Bathroom Waterproofing
Before Tiling
Bathroom waterproofing stops water leaking into the ceilings below and the walls around. Once tiled, you cannot see it, and a leak means breaking out. We take handover once, before it is covered.

What Is Bathroom Waterproofing?
Bathroom waterproofing is a layer applied to the bathroom floor and turned up the walls, before the screed and tiling. The bathroom waterproofing inspection is an engineering visit before covering, in which our engineers check that the waterproofing covers the floor and walls and is properly detailed around floor drains and pipes.
The inspection matters because most leaks in homes come from bathrooms, showing up as stains on the ceiling below or in adjacent walls. Repairing them after tiling means breaking up the floor and redoing the waterproofing and tiles.
Handover of Bathroom Waterproofing
We inspect the waterproofing once, after it is applied and before it is covered.

The last chance to see the waterproofing before the tiles cover it. We check coverage and thickness, and the detailing at floor drains, pipes and corners.
Key Items We Inspect
Surface Preparation
Floor clean and free of protrusions.
Thickness
Measuring waterproofing thickness with a thickness gauge.
Upstand on Walls
Height of the waterproofing up the walls and around the shower.
Floor Drains
Waterproofing detailing around floor drains.
Pipes
Detailing around penetrating pipes.
Flood Test
Flooding the floor with water and monitoring for leaks.
Most Common Problems at This Stage
Low Waterproofing Upstand
High- Cause:
- Waterproofing taken only a short way up the wall.
- Impact:
- Damp in adjacent walls.
Tears from Pipes
Medium- Cause:
- Pipes installed after waterproofing.
- Impact:
- A leak point that is hard to detect.

Tips Before the Inspection
To help you get more out of the visit.
Do
- Request the handover before the screed and tiling.

- Installing new pipes after waterproofing.
- Walking on the waterproofing before it is protected.
Frequently Asked Questions
Common questions about Bathroom Waterproofing.
Why do bathrooms leak more than anywhere else?
Because they have the most water, pipes and floor drains, and any weakness in the waterproofing at these points causes leaks into the ceiling below.
When should I request the handover?
After the waterproofing is complete, and before the screed and tiling.
How much does a bathroom waterproofing inspection cost?
From AED 700.
