Pu injection grouting service About
PU (Polyurethane) injection grouting is a specialized waterproofing method used to immediately stop water leakage in concrete structures. It involves drilling holes near cracks and injecting liquid resin under high pressure. The resin reacts with water, expands up to 27 times its volume, and hardens into a dense, flexible seal.
