Picture a restaurant owner in Alrass who has just opened a kitchen store in the basement, where dry goods, cold storage and dishwashing equipment all sit below ground level. After the first heavy rain, the floor shows damp patches, the walls smell of mould, and stock on the lower shelves has to be moved. The owner is worried about food safety, lost inventory and the cost of closing the kitchen for repairs during busy trading weeks.

The local facts matter here. The centre of Alrass sits about 695 m above sea level, so the site is not in a low-lying hollow, but a below-ground space still needs its walls and slab protected from moisture pressing in from the surrounding soil. For a restaurant basement, the main work is usually basement waterproofing, priced at SAR 50–150 per m², and crack injection, priced at SAR 40–120 per metre, if cracks are visible in the walls. Where a wet area such as a washroom or prep sink sits below ground, bathroom waterproofing at SAR 15–40 per m² applies. Owners should compare these rates against the floor area and the length of cracks, rather than accepting a single lump sum without detail.

A practical sequence starts with a survey. First, walk the basement after rain and mark every damp patch, crack and stain, and note where water enters. Second, decide which areas are structural and which are finishing, because a crack needs injection before any coating goes on top. Third, repair cracks by injection, then let the substrate dry before treating surfaces. Fourth, apply the main barrier: basement waterproofing for the walls and floor, with epoxy coating at SAR 35–90 per m² where a sealed, cleanable finish suits food areas. Fifth, if the building has an internal tank, plan tank internal coating at SAR 25–60 per m². Finally, ask for a written schedule that shows which parts of the kitchen remain usable during each stage, so trading can continue.

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