PolyFM™ Injection Grouts are hydrophobic polyurethane injection grouts designed to permanently seal water leaks and fill voids in concrete and masonry structures. Upon contact with water, these resins rapidly expand to form a tough, flexible, and resilient closed-cell foam, creating a permanent watertight barrier.
PolyFM™-LV is a low viscosity, two-component resin available in convenient dual cartridges for repairing wider cracks and voids.

Description
PolyFM-LV™ Injection Grout is an innovative blend of hydrophobic polyurethane resins designed to provide the ultimate solution for crack repair and void grouting applications. In contact with water, PolyFM-LV will expand up to 10 times its original volume creating a permanent, flexible and water-tight seal. POLYFOAM-LV eliminates the need for costly equipment and messy cleanups. PolyFM-LV is packaged in dual 22 oz. cartridges that easily dispensed in most standard dual-cartridge dispensers.
