Bathroom waterproofing and tanking.
Bathroom waterproofing Dubai done as a system — falls corrected, membrane applied with proper upstands, then flood tested before a single tile is laid.
The layer that decides everything else
Water sitting on a bathroom floor finds any gap in the membrane, tracks through the slab and appears as a stain on the ceiling below — usually weeks later and several metres from the actual fault. By the time it shows, the finished room has to come apart.
That is why we treat waterproofing as its own scope with its own sign-off: substrate prepared and primed, falls corrected, membrane applied to floor and wet-zone walls with correct upstands and corner detailing, then a flood test held before tiling. It adds days, not weeks, and it is what separates a bathroom that lasts from one that gets rebuilt.
What waterproofing covers
New bathrooms, wet rooms and repairs to failed installations.Investigation
Establishing whether the leak is the membrane, a pipe, the drain connection or the shower screen seal.
Strip-out
Removing tiling and finishes back to a sound substrate — membranes cannot be verified through tiles.
Falls correction
Re-screeding so water runs to the drain instead of ponding in a corner.
Liquid membrane
Two-coat liquid applied to floor and wet-zone walls with reinforced corners, junctions and penetrations.
Upstands and detailing
Membrane carried up walls to the required height and dressed into drains, thresholds and pipe penetrations.
Flood testing
Water held on the floor and checked before tiling — the only real proof the system works.
Balcony and terrace tanking
External membranes over occupied space, detailed at doors and parapets.
Reinstatement
Tiling, sanitaryware and making good after the waterproofing is signed off.

Who this is for
Leaking bathrooms and any bathroom being retiled.
This is one element of a full bathroom renovation — strip-out, services, waterproofing, tiling and fit-out.

Waterproofing questions.
Surface sealers exist but they are a temporary measure at best. A genuine membrane sits under the tiling, so proper waterproofing means stripping out first.
Ceiling stains below, damp or blown plaster on adjacent walls, loose tiles, or a persistent musty smell. Any of these warrant investigation before more damage accumulates.
The drain is temporarily plugged and water held on the finished membrane for a set period while the areas below are monitored. It is the only reliable proof before tiling.
Application is quick; curing and testing are not. Allow several days within the overall bathroom programme — compressing it defeats the purpose.
In wet zones, yes — shower walls and a set height around baths. Water runs down walls and into the floor junction, which is exactly where failures start.
Stop the leak properly.
