Fixing Sinking Slabs
We understand the ins and outs of concrete as a building material, and we know the proper ways to go about fixing it so that it doesn't experience problems again in the future. It's important to understand that your damaged and sinking concrete slabs can lead to additional problems if the problem isn't taken care of immediately. These problems include everything from concrete leaks and cracks to sinking garage floors, stairs, parking lots, and so on.
To take care of this common problem, we make use of a concrete raising and leveling technique known as polyjacking. It is comparable to mudjacking or slabjacking, except instead of a messy concrete mix, we make use of a foaming polyurethane resin instead. The foam is inserted through tiny holes that are drilled into the concrete slab. The foam expands and it fills up the entire void beneath the surface. This provides enough force to lift the slab back into place where it belongs. The entire process can be finished in a few hours and the foaming material cures within 15 minutes. Afterward, it can be walked on and driven over like normal once again.
