H2O Xpanda PU 2.7 is a single-component hydrophobic polyurethane injection resin engineered for rapid sealing of active water ingress in concrete and masonry structures. When in contact with water, the resin reacts aggressively to form a dense, closed-cell foam that expands to block flowing leaks.

With expansion of up to 27× its original volume, Xpanda PU 2.7 is suited to emergency leak-stoppage and high-pressure water ingress scenarios where immediate control is required. The cured foam remains dimensionally stable and tolerant of structural movement.

This product is widely used for basement leaks, tunnels, tanks, service penetrations, and defective concrete where water is actively migrating through cracks or joints. Exclusive to H2O Supplies.
