Injection Grouting
Protect Your Building with PU Injection Grouting
PU Injection Grouting is an effective waterproofing technique used to seal cracks, joints, and leakages in concrete structures. Polyurethane resin is injected under pressure, where it expands and reacts with water to form a flexible, durable, and watertight barrier that stops active leaks instantly.

PU Injection Grouting Process
Assessment & preparation: Identify leaks, cracks, and weak points; clean and prepare the surface for injection.
Drilling injection ports: Strategically drill holes along cracks and joints to ensure proper resin penetration.
Resin injection: Polyurethane (PU) resin is injected under pressure, expanding to fill voids and seal leaks.
Curing & inspection: Resin reacts with water, forming a flexible, waterproof seal; final checks ensure complete leak stoppage and structural integrity.
Benefits
