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.
