RaiseRite Concrete Lifting offers two different methods to raise settled concrete. This video illustrates the polyurethane concrete lifting option. Polyurethane is injected under the sunken slab. This polyurethane fills the voids, and expands to raise the concrete. After seconds, the material expands into a foam that will never lose density. Raising settled concrete is the cost-effective solution, when compared to replacing good concrete.
