Frequently Asked Questions

Q: What is PU Injection and how does it work?
A: PU (Polyurethane) Injection is a technique where specialized resin is injected into cracks under pressure. The resin expands to fill all voids, then cures to form a permanent, flexible waterproof barrier.
Q: How long does PU Injection last?
A: Properly applied PU Injection typically lasts 10+ years, often for the lifetime of the structure when done correctly.
Q: Can you inject active leaks?
A: Yes! We use hydrophilic resins specifically designed to cure in wet conditions and stop active water flow.
Q: Is PU Injection better than epoxy?
A: For waterproofing, yes. PU is more flexible than epoxy and better accommodates structural movement while maintaining its seal.
Q: How soon can the area get wet after treatment?
A: Most PU resins cure fully within 24-48 hours, after which the area is immediately waterproof.
Q: Do you provide warranty for PU Injection?
A: Yes, we offer a 5-year warranty on all our PU Injection workmanship and materials.
