Avanti AV-202 Multigrout – 1 Gallon
Avanti AV-202 Multigrout is a single-component, moisture-activated polyurethane resin engineered for sealing active water leaks in large cracks and joints. It reacts with water to form a flexible, impermeable foam or gel, expanding up to 600% while adhering tightly to concrete surfaces. AV-202 is ANSI/NSF 61 certified for potable water use, solvent-free, and designed for use in high-volume flow conditions such as manholes, pipe penetrations, and below-grade structures. It can absorb up to 12 times its volume in water and performs in wet or underwater environments.
This product is also available in a bulk 5 Gallon unit.
Key Features:
- Hydrophilic polyurethane reacts with moisture to form resilient foam
- Expands 400–600% to seal large joints and cracks
