Waterproofing Resins & Coatings
FlexFoam PU-110 Rapid Injection Resin
In StockFast-reacting single-component polyurethane that foams into a flexible, water-tight seal — ideal for emergency leak stopping.
FlexFoam PU-110 is the resin reach for when water is pouring in and you need it stopped now. Its rapid, water-triggered reaction creates an expanding flexible foam that chases the leak path and locks it shut.
The set speed is tunable with our PU accelerator, letting crews dial in the reaction to match the rate of water ingress.
