Bathroom waterproofing for warehouses in Yanbu begins with the location itself. The centre of Yanbu sits about 6 m above sea level (SRTM open elevation data), and the town is about 1.2 km from the sea coast (OpenStreetMap). Because the ground is close to the coast, we check first how water moves across the floor and into the slab, and whether any drainage falls toward low points where moisture could collect. Our technicians look at the bathroom floor, the junctions with the walls, and the drain outlets before recommending any system. The typical bathroom waterproofing rate is SAR 15–40 per m², and the price for a particular job depends on the area and condition found on inspection.

Several things are left to the site visit, because they cannot be judged from a description. The technician needs to see the existing surface, whether there are cracks, how old the screed is, and whether the floor is level enough to hold a coating. Spray foam, at SAR 20–45 per m², suits some substrates, while epoxy coating, at SAR 35–90 per m², suits others, and a crack that needs injection is priced at SAR 40–120 per metre. The choice of material and the final quotation are settled only after the visit. Where a warehouse bathroom sits near a roof or a tank, the technician will also note any connected areas, since liquid roof waterproofing (SAR 8–25 per m²) and tank internal coating (SAR 25–60 per m²) are separate scopes that should not be mixed into one estimate.

To help the technician prepare, please tell us the approximate floor area of the bathroom, the building's age, and any past leaks or repairs you remember. Note whether the bathroom sits on a ground slab, and whether a basement or wall insulation with XPS boards (SAR 12–30 per m²) or bitumen membrane (SAR 15–35 per m²) is already in place. Share photographs of the cracks and the drain if you have them, and state which areas are in daily use so that work can be scheduled around them. With this information the technician can arrive ready to assess the site quickly.

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