Before we start: what we know about Hafr Albatin

The centre of Hafr Albatin sits about 312 m above sea level (SRTM open elevation data). Team note on Hafr Albatin: 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 first thing a technician checks in a restaurant bathroom in Hafr Albatin is the floor-to-drain fall and the state of the existing screed, because that is where water pools and where most failures start. The centre of Hafr Albatin sits about 312 m above sea level (SRTM open elevation data), so the ground there is not a flood basin, but heavy kitchen and washroom use still means water runs across floors all day. Before any product is chosen, the technician looks at where that water goes, whether the drain sits at the lowest point, and whether there are cracks near wall junctions or around floor traps. Bathroom waterproofing for this type of space typically falls in the range of SAR 15–40 per m², while epoxy coating runs SAR 35–90 per m², so the choice of system depends on what the surface has to withstand, not just on cost.

Several things are left to the site visit and cannot be judged from a description. The actual moisture content of the substrate, the presence of hidden leaks behind tiles, the condition of any existing membrane, and the traffic level of the room all change the recommendation. A technician will also check whether the walls need coating to the same height as the floor, how the sanitary fittings are sealed, and whether a crack needs injection before any surface layer goes on. Crack injection is priced at SAR 40–120 per metre, so measuring the length of visible cracks on site is part of the quote. Spray foam (SAR 20–45 per m²) and liquid systems may suit some edges and corners, but only once the substrate has been inspected.

To help the technician prepare, it is useful to have the approximate floor area of the bathroom, the number of drains, and a note of any past leaks or repairs. Photos of the walls and floor, taken in normal daylight, make it easier to plan the first visit. Tell us whether the bathroom is used only by staff or also by customers, since that affects how often the floor is wet. If there is a flat roof or a water tank above the washroom, mention it too, because liquid roof waterproofing (SAR 8–25 per m²) and tank internal coating (SAR 25–60 per m²) are sometimes needed in the same building. With this information, the site visit can focus on confirming the plan rather than starting from scratch.

For restaurants, visits are planned outside service hours and recorded for the premises file.

When do you need bathroom waterproofing?

The following signs are worth checking before they grow:

• Worn grout

• 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.
