Frequently Asked Questions

How much does PU injection waterproofing cost in Dubai?

Cost depends on the size and severity of the leak, the number of injection points needed, and how accessible the site is. We offer a free on-site inspection and give you a transparent quote before any work starts.

Is PU injection a permanent waterproofing solution?

Yes. Once the polyurethane foam expands and cures inside the crack, it forms a durable, flexible seal that stays effective for years. It's also backed by our service warranty.

How long does PU injection waterproofing take?

Most residential leaks are sealed within a single day. Larger commercial or structural jobs may take a bit longer depending on how many injection points are required.

Can PU injection stop active water leaks?

Yes. PU injection is built specifically for active, ongoing leaks. The foam expands on contact with water, sealing the crack instantly even while water is still flowing.

Does PU injection work for basement and foundation cracks?

Yes. PU injection is one of the most effective methods for sealing basement walls, foundation cracks, and below-grade structures, without needing excavation or major demolition.
