Urethane grout injection is a specialized technique for repairing water leaks and stability issues in concrete. By injecting urethane-based grout into cracks and joints, this method seals leaks and reinforces the structure as the grout expands with moisture. Known for its flexibility, durability, and waterproofing properties, it's ideal for basements, foundations, tunnels, and water-retaining structures. This minimally invasive, cost-effective solution extends the lifespan of concrete by filling and sealing cracks, offering a long-term fix for complex waterproofing challenges.
