Sunken concrete slabs can be lifted back into place with two-component polyurethane foams designed to work in wet or dry conditions. The expansion force of the concrete leveling foam coupled with the pressure of a specialized pump generate enough controlled force to lift virtually any structure back into position with 1/8” precision. 

Alchemy-Spetec's AP Lift 430, AP Lift 440 and AP Lift 475 are the most dependable foams for jacking and leveling concrete slabs.
