Hydrophobic Polyurethane Grout

Hydrophobic polyurethane grout is a catalyzed hydrophobic polyurethane liquid. It expands when it meets any source of water or moisture before curing. The product adheres tenaciously to practically any substrate - wet or dry.

Grout is used to stop leakage through cracked or honeycombed concrete, voids, expansion joints and pipe intrusions. Applied by injection, the grout is commonly specified to repair concrete walls, ceilings and floors. It is also recommended for use in tunnels, manholes, sewer lines, tanks, dikes, and dams.It has excellent chemical resistance and may be used in a wide range of chemical environments.
