Our CL-8812 Reinforced Hydrophilic Polyurethane Grout ranks among the Best Waterproof Coatings and serves as a core part of our systematic Waterproofing Solutions. As a key complement to our full series of Liquid Waterproof Coatings, this reliable Durable Coatings material is a single-component injection grout engineered for basements, pipe galleries, subways, tunnels and mines, ideal for concrete crack repair, curtain anti-seepage and structural reinforcement in hydraulic and underground transportation projects.
It instantly polymerizes on contact with water, foaming and expanding to form strong, elastic water-insoluble gel with large water absorption and wide penetration radius. Its reaction time ranges from dozens of seconds to minutes, featuring powerful substrate adhesion and stable pumpability even under low temperatures for simple single-liquid construction. For operation, drill 14mm holes and place injection nozzles 0.3–1m apart, inject grout fully and cut nozzles for sealing…
