Will a restaurant bathroom in Samtah need waterproofing, given how far it sits from the coast? Samtah's town centre stands about 61 m above sea level, and the town is roughly 22.6 km from the sea coast. Those facts mean the area is not low-lying ground that collects water at the surface, but a busy kitchen-and-washroom setting still puts constant moisture on floors and walls. Bathroom waterproofing in this range is typically priced at SAR 15–40 per m², so a restaurant owner can budget for the washroom area on a per-square-metre basis before any work starts. Epoxy coating, at SAR 35–90 per m², is one option for surfaces that take heavy cleaning, and spray foam, at SAR 20–45 per m², is another to compare against it.

The inspection begins with a walk through the washroom and the rooms that sit beside it, looking for staining, soft plaster, and signs of water tracking along joints. The technician measures the floor and wall area that will be treated so the quote reflects real square metres rather than estimates. Where cracks are visible, the crack is traced and its length recorded, since crack injection is charged per metre at SAR 40–120 per m. The inspection also checks whether the surface is sound enough for coating, because a membrane applied over loose material will fail early. Any area that needs more than a surface treatment is marked so the owner can see the scope before agreeing to it.

Before the visit, gather the restaurant's floor plan or a simple sketch showing the washroom, the adjoining kitchen wall, and any floor drains. Note where leaks or damp patches have appeared and roughly when they started, because that history helps the technician pick the right method. Clear the washroom of fittings where possible and make sure someone who knows the building can grant access at the agreed time. If the premises have a water storage tank or a basement store, mention those too, since tank internal coating is priced at SAR 25–60 per m² and basement waterproofing at SAR 50–150 per m², and the inspection can cover them in the same visit.

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