PU injection grouting is a highly effective method to stop water leaks by injecting expanding polyurethane resin into cracks and voids. Once injected, the material reacts with moisture, forming a strong waterproof seal. PU injection grouting is ideal for basements, walls, roofs, and concrete structures, delivering long-lasting leak prevention and structural reinforcement. https://shakuraconstruction.sg/services/pu-injection-grouting/
