AV-202 Multigrout is a single component, moisture activated MDI/TDI blended polyurethane injection resin. Designed for sealing active water leaks in large cracks or joints in concrete structures, it can absorb up to 12 times its weight in water creating a tough, impermeable foam or gel with superb adhesive qualities. AV-202 Multigrout is certified by UL for NSF/ANSI 61 - Drinking Water System Components.
AV-202 hydrophilic multigrout is a polymer solution which cures when reacted with water. It reacts freely with water in any proportion to form a strong film, gel, or foam of polyurethane. AV-202 Multigrout’s intended use would be to prevent water infiltration into sub-grade structures and pipes.
