Undersealing is used to fill a void under concrete slabs. Industrial applications include concrete streets, factory and warehouse floors, roadways, and bridge approaches.
Helitech Civil Construction Division utilizes a state-of-the-art technology as an undersealing solution. Instead of breaking up, removing, and repouring the entire concrete slab, Helitech CCD inserts a special Polyurethane combination below the surface to fill voids below the existing concrete.
By utilizing the Polyurethane method, Helitech CCD has the ability to fill voids below concrete slabs without adding the extra weight of the concrete to an already settling soil. Compared to Traditional Mudjacking which adds an additional 100 pounds per cubic foot, the Polyurethane Material is only 2-5 pounds per cubic foot depending on the density being used. Polyurethane Concrete Leveling from Helitech CCD is a green solution as the poly foam used is made from recycled material.
