CL-8813 Standard Hydrophobic Polyurethane Grout

Our CL-8812 Standard Hydrophobic Polyurethane Grout ranks among the Best Waterproof Coatings and acts as a core component of our integrated Waterproofing Solutions. Matched perfectly with our full lineup of Liquid Waterproof Coatings, this series of Durable Coatings is a single-component injection material designed for basements, pipe galleries, subways, tunnels and mines to seal concrete cracks and expansion joints. It expands up to 25 times after mixing with water without shrinkage, fully filling micro-pores and structural gaps. Free of chloride ions, it avoids corrosion to steel bars inside RC concrete structures, and excess overflow residue can be easily cleaned after construction. Its curing time and solid strength are adjustable based on water ratio and ambient temperature, and the cured foam resists weak acid and alkali erosion. For construction, drill holes at seepage points and inject the grout continuously; repeat injection 2–3 times for heavy water leakage below the wate…
