Slab lifting with polyurethane consists of using a specialized two-part foam system that is injected directly under the concrete. 3/8” holes are drilled in a special pattern to optimize lifting with minimal visual impact.
As the materials mix and expand, the foam creates pressure under the slab to raise and level the existing concrete. This polyurethane mixture works flawlessly in wet and dry conditions because of its hydrophobic properties. Considering water infiltration is the leading cause of sinking slabs, a foam mixture that repels water is extremely beneficial to the life of the lift.
With densities of 2, 2.5 and 4 pounds, Rhino Linings has the slab lifting foam for your needs.
