Hydrophobic Polyurethane Grout

Hydrophobic polyurethane grout is a low-viscosity polyurethane grout designed for single-component injection. It penetrates fine cracks and reacts with water to form a flexible foam barrier that stops flowing leaks and seepages. Once cured, the hydrophobic seal repels water, will not shrink or expand, and serves as a long-term solution to water infiltration.
