Introduction
A902 Single Component Hydrophobic PU Grout (PU Foam) is designed to stop water leaking through the crack. When liquid urethane reacts with water, it begins to foam and expand to fill the crack. Once the urethane has foamed and expanded inside the foundation crack, water cannot leak into the construction.
A902 PU Grout is a single component hydrophobic polyurethane injection resin, which after reaction with water, can expand rapidly to form permanent seals.
