Before we start: what we know about Tabuk

The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data). Team note on Tabuk: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins..

The centre of Tabuk sits about 762 m above sea level, according to SRTM open elevation data, and that height shapes where we start. Before quoting any figure, the technician checks the existing floor and wall surfaces for moisture, cracks and old membrane, because a bathroom in Tabuk is often tested first for how water currently moves through it. Bathroom waterproofing is typically priced at SAR 15–40 per m², and the final figure depends on the surface condition found at the start, not on the size of the room alone. Cracks are noted separately, since crack injection is priced at SAR 40–115 per metre, and each joint is measured so it can be listed on its own line.

What is left to the site visit is the decision about the right system for each area. The technician compares the options that suit a wet room: epoxy coating at SAR 35–85 per m², spray foam at SAR 25–35 per m², and bitumen membrane at SAR 15–35 per m². Where a bathroom sits above another space or shares a wall with a tank, the visit also covers whether tank internal coating at SAR 25–55 per m² or XPS boards at SAR 10–30 per m² would fit the layout. Basement waterproofing, at SAR 50–145 per m², and liquid roof waterproofing, at SAR 10–25 per m², are only considered if the inspection shows the water is coming from those parts of the building. Nothing is confirmed until the surfaces have been examined in person.

To help the technician, the resident should note where water has been seen, how long the floor stays damp after showering, and any cracks or stains on walls and ceilings. Please mention the age of the existing tiling, whether a previous sealant was applied, and whether the bathroom is on the ground floor, an upper floor or above a water tank. Clear access to the drain, the shower tray and the wall behind the toilet saves time on the day. Having this information ready lets the visit focus on the points that actually decide the method and the measurements.
