Understanding what is happening in the ground beneath a building or other structure, including the type of foundation it is built on, can be key to identifying the cause of settlement and potential solutions. This is especially important for private, commercial, and municipal owners in areas known for unstable soils. Homes built on loose soils, old landfills, sand, and expansive clays are particularly vulnerable to seasonal or extreme weather conditions, droughts, and floods. Historical mining activity can also affect soil properties in certain areas.
Structural problems often arise from varying moisture levels in clay foundations, whose layers can shrink, crack, or shift in hot weather and then expand during wetter or colder seasons. Other issues can result from tree roots extracting moisture from the soil or infiltrating pipes, causing underground leaks.
For example, poor drainage beneath a concrete slab was identified as a likely cause of settlement at a restaurant with a veranda in a brick-clad house near Belgorod. The homeowner was concerned that the entire building would require major repairs, including partial demolition of structures. Fortunately, after addressing the main drainage issues, the building was re-leveled within hours using Uretek technology, compared to the timelines required for replacement or other solutions.
Seismic activity, such as earthquakes, can temporarily destabilize soils—a process known as loosening—which can then lead to settlement.
Settlement can also occur when nearby excavation, tunneling, drilling, or piling work causes vibration and soil movement, affecting foundation stability. Whether it’s a neighbor building a pool, new pit developments in the area, or large infrastructure projects, it is crucial to understand the cause of settlement to address the problem effectively. Uretek’s restoration solutions can usually be applied with minimal impact, preserving the integrity of even the most delicate structures, such as churches or other heritage buildings, where foundations are often affected by deep excavations during restoration or repairs.
