Cracks in walls and uneven floors are often symptoms of a problem. Many structural problems are associated with unstable soil conditions or subsidence. To eliminate these problems, it is important to understand not only the visible effects on the building or structure, but also what happens in the soil itself. Different types of soils give rise to different problems and require different solutions. Having an expert on hand who knows how to behave and what to do can help ensure that when you solve one problem, you are not causing another.
Misunderstanding can lead to disastrous results. As an example, one apartment building suffered damage after a trench dug under the floor to fix a leaking pipe (pipe replacement technology involved opening the floors) was again filled with sand. The house was built on a heaving (swelling) clay base. A sand-filled trench created a canal that diverted groundwater under the house, saturating clay and, like the effect of heaving, unevenly lifting various parts of the building. As a result, the repair of the pipe caused much more significant damage to the building than just a burst pipe, because the type of base soil was not taken into account when choosing a solution.
The volume of heaving clay varies with humidity. It (soil) swells when wet (or frozen) and contracts when dry. In dry areas, visible cracks appear in the ground when it shrinks, and most people are familiar with the sticky, slippery wet clay soils that get stuck on your shoes. Design problems often arise when there are different levels of moisture in the soil below, causing subsidence in drier zones, or rise in wetter zones.
An additional difficulty with clay soil is that during glut, it loses its strength and its bearing capacity decreases. The supporting structures bend through the weakened zone and settle. This has a double effect when the soil dries later and the foundations sink even further.
GeoResin designs its solutions taking into account heterogeneous layers of soils and features of their behavior. And also when interacting with GeoResin resins in various conditions. Understanding this, engineers choose the right type of material and technology, which, when implemented, displace water from the problem soil, replacing it with itself and forming a hydraulic barrier for the future. As a result, the soil loses its predisposition to heaving and at the same time increases its bearing capacity.
