Sunken concrete slabs can be lifted back into place with our two-component polymer foam 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. Polyjacking (a.k.a. slab lifting and concrete lifting) can be accomplished at a fraction of the cost and time required for replacement using our AP Lift series of resins. The Deep Lift® process may be necessary if deeper soil issues are undermining the slab or structure.
