Polyurethane concrete raising is used to raise and support sunken or unstable concrete slabs.

Our polyurethane foam method uses the concrete slab itself as a means of delivering poly foams that raise concrete, fill voids, and stabilize soils.

Raising concrete with polyurethane foam is done with incremental injections. Lifting foam will fully expand within 10-15 seconds allowing you to monitor the raising and preventing over raising the slab.
