PU Injection Grouting – SWC’s Secret Weapon Against Waterproofing Leakage
One of SWC’s most effective repair techniques is PU injection grouting — injecting polyurethane resin into cracks, joints, and voids in concrete.
Advantages of PU Injection Grouting:
- Seals Active Leaks – The resin reacts with water, expanding to completely block the leak.
- Durability – Remains flexible, accommodating small building movements without cracking.
- Minimal Disruption – No large-scale hacking required.
- Structural Reinforcement – Bonds with the concrete, improving its strength.
- Fast Turnaround – Many repairs are completed in just a few hours.
This method is particularly effective for ceiling water leak repair, bathroom ceiling leaks, and concrete repair in both residential and commercial settings.
