Poor Compaction, water erosion, broken pipes, and organic material in the soil can all lead to settling of concrete slabs or a roadway. Traditional slab lifting can bring concrete slabs back into place but, it doesn’t necessarily address deeper underling soil issues.
Helms Polyfoam employs a unique combination of high quality expanding chemical grout that is pumped deep into the weak soils. This process penetrates multiple layers in the soil to create levels of high density polymer and tightly squeezed soil. This displaces the soil and increases its old bearing capacity.
