Bathroom waterproofing for warehouses in Sabya starts with the location itself. The centre of Sabya sits about 40 m above sea level (SRTM open elevation data), and the town is about 16.7 km from the sea coast (OpenStreetMap). Because of this, our technicians begin by looking at how water will move across and away from the floor rather than assuming it will pool or drain in the same way it would on the coast. The first checks are the existing floor falls, the drainage outlets, and any sign of past moisture on the walls and skirting, since these show where water has already been getting through.

Several items are left to the site visit, because they depend on what is physically present in the building. The technician will check the condition of the substrate, look for cracks and their length, and confirm whether the surface is dry enough to take a coating. They will also measure the bathroom area, since pricing for bathroom waterproofing runs at SAR 15–40 per m², and the final figure depends on the exact square metres and the condition of the surface. If the existing finish has to be removed, or if a different system such as epoxy coating at SAR 35–90 per m² or spray foam at SAR 20–45 per m² suits the surface better, that choice is made on the spot after inspection rather than before it.

To help the technician arrive prepared, please have the following information ready: the approximate floor area of each bathroom, any plans or sketches showing the drain positions, a note of where leaks or damp patches have appeared, and the access arrangements for the warehouse so work can be scheduled without disrupting stock. Photographs of the affected walls and floors are also useful, particularly any cracks that have been noticed. Clear details at this stage mean the visit can focus on confirming the work rather than gathering basic facts, and the proposal that follows will reflect the real conditions of your building.

For warehouses, work is phased around operations and stored goods.

When do you need bathroom waterproofing?

The following signs are worth checking before they grow:

• A stain under the bathroom on the floor below
• Damp around the shower
• Worn grout

The most common causes

• Corners without waterproofing tape — we check this before anything else.
• A damaged floor layer.
• The area around the floor drain.

Tools and methods, and when we use them

The steps in order

1. Finding the source: A supply-pipe leak is ruled out first.
2. Preparation: The floor is opened and cleaned where needed.
3. Corners and details: Tape and detailing at corners, drains and pipe entries.
4. Flood test: The floor is tested before tiling.
