Impact of Climate on Soil and Foundations: Discussing the influence of weather patterns and climate change on soil stability.

Hairline fractures in foundation walls are subtle yet significant indicators of potential structural issues in a home. Recognizing these early signs can help prevent more serious damage and costly repairs in the future. Understanding the causes behind these fractures is essential for homeowners, builders, and inspectors alike.


Foundation walls play a critical role in supporting the weight of a building and maintaining its structural integrity. However, they are subject to various stresses that can lead to hairline fractures over time. One common cause of these minor cracks is soil movement around the foundation. Soil naturally expands when wet and contracts when dry, creating pressure on foundation walls. This cyclical stress can slowly lead to small cracks as the walls adjust to the shifting soil.


Another contributing factor is poor drainage around the foundation. When water accumulates near the base of a house due to inadequate drainage systems or clogged gutters, it increases hydrostatic pressure on the walls. Over time, this added pressure can result in hairline fractures as the foundation attempts to manage the excess load.


Temperature fluctuations also play a significant role in causing hairline fractures. As temperatures rise and fall with changing seasons, materials like concrete expand and contract. This thermal movement can create tension within the foundation walls, potentially leading to small cracks forming over time as the materials settle back into place.


Construction practices during building also have an impact on whether or not hairline fractures may develop later on. If substandard materials were used or if proper curing times were not observed during construction, foundations might be more susceptible to cracking under normal environmental stresses.


Lastly, seismic activity can contribute to hairline fractures even in areas not commonly associated with earthquakes.

Understanding the common factors that contribute to these fractures can empower homeowners to take preventative measures and seek timely repairs.


One of the primary factors leading to hairline fractures in basement walls is soil movement. The earth surrounding a home's foundation is in a constant state of flux due to changes in moisture levels and temperature variations. During heavy rains or melting snow, soil can become saturated with water, causing it to expand and exert pressure on basement walls. Conversely, during dry spells, the soil contracts, reducing its support for the foundation. This continuous cycle of expansion and contraction creates stress on basement walls, leading to the formation of hairline fractures.


Another significant factor is poor construction practices or materials used during the building phase. If the concrete used for the foundation lacks proper curing or reinforcement, it becomes susceptible to cracking under pressure. Additionally, inadequate drainage systems around a home's foundation can exacerbate this issue by allowing water to accumulate and increase hydrostatic pressure against the walls.


Natural settling of a house over time also contributes to hairline fractures. As buildings age, they naturally settle into their foundations due to gravity and other environmental forces. This settling process can cause slight shifts in alignment and load distribution across basement walls, resulting in small cracks.


Temperature changes play a pivotal role as well. Concrete expands when exposed to heat and contracts when cooled. In regions with extreme temperature fluctuations between seasons, these thermal movements can cause stress on concrete structures like basement walls, leading to fracture development over time.


Lastly, vibrations from external sources such as nearby construction work or heavy traffic can impact basement wall integrity significantly. These vibrations create additional dynamic loads on already stressed structures which could accelerate crack formation.


In conclusion, recognizing early hairline fractures involves understanding various contributing factors ranging from soil dynamics and construction quality to natural settling processes and environmental conditions like temperature changes and external vibrations.

Epoxy injections are particularly favored because they not only restore structural integrity but also prevent water leakage-a critical factor in basements prone to moisture issues.


Another effective approach is using polyurethane injections. Similar to epoxy repairs, polyurethane is injected into cracks; however, this material is highly flexible compared to epoxy and is better suited for environments where there might be ongoing movement or vibration. Its flexibility allows it to expand and contract with minor shifts in the structure without compromising its sealing capabilities.


In cases where aesthetic appearance is a priority alongside functionality-perhaps in finished basements-a surface sealant might be employed after initial crack filling. These sealants are usually applied over repaired areas to provide a smooth finish that blends with surrounding materials while adding an additional layer of protection against moisture ingress.


For those who prefer a more hands-on DIY approach or when dealing with very minor cracks, patching compounds like hydraulic cement could be used. Hydraulic cement expands as it cures and creates a tight seal within cracks up to half an inch wide. It's a cost-effective solution that provides immediate results; however, it's generally best suited for non-structural repairs due to its limited bonding strength compared to professional-grade materials like epoxy or polyurethane.


While these methods are commonly used for repairing hairline fractures in basement walls, it's essential to consult with professionals when dealing with persistent or extensive cracking issues. Structural engineers can assess whether underlying problems-such as foundational movement-require more comprehensive interventions beyond simple crack repair.


In conclusion, recognizing and repairing hairline fractures promptly can prevent larger structural issues down the line. Homeowners should familiarize themselves with both signs of damage and common repair techniques like epoxy and polyurethane injections or hydraulic cement applications. By doing so, they can ensure their homes remain safe havens built on strong foundations free from undue stress caused by unchecked cracks in basement walls.

When it comes to recognizing early hairline fractures in basement walls, choosing the appropriate repair strategy is crucial not only for maintaining the structural integrity of a building but also for preventing more serious problems down the line. Each repair approach carries its own set of advantages and disadvantages, making it imperative to weigh these factors carefully before proceeding.


One common repair strategy involves using epoxy injections to fill the cracks. This method is particularly effective for non-moving hairline fractures, as epoxy can seep deep into the crevices and hardens into a solid seal. The primary advantage of this technique is its ability to restore the original strength of the wall by binding the crack sides together. However, it does have its downsides. Epoxy repairs can be costly and require professional application, which might not be feasible for all homeowners. Additionally, if there are underlying issues causing movement or moisture infiltration in the basement wall, an epoxy injection alone may not address these foundational problems.


Another popular option is using polyurethane foam injections. Unlike epoxy, polyurethane foam is more flexible and can adapt to slight wall movements without cracking again. This makes it ideal for dynamic environments where slight shifting might occur due to temperature changes or minor ground movements. The flexibility of polyurethane offers a significant pro; however, its strength isn't comparable to that of epoxy, making it unsuitable for structural reinforcement purposes.


Beyond injections, applying surface sealants like waterproof coatings can serve as a preventive measure against water penetration through hairline cracks. These coatings are relatively easy to apply and cost-effective compared to other methods. On the downside, surface sealants often act as temporary solutions that don't tackle potential underlying issues like hydrostatic pressure or soil erosion outside the foundation walls.


For those dealing with more severe causes behind hairline fractures, opting for underpinning techniques such as helical piers or steel push piers could be beneficial. These methods involve reinforcing the foundation itself rather than just addressing visible cracks on walls. Underpinning offers a long-term solution by stabilizing shifting foundations; however, it's invasive and requires considerable financial investment and expert handling.


Choosing between these repair strategies should ideally begin with accurately diagnosing why those hairline fractures appeared in your basement walls initially-whether due to settling soil conditions beneath your home's foundation or poor drainage systems surrounding your property-and targeting those root causes directly alongside any chosen physical repair method will ensure lasting results while minimizing future risks associated with neglected maintenance requirements over time!

When it comes to maintaining the integrity of a home, few things are as crucial as the stability of its foundation. Basement walls play a pivotal role in supporting the structure above, and any compromise here can lead to significant issues. One subtle yet potentially serious problem that homeowners often overlook is the presence of hairline fractures in basement walls. Recognizing these early and seeking professional evaluation and repair solutions is essential for preventing more extensive damage.


Hairline fractures may seem innocuous at first glance. They are typically small, thin cracks that might appear harmless. However, they can be indicative of underlying issues such as settling foundations, hydrostatic pressure from groundwater, or even poor construction practices. If not addressed promptly, these minor fissures can widen over time, leading to water infiltration, increased structural stress, and ultimately, costly repairs.


The importance of professional evaluation in this context cannot be overstated. While some homeowners might feel tempted to address these issues themselves with DIY solutions available on the market, doing so could lead to inadequate repairs that merely mask symptoms rather than addressing root causes. A professional evaluation involves a comprehensive assessment by experts who understand the intricacies of structural engineering and geology. These professionals have the tools and expertise needed to accurately diagnose the severity and potential causes of fractures.


Once an evaluation has been conducted, it becomes much easier to devise an effective repair strategy tailored to the specific needs of the home. Professional repair solutions go beyond superficial fixes; they aim to restore and reinforce structural integrity for long-term safety and durability. Techniques such as epoxy injections can seal cracks effectively while carbon fiber reinforcements provide additional support where necessary.


Moreover, engaging with professionals ensures compliance with local building codes and standards-a critical factor when considering property value and future resale prospects. In many cases, homes with documented professional repairs command higher buyer confidence compared to those with undocumented DIY attempts.


In conclusion, while hairline fractures in basement walls may initially appear trivial, their potential implications for a home's structural health are anything but minor. By prioritizing professional evaluation and repair solutions at the earliest signs of trouble, homeowners can safeguard their investment while ensuring peace of mind knowing that their foundation remains strong and secure against time's relentless pressures and environmental factors alike.

In the realm of residential construction and maintenance, the structural integrity of a building is paramount. Basement walls play a critical role in supporting the overall structure, and any compromise in their stability can lead to significant safety concerns. One of the subtle yet potentially serious issues that homeowners might face is hairline fractures in these walls. Recognizing these early signs of damage can be tricky, yet it is crucial for preventing further deterioration. This is where the role of experts becomes indispensable.


Experts, such as structural engineers and experienced contractors, bring a wealth of knowledge and specialized skills to the table when assessing damage severity in basement walls. Their expertise allows them to distinguish between superficial cracks that might occur due to minor settling or temperature fluctuations, and those indicative of more severe underlying problems like foundation movement or hydrostatic pressure.


A key aspect of an expert's role is conducting thorough inspections using advanced tools and techniques that go beyond what an untrained eye can perceive. For instance, they might use moisture meters to detect hidden water infiltration, or employ digital crack monitors to track changes over time. These methods provide valuable data that help in accurately diagnosing the extent of damage.


Furthermore, experts are equipped with an understanding of building codes and industry standards, which enables them to advise on necessary repairs or reinforcements while ensuring compliance with safety regulations. They can propose tailored solutions based on the specific conditions observed during their assessment-whether it's recommending waterproofing measures or suggesting underpinning techniques for more serious foundation issues.


Beyond technical assessments, experts also play a pivotal advisory role by educating homeowners about potential risks associated with hairline fractures if left unattended. They emphasize preventive maintenance strategies to mitigate future damage, thereby extending the lifespan of basement walls and enhancing overall property value.


In essence, while recognizing early hairline fractures in basement walls might initially seem like a manageable task for homeowners armed with basic DIY knowledge, relying on expert evaluation ensures accuracy and peace of mind. The nuanced understanding these professionals offer not only aids in addressing immediate concerns but also fosters long-term structural resilience. Thus, involving experts at the earliest sign of trouble serves as a prudent investment in safeguarding one's home against unforeseen challenges.

When it comes to maintaining the structural integrity of a home, few issues are as disconcerting as discovering hairline fractures in basement walls. These seemingly minor cracks can be harbingers of more significant problems if not addressed promptly and appropriately. Homeowners often face the decision between handling these repairs themselves or enlisting professional repair services. While the DIY approach might seem tempting due to perceived cost savings and convenience, opting for professional repair services offers numerous benefits that far outweigh the initial expense.


The first and foremost advantage of hiring professional repair services is their expertise and experience. Professionals possess specialized knowledge about the myriad factors that contribute to basement wall fractures, such as soil pressure, water infiltration, or structural movement. This expertise allows them to accurately diagnose the root cause of the problem rather than merely addressing superficial symptoms. In contrast, a DIY approach may lead to misdiagnosis or incomplete repairs, which could exacerbate the issue over time.


Furthermore, professional repair services have access to advanced tools and materials that are often unavailable or too costly for individual homeowners. These tools enable them to perform high-quality repairs efficiently and effectively. For instance, professionals might use industry-grade sealants and reinforcements that provide long-lasting solutions against future cracking. Attempting similar repairs with standard consumer products may not deliver comparable results, potentially leading to recurring issues.


Safety is another critical area where professional services shine compared to DIY efforts. Repairing basement walls can involve working in confined spaces with heavy materials or hazardous substances like epoxy resins. Professionals are trained in safety protocols and equipped with protective gear, reducing the risk of injury during the repair process. Homeowners attempting these tasks without proper training may inadvertently put themselves at risk.


Moreover, many professional repair companies offer warranties on their work, providing homeowners with peace of mind that their investment is protected should any issues arise post-repair. Such guarantees are generally absent from DIY projects, leaving homeowners vulnerable if their initial fixes prove insufficient over time.


Finally, engaging professional services saves homeowners valuable time-time that can be better spent on personal pursuits rather than labor-intensive home repairs. Professionals typically complete projects faster due to their experience and efficiency, minimizing disruption to daily life.


In conclusion, while tackling basement wall fractures independently might appeal as a cost-saving measure initially, the benefits of hiring professional repair services make them a superior choice for most homeowners. From expert diagnosis and quality workmanship to enhanced safety measures and warranties on completed work-the advantages are manifold. By investing in professional repairs early on when hairline fractures first appear, homeowners can safeguard their property's structural integrity and ensure long-term peace of mind.

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]

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]
Bathymetry of submarine canyons in the continental slope off the coast of New York and New Jersey

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]

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!

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.

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.

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

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.

Frequently Asked Questions

Common signs include small, thin cracks often less than 1/16 inch wide, slight water seepage or dampness around the crack, minor flaking or peeling of paint near the fracture, and subtle shifts or unevenness in the wall surface.
Harmless hairline fractures are typically narrow, stable over time, and not accompanied by other structural issues. Fractures needing attention may widen over time, appear alongside other cracks, show signs of water leakage or mold growth, or cause noticeable wall movement.
Use a crack monitoring gauge to track any widening over time. You can also take regular photographs with date stamps for visual comparison. For precise measurement, a micrometer can help assess changes in crack width.
Consult a professional if you notice any significant widening of the cracks, persistent moisture problems, additional cracking elsewhere in your foundation, visible bowing or bulging of walls, or if youve monitored changes indicating worsening conditions.
