How does Polyurethane Concrete Raising work?
High density expanding polymers are injected into ports through small 5/8” pre-drilled holes through to the underside of the concrete.
As part “A” and part “B” of the materials make contact at the gun tip, the mixture heats up and begins to expand, custom filling voids under the slab and this reaction causes the slab to lift.
The foam will never change shape and is water & erosion resistant.
The technician observes the entire slab over the course of the procedure pumping at small intervals; until the slab has reached an even, aligned or correct pitch elevation with the adjacent concrete.

“We’ve seen a lot of sunken and sloping concrete over the years when assessing leaky basements. Improper grade can be direct causes and/or certainly contribute to water infiltration in the basement”.
