Hydrophilic Polyurethane Grout

Hydrophilic polyurethane grout is a single component hydrophilic polyurethane injection 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.

Easy Application

Short curing times during the works.

Rapid reaction with water and can complete foaming process.

Water Stop

Hydrophilic polyurethane grout can absorb more than many times water, can make no water flowout from the leakage. The low viscosity makes better penetration.

Permanent Flexibility

High resistance to aggressive chemicals.

Hydrophilic polyurethane grout can retain its properties when mixed with weak base or weak acid even with seawater.
