Hydrophobic Polyurethane Grout
BeiJing Langwei exports the polyurethane grout products.Hydrophobic polyurethane grout is a single component hydrophobic polyurethane infection resin, which after reaction with water, can expand rapidly to form permanent seals. Effectively seals cracks and prevent leaks in subway, tunnel, basement, underground garage, underground channel, diaphragm wall, culvert, dam, etc.
Short waiting time during the works.Rapid reaction with water and can complete foaming process.
The low viscosity makes better penetration. It can retain its properties when mixed with weak base or weak acid, even with seawater. Permanent repair and lint-term flexibility.
Hydrophobic polyurethane grout has high expansion rate, owned supreme bonding structural strength. Let you save more material.
Obviously reactive with water
High elasticity and higher strength
High waterproof efficiency
