I recently assisted on a job in which a large void underneath a homeowner’s garage had caused the slab to sink. Our marketing team got some GREAT time lapse footage of the slab lift.
Quick recap for those who are new to polyurethane slab lifting: Concrete slabs settle due to voids or unstable soil below. By pumping a polyurethane foam through the concrete, you essentially push the concrete slab back up from below. Using polyurethane foam is very cost effective, environmentally friendly, and causes very little downtime.
