Spray Foam Concrete Raising

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.

A hole is drilled through the slab into the subgrade. A tapered delivery port is installed into the concrete slab hole. The injection gun is connected to the port.



The injection gun delivers the polyurethane material through the port and slab. Expansion of the material occurs within seconds, compressing loose soils and raising concrete.



Holes are patched and clean up is performed in minutes.


Inexpensive, Faster, Greener, Minimally minimal mess

When compared to concrete replacement, the process of raising concrete with our polyurethane foam is inexpensive. It is also exponentially faster than replacing concrete. Repaired areas are ready within minutes to be utilized, as they were intended.
