Epoxy / PU Injection Grouting is an advanced repair and waterproofing solution used to seal cracks, eliminate active water leakage, and strengthen damaged concrete structures. Epoxy injection is ideal for structural crack repairs, as it restores the original strength and monolithic integrity of concrete by bonding cracked sections together. Polyurethane (PU) injection grouting is designed to stop active water seepage and fill voids by reacting with moisture to form a flexible or rigid waterproof seal, depending on the application. These systems are widely used in basements, foundations, retaining walls, tunnels, bridges, parking structures, water tanks, dams, lift pits, swimming pools, and underground structures. Suitable for both dry and wet conditions, Epoxy / PU Injection Grouting provides excellent adhesion, durability, chemical resistance, and long-term protection against water ingress, making it an effective solution for residential, commercial, industrial, and infrastructure repair projects.
