Before we start: what we know about Hafr Albatin

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 centre of Hafr Albatin sits about 312 m above sea level (SRTM open elevation data).

Hafr Albatin sits about 312 m above sea level, so the centre of town is a plain-to-gently-rising inland setting rather than a coastal one. For a restaurant owner, that matters less for salt air and more for how rain and runoff behave on a site. Water that falls on hard surfaces and roofs tends to move quickly toward the lowest point nearby, so floors and balconies that drain poorly will hold water for longer. Our floor and balcony work is planned around that movement, with attention to falls, drainage outlets and the joints where a wet kitchen floor meets a dining area.

Each element of a restaurant site responds to water differently, and the pricing we set out reflects that. Liquid roof waterproofing is priced at SAR 8–25 per m², which suits open rooftop and balcony areas that need a seamless skin. Bitumen membrane, at SAR 15–35 per m², is a sheet-based option for surfaces that take regular foot traffic. Where a leak has already started through a slab, crack injection at SAR 40–120 per metre stops water at the source, and epoxy coating at SAR 35–90 per m² gives kitchen and service floors a sealed, wipeable finish that can handle grease and cleaning. Spray foam, at SAR 20–45 per m², is useful where insulation and waterproofing are needed together. Each option is chosen to match how the space is used, not simply the cheapest line on the list.

Owners who keep their floors and balconies dry tend to avoid a few common errors. They do not paint over a damp or cracked surface and expect the problem to stay hidden, because moisture then pushes through the new layer. They do not skip the drainage check, since a membrane laid over a poor fall simply keeps the puddle in place. They also avoid treating a rooftop, a balcony and a basement as one job; each carries different loads and exposure, and basement waterproofing at SAR 50–150 per m² or a tank lining at SAR 25–60 per m² needs its own method. Finally, they do not delay repairs until a ceiling stains below, because by then the damage has usually spread beyond the first patch.

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

Tools and methods, and when we use them

From the first visit to the report

1. Checking the falls: Where water collects and where it should go.
2. Details: Thresholds, drains and upstands.
3. Waterproofing: The layer is applied and protected.
4. Flood test: Tested before the finish goes on.
