Not too long ago, I had the opportunity to assist on a concrete leveling job involving a sunken garage slab. This particular slab had a massive void underneath that needed to be filled before the slab would lift. In just a few hours, we had the void filled and the slab level again.
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.
