Concrete is not waterproof. It is porous, and water passes through it under pressure. A pool shell without a membrane will lose water through the structure, and it will keep losing it.
Systems that work
- Polyurea or polyurethane liquid membranes, more flexible, used where movement is expected
- Sheet membranes, rare on pools because of the number of penetrations
The sequence
The membrane goes on after the shell is cured and rendered true, and before any tiling. Skimmers, returns, main drains, lights and the vacuum point are all places where water finds a route out, and each needs a proper collar detail.
The flood test
Account for evaporation with a floating bucket of water at the same level, so you compare like with like.
What matters in Dubai
Dubai pool work needs coordination with the property layout, drainage and the surrounding landscape. A clear scope should separate structural work from finishes and equipment. That makes it easier to see what is included before work starts.
What to check before work starts
The existing pool or room should be inspected as a complete system. Visible damage may sit beside a separate problem in the pipework, controls, waterproofing or ventilation. A written scope should identify the affected parts and state which surrounding surfaces need protection or opening.
The site around the pool affects the technical choice. Access, drainage, planting and the position of the plant room should be reviewed together. A design that ignores the property usually creates awkward maintenance access later.
