Waterproofing beneath bathroom and shower finishes, with attention to drains, corners, pipe penetrations and the tile build-up.
Discuss your requirementsTiles and grout are finishes; they do not replace the waterproofing layer. Water can pass through joints and reach the screed or slab. A wet-area system needs continuous coverage and carefully detailed transitions at shower walls, door thresholds, floor drains and plumbing penetrations.
Coordinate substrate preparation, falls, drain position, corner reinforcement and wall upstands before the membrane is applied. Agree the inspection and testing stage before tiles cover the work.
First distinguish supply-pipe, waste-pipe and membrane leaks. Check hollow or loose tiles, moisture and the existing build-up before deciding whether removal or a compatible overlay is appropriate.
Confirm the wet-zone boundaries, equipment penetrations and cleaning conditions. Match the coating, adhesive and protection to how the area will be used.
Cementitious and tile-compatible liquid membranes can suit different wet-area build-ups. Select a complete compatible system, including reinforcement and the tile adhesive. The current technical data sheet sets application thickness, cure time and when water testing or tiling may begin.

Provide the number of bathrooms, floor area, shower layout, photographs, location and whether tiles are already installed. Identify occupied rooms, access limits and any suspected plumbing leak. Agree removal, screed or fall repairs, treatment boundaries, testing and tiling responsibilities in the written scope.

Regrouting may address a finish defect, but it does not repair a failed membrane or plumbing leak. Diagnose the source before choosing the repair.
Only where the tiles and substrate are sound and the selected system is compatible. Drain connections, thresholds, moisture and the adhesive build-up must be checked.
After the membrane has cured for the period required by the manufacturer and before covering it with tiles or screed. Agree the test method and duration for the particular system.
