It is conventional one component water-soluble polyurethane hydrophobic foam, react with water rapidly to be solidified and expansion to sealing the crack. After reaction with water to form milk-white elastic gel, with advantage performances of fast speed, high strength, and little shrinkage, strong penetration-proof etc., widely used in waterproof works such as the tunnel, the subway, dam, underground garage, sewers, etc.
