Bathroom & wet area waterproofing in Dubai
A leaking shower is rarely about grout. We find where water is really escaping — the tray, the drain, the wall junction — and rebuild the waterproofing under the finish.

Overview
Bathroom & Wet Area Waterproofing: scope, systems and delivery
Wet-area leaks are among the most common calls we get from Dubai apartments and villas, and among the most misdiagnosed. Re-grouting and silicone hide the symptom for a few weeks while water keeps soaking the screed, the wall behind and the ceiling below — where mold quietly takes hold.
We use moisture mapping and thermal imaging to locate the escape path, remove only what's necessary, and install a continuous liquid membrane with reinforced corners, sealed drains and upstands at every wall — before tiles go back on. Kitchens, laundries and plant rooms get the same treatment.
The right specification starts with the condition of your property and the work it needs.

Before you appoint a contractor
Bathroom waterproofing and shower leak repair: what to check in your quote
The final scope follows inspection. Ask for preparation, materials, access, testing and reinstatement to be itemised so you can compare proposals fairly.
Define the work included
- Wet-area floor, wall junctions, shower details and pipe penetrations
- Preparation, compatible membrane and agreed testing before finishes
Items that may cost extra
- Tile removal and replacement
- Plumbing repairs, sanitaryware removal and ceiling decoration below
What to send for an accurate quotation
Bathroom layout, affected floor below, photos, pipework history and whether tiles can be removed.
Comparing proposals
Confirm how membrane continuity around outlets and corners will be tested before tiling and whether plumbing defects are a separate repair.
Changes to price and programme
Concealed damage, additional areas, changed materials or access restrictions can change the work. Ask for the extra cost, revised completion date and any effect on testing or warranty to be recorded and agreed before additional work proceeds.
Testing, handover and warranty
Confirm the inspection or testing method, completion records, aftercare and written warranty for the selected system. Coverage, duration, exclusions and maintenance requirements should be stated for your specific project.

FAQ
Questions about bathroom & wet area waterproofing
More answers on our FAQ page, or speak to an engineer directly.
Can a shower leak be fixed without retiling?
Occasionally — if the leak is a failed drain seal or a single penetration. If water is passing through the tray or walls, the membrane beneath the tiles has failed and the area needs to be rebuilt properly.
How long will my bathroom be out of use?
Typically three to five days for a standard bathroom, including the flood test before tiles are reinstated.
Is the mold behind the tiles dangerous?
Hidden mold affects indoor air quality and can aggravate allergies and asthma. We treat it as part of the repair and can test air quality afterwards.
