AV-315 Microfoam is a single component, moisture activated, polyurethane injection resin designed for sealing active water leaks in very fine cracks or joints in below-grade structures. AV-315 cures to form a dense, resilient, and impermeable closed-cell flexible foam.
• Stopping active leaks originating from fine cracks or joints in concrete
• Stop leaks in mines, tunnels, subways, and other dense formations
• For use in below-grade structures: basements, tunnels, utility vaults, etc.
AV-315 Microfoam is tested and certified for NSF/ANSI/CAN 61 - Drinking Water System Components.
