InjectPro-SuperFAST is a very fast reacting, expansive hydrophobic polyurethane injection grout. It cures to a rigid, durable, closed cell polyurethane foam resistant to most organic solvents, mild acids, alkali, petroleum and micro-organisms. InjectPro-SuperFAST is designed to stop active water leaks and fill voids in concrete, gravel layers and rock fissures. The closed cell foam will maintain its physical form and is not subject to shrinkage due to wet/dry cycles.
