PU Injection Grouting is a highly effective waterproofing and structural repair technique that involves injecting polyurethane (PU) resin into cracks, joints, or voids in concrete structures. When injected, the PU resin reacts with moisture and expands to form a flexible yet strong waterproof seal that prevents water leakage and strengthens the structure. It is ideal for sealing active water leaks, filling voids, and stabilizing weak structures. PU Injection Grouting is widely used in basements, tunnels, retaining walls, and water tanks, offering a long-lasting and cost-effective solution for structural waterproofing and leak sealing.
