Lift-Up Concrete Lifting levels and lifts sunken concrete without the expensive cost and time lost in traditional replacement. Concrete lifting is done by drilling holes through the surface of the concrete slab and then pumping a concrete mix/slurry underneath using a high pressure hydraulic pump. As the hollows areas are filled, the slab will lift and level. Most concrete flat work can be lifted. We lift driveways, sidewalks, porches, basement floors, office floors, warehouse floors, cement park strips and curbs. We also do void filling which using a long nozzle to pump cement grout into voids which prevents future settling. Often times the work can be done in a day with minimal disruption. We offer a two year warranty on all work and have references available.
