Even when planned and designed properly, buildings can shift and sink over time as the soil beneath then erodes. This can be quite a costly problem for the owners. If left unaddressed, it can spell the end for a structure within a few short years. Fortunately, there is a way to stop the erosion and stabilize the soil beneath the building to prevent further shifting.
Foamjacking - A New and Revolutionary Solution
Years ago, the only way to rescue buildings undergoing this problem was to pour asphalt over the cracks and holes that appeared as the concrete slabs begin to shift. This was not a permanent solution. Now, there is a much better, and longer-lasting option using the most advanced materials for your construction projects -- foamjacking.
Foamjacking involves inserting polyurethane foam beneath the surface of the concrete floor slabs. TerraThane foam is pumped under the concrete, through small holes, and forms a supportive layer between the building and the soil. The concrete slabs are lifted back into their original positions by the foam.
Results and Advantages of Foamjacking
- Since the foam used for foamjacking is so light, it does not present an additional burden to the already eroding soil.
- TerraThane foam is very dense, so it is capable of supporting the weight of the heavy concrete structure on top of it.
- The foam conforms easily to all shapes, which allows it to fill in irregular cracks and crevices.
- The results of foamjacking are long-lasting, unlike older temporary methods of dealing with erosion beneath buildings.
