Polyurethane Grouts

PolyFM-1C™ Injection Grout is a high-performance blend of hydrophilic and hydrophobic polyurethane resins, engineered for reliable crack repair and void grouting. When exposed to water, it expands up to 10 times its original volume to create a permanent, flexible, and watertight seal. Easy to use and clean, PolyFM-1C eliminates the need for costly equipment or messy setups. It comes packaged in convenient 10 fl. oz. caulk-style cartridges that fit any standard caulk gun, making application fast and simple.

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™-SLV is a super low viscosity, single component resin that is ideal for sealing fine cracks.
