imaging is not considered part of a General Home Inspection because it exceeds the scope of inspection Standards of Practice.

Pool and spa inspection

[edit]

Inspection of swimming pools and spas is not considered part of a General Home Inspection because their inspection exceeds the scope of inspection Standards of Practice. However, some home inspectors are also certified to inspect pools and spas and offer this as an ancillary service.[11]

Tree health inspection

[edit]

Inspection of trees on the property is not considered part of a General Home Inspection because their inspection exceeds the scope of inspection Standards of Practice. This type of inspection is typically performed by a Certified Arborist and assesses the safety and condition of the trees on a property before the sales agreement is executed.[12]

Property inspection report for immigration

[edit]

The UKVI (United Kingdom Visa and Immigration) issued guidance on the necessity of ensuring that properties must meet guidelines so that visa applicants can be housed in properties which meet environmental and health standards. Part X of the Housing Act 1985 provides the legislative grounding for the reports - primarily to ensure that a property is not currently overcrowded, that the inclusion of further individuals as a result of successful visa applications - whether spouse visa, dependent visa, indefinite leave to remain or visitor visa, can house the applicants without the property becoming overcrowded. Reports are typically prepared by environmental assessors or qualified solicitors in accordance with HHSRS (Housing Health and Safety Rating Scheme). Property inspection reports are typically standard and breakdown the legal requirements.

Pre-Listing Home Inspection

[edit]

A pre-listing inspection focuses on all major systems and components of the house including HVAC, electrical, plumbing, siding, doors, windows, roof and structure. It's a full home inspection for the seller to better understand the condition of their home prior to the buyer's own inspection.

It was a pleasure to work with Rick and his crew. From the beginning, Rick listened to my concerns and what I wished to accomplish. Out of the 6 contractors that quoted the project, Rick seemed the MOST willing to accommodate my wishes. His pricing was definitely more than fair as well. I had 10 push piers installed to stabilize and lift an addition of my house. The project commenced at the date that Rick had disclosed initially and it was completed within the same time period expected (based on Rick's original assessment). The crew was well informed, courteous, and hard working. They were not loud (even while equipment was being utilized) and were well spoken. My neighbors were very impressed on how polite they were when they entered / exited my property (saying hello or good morning each day when they crossed paths). You can tell they care about the customer concerns. They ensured that the property would be put back as clean as possible by placing MANY sheets of plywood down prior to excavating. They compacted the dirt back in the holes extremely well to avoid large stock piles of soils. All the while, the main office was calling me to discuss updates and expectations of completion. They provided waivers of lien, certificates of insurance, properly acquired permits, and JULIE locates. From a construction background, I can tell you that I did not see any flaws in the way they operated and this an extremely professional company. The pictures attached show the push piers added to the foundation (pictures 1, 2 & 3), the amount of excavation (picture 4), and the restoration after dirt was placed back in the pits and compacted (pictures 5, 6 & 7). Please notice that they also sealed two large cracks and steel plated these cracks from expanding further (which you can see under my sliding glass door). I, as well as my wife, are extremely happy that we chose United Structural Systems for our contractor. I would happily tell any of my friends and family to use this contractor should the opportunity arise!

The staff was helpful, very nice and easy to work with and completed the work timely and cleaned up well. Communications faltered a bit at times and there was an email communications glitch which was no fault of anyone, but no big deal and all ended up fine. We sure feel better to have this done and hope that is the end of our structural issues. It does seem like (after talking to several related companies), that it would be great if some of these related companies had a structural engineer on staff vs using on the job expertise gained over years - which is definitely valuable! But leaves a bit of uncertainty - and probably saves money for both sides may be the trade-off? So far, so good though! Thank you.

What a fantastic experience! Owner Rick Thomas is a trustworthy professional. Nick and the crew are hard working, knowledgeable and experienced. I interviewed every company in the area, big and small. A homeowner never wants to hear that they have foundation issues. Out of every company, I trusted USS the most, and it paid off in the end. Highly recommend.

USS was excellent. They are honest, straightforward, trustworthy, and conscientious. They thoughtfully removed the flowers and flower bulbs to dig where they needed in the yard, replanted said flowers and spread the extra dirt to fill in an area of the yard. We've had other services from different companies and our yard was really a mess after. They kept the job site meticulously clean. The crew was on time and friendly. I'd recommend them any day! Thanks to Jessie and crew.

USS did an amazing job on my underpinning on my house, they were also very courteous to the proximity of my property line next to my neighbor. They kept things in order with all the dirt/mud they had to excavate. They were done exactly in the timeframe they indicated, and the contract was very details oriented with drawings of what would be done. Only thing that would have been nice, is they left my concrete a little muddy with boot prints but again, all-in-all a great job

Frequently Asked Questions

Helical piers are steel shafts with helical plates that are screwed into the ground to provide support for structures. They work by transferring the load of a building from unstable or weak soil layers near the surface to more stable, deeper soil or bedrock, thus stabilizing the foundation and preventing further cracking.
A professional structural engineer or foundation specialist should assess your site conditions through soil testing and an evaluation of your foundations current state. They will consider factors such as soil type, moisture levels, and depth of stable strata to determine if helical piers are appropriate for stabilizing your foundation.
Helical piers offer several advantages including quick installation with minimal excavation, suitability for various soil types, immediate load-bearing capacity after installation, long-term stability solutions for shifting soils, and they cause less disruption compared to traditional underpinning methods.
