We use Polyurethane Injection Foam to Raise Settled Concrete
in the Greater Kansas City Area. Leaving a flawless transition between slabs.
How It Works
Our polyurethane foam method uses the concrete slab itself as a means of delivering poly foams that raise concrete, fill voids, and stabilize soils. A ⅝” hole is drilled through the slab into the subgrade. A tapered delivery port is installed into the ⅝” 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.
A precise and easy process –
Raising concrete with polyurethane foam is done with incremental injections. Lifting foam will fully expand within 10-15 seconds allowing us to monitor the raising and preventing over raising the slab. By using an air-purged gun to deliver foam under the slab, we have complete cont
