Stop Leaks with Expanding Polyurethane Foam
Spetec PUR HighFoamer is a one-component, closed-cell, hydrophobic, water-reactive, solvent, and phthalate-free, low viscosity resin. It’s most commonly used for high-flow water leak shut-off and stabilization. It has a high rate of expansion combined with a lot of flexibility. For similar products, see the page on Leak Seal.
