AV-330 Safeguard

AV-330 Safeguard

AV-330 Safeguard is a 100% MDI-based, single component, mid-range viscosity, moisture activated polyurethane injection resin designed for sealing active leaks in below-grade structures. AV-330 permeates well in various cracks and joints, but offers added safety in confined spaces or where there is poor ventilation. AV-330 cures to a resilient and flexible, yet tough, closed-cell foam. 

• Areas with poor ventilation or confined spaces (utility vaults, subgrade pump houses, lift stations, mines, tunnels, and basements)
• Medium cracks or joints in concrete structures
• Great for manholes and pipe penetrations 

AV-330 Safeguard is certified for NSF/ANSI/CAN 61 - Drinking Water System Components.
