What is PU Grouting?
PU Grouting, or polyurethane injection grouting, is a proven waterproofing method that seals cracks and prevents water infiltration. This technique involves injecting high-performance polyurethane into cracks and voids under controlled pressure. The resin expands and hardens, forming a watertight seal that strengthens the structure.
This method is commonly used in Singapore for concrete repair, sealing cracks and voids in basements, swimming pools, walls, ceilings, and other leak-prone structures.
