MYK ArmGrout Inject PU1 Low-Viscosity PU Grout for Structural Crack Sealing

ArmGrout Inject PU1 resin is a solvent free polyurethane injection material which is used in conjunction with ArmGrout InjectPU1 catalyst. ArmGrout Inject PU1 foams with water contact by high increase in volume and becomes firm visco elastic foam,which seals temporarily against further water penetration. ArmGrout Inject PU1 is resistant against acids and lyes and attacksneither bitumen nor joint tapes. In case of very dry surfaces the material does not foam immediately but it hardens slowly dueto the steady addition of existing air resp. soil moisture.
