Bathroom waterproofing: Reinforcing tape embedded in grey waterproofing at a bathroom wall-floor corner

Bathroom waterproofing Keeping water inside the bathroom

A stain on the ceiling below the bathroom or damp on the wall next door? The bathroom needs a proper waterproof layer starting at the floor and corners.

How we work

From your call to the right waterproofing

  1. 1

    Tell us what you see

    Call or message us on WhatsApp and describe the bathroom: is it under construction or finished, and where does the damp appear.

  2. 2

    We assess the condition

    We check the floor, the walls, the corners, the pipe openings and the drain level, to know exactly what this bathroom needs.

  3. 3

    We prepare the surface and waterproof it

    Surface preparation is essential: it is cleaned, levelled and cracks are treated before the waterproof layer goes on the floor, walls and corners.

  4. 4

    We seal the edges and openings

    The junctions between the floor and the walls, the pipe openings and the drain edges are where waterproof layers fail first, and they are treated with care before the job is done.

Questions

Questions about Bathroom waterproofing

Before tiling, the waterproof layer is put straight onto the prepared floor and walls, then tiled over, which covers the whole surface. After tiling, the joints, cracks and corners are treated, and tiles may have to come up if the problem is deeper. Each stage has its own approach.

Water follows the slope of the floor and gaps inside the slab, and it pools at a point away from where it entered. So the repair point is not set by the stain alone; the whole bathroom floor above it is checked.

In some cases yes: if the problem is in the joints, the corners or around the drain it can often be treated without lifting the tiles. If the waterproof layer under the tiles is missing or has fully failed, the tiles may need to come up to reach the floor. This is decided after inspection.

Dark stains or damp on the ceiling of the room below, peeling paint on the wall next door, salt appearing on the walls, or a mouldy smell with no visible source. All of these point to water leaving the bathroom into the surrounding structure.

The principle is the same: protect the floor, walls, corners, pipe openings and drain. But a small toilet room can have a limited area and many corners that need careful sealing. Both need a waterproof layer under the tiles to do their job.

Tell us whether the bathroom is under construction or already tiled, and where the damp appears: on the ceiling below, on the wall next door or inside the bathroom itself. If you know when the problem started, that helps us decide what to check first.

Yes, and the work usually covers treating the joints, corners, pipe openings and drain without major changes to the bathroom. If the case needs tiles removed or the floor prepared again, that is agreed after inspection.
