Before we start: what we know about Tarout

Main roads in or near Tarout: Uhud Road, Al Khaleej Road, Al Aimmah Bridge. Team note on Tarout: 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..

Tarout is about 0.9 km from the sea coast (OpenStreetMap). The centre of Tarout sits about 3 m above sea level (SRTM open elevation data).

A rest house or farm in Tarout is often used on weekends and holidays, sometimes for long stretches with no one on site. The owner may have a bathroom at the back of the property, a small tank on the roof, and a floor that gets splashed daily by families and guests. When water finds a weak point, the damage is usually hidden behind tiles and walls until a patch of paint bubbles or a smell appears, by which time the plaster and fixtures behind it may already be affected.

The local facts shape how you should plan this work. The centre of Tarout sits about 3 m above sea level, and the town is about 0.9 km from the sea coast. That combination means the ground is low, moisture-laden air is common, and salt can work its way into masonry over time. A bathroom that looks dry on the surface may still be drawing damp from below, so the waterproofing should be treated as part of the structure rather than a cosmetic touch-up. For a typical bathroom, the cost of membrane or coating work is quoted at SAR 15–40 per m², while epoxy coating runs SAR 35–90 per m², so the choice of system depends on how much wear the room will take and how often it is used.

Start by inspecting the bathroom floor, walls and the junction with the shower tray, looking for hairline cracks, lifted tiles and staining. Mark every crack, because crack injection is priced separately at SAR 40–120 per metre and should be handled before any coating goes on. Next, clear the surface, let it dry fully, and repair any damaged plaster. Choose the waterproofing system that suits the room, then apply it in the number of coats the product requires, extending it up the walls at the shower zone. If the roof tank or the roof is part of the problem, liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² can be considered, and an internal tank coating at SAR 25–60 per m² protects stored water. Finish by testing the bathroom with a short run of water before tiling, and keep a record of the work for future maintenance.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.
