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.
You can see in the photos that the concrete in front of the door had sunk quite a bit. This type of situation causes a tripping hazard and no one wants that. We were able to raise the concrete and eliminate the trip hazard while also making the appearance better.
This home had numerous sunken slabs that we were able to repair with our PolyLevel product.
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.
In mid Wisconsin it's not unusually for homes to see a lot of flooding due to the high water tables there. For this customer that was also the case and our solution was to pour a new floor over the existing to raise up the floor not allow the water tables to flood his basement. It is now a dry usable basement!
