Concrete leveling in driveway. All slabs of the driveway were uneven and settling at different points. We were able to come out and lift all these sinking areas and level them out.
This home had numerous sunken slabs that we were able to repair with our PolyLevel product.
Concrete lifting has come a long way. We use high-density polyurethane foam that goes under the concrete through penny sized holes that we drill into the concrete. We raise the slab or fill the void that is under it and then fill in the holes so you would never know they were there. The foam sets in about 15 mins so need to wait too long before using the space again.
