PU Injection Grouting for Crack Repair & Waterproofing

PU Injection Grouting is a high-performance polyurethane-based chemical grouting solution specially designed for sealing cracks, stopping water leakage, and strengthening concrete structures. It is widely used in residential, commercial, and industrial construction projects for effective waterproofing and structural repair applications.

This advanced injection grout reacts quickly with water and expands inside cracks, joints, and voids to create a durable waterproof seal. The expanding polyurethane foam penetrates deep into concrete surfaces and blocks active water seepage permanently. It is ideal for repairing cracks in basements, retaining walls, tunnels, terraces, water tanks, lift pits, parking areas, dams, and underground structures.

Our PU Injection Grouting material offers excellent adhesion to concrete, brick, stone, and masonry surfaces. The low-viscosity formula ensures deep penetration into hairline cracks and difficult-to-reach areas, making it highly effective for structural rehabilitation and leak control treatments.

The product is compatible with manual and electric injection grouting machines and can be used for both residential and large-scale industrial waterproofing projects. Once cured, the grout forms a flexible yet strong waterproof barrier that resists moisture, chemicals, and environmental stress.
