PU injection grouting is a cost-effective method to address persistent leaks without major repairs. The polyurethane resin bonds tightly to concrete, sealing cracks even in hard-to-reach areas. This technique is widely used for basement leaks, wall seepage, and slab repairs. PU injection grouting ensures lasting waterproofing and improved structural integrity. https://shakuraconstruction.sg/services/pu-injection-grouting/
