Bathroom waterproofing in warehouses is rarely about the bathroom alone. The most common problem for this property type is water working its way through floor and wall joints where the washroom block meets the warehouse slab, leaving staining, soft plaster and damp smells that spread into the storage area. Because warehouse floors are heavily loaded and often poured in large sections, hairline cracks at joints are typical, and they let water travel sideways under tiles that look perfectly sound from above.

Muhayil Aseer sits at about 455 m above sea level, so the approach needs to reflect a setting where weather can swing from hot, dry afternoons to cooler evenings and occasional heavy rain. Materials that tolerate movement and temperature change are preferred, and surfaces should be checked for moisture before any coating is applied, since trapped water beneath a membrane will push it loose over time. Where a joint is actively cracking, crack injection is usually priced per metre and is often the sensible first step before any wider coating is considered. For wet rooms and tiled washroom floors, a bathroom waterproofing budget of SAR 15–40 per m² is a common starting reference, while larger work such as tank internal coating at SAR 25–60 per m² or liquid roof waterproofing at SAR 8–25 per m² may be needed if water is also entering from above or from adjacent storage tanks.

Before the visit, ask the crew to explain how they will locate the source of the leak rather than only sealing the visible surface. Request a written scope that lists each area, the material chosen, and the rate per m² or per metre, so you can compare it against the ranges above. Ask whether the price covers surface preparation, moisture testing and disposal of damaged material, and how long the work will take so warehouse operations can be planned around it. Finally, confirm who will be on site, what warranty terms apply in writing, and how they will protect stored goods while work is underway.

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

Signs that call for bathroom waterproofing

These are the signs most often linked to bathroom waterproofing:

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

Causes we see in the field

• The area around the floor drain — we check this before anything else.

• A damaged floor layer.

Tools and methods, and when we use them

From the first visit to the report

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.
