Before we start: what we know about Wadi Aldawasir

The centre of Wadi Aldawasir sits about 683 m above sea level (SRTM open elevation data).

Wadi Aldawasir sits high in the Najd region, with the centre about 683 m above sea level (SRTM open elevation data). For restaurant owners, that elevation shapes how water behaves around a building. Rain runs off slopes quickly, and the ground can hold moisture in pockets where the land dips, so a basement or lower floor is more exposed to water pressure from the surrounding soil than the height alone might suggest. A restaurant with a kitchen, storage room or cold room below ground needs a waterproofing plan that deals with that pressure from the start.

Because of this, the first step on any restaurant site here is a survey of the basement and foundation walls, followed by a choice of system matched to the specific risk. Basement waterproofing is priced at SAR 50–150 per m², and crack injection is priced at SAR 40–120 per metre, so repairing visible cracks is often a sensible early step before a full membrane goes in. Kitchen and washroom areas, which see daily water use, can be treated with bathroom waterproofing at SAR 15–40 per m², while epoxy coating at SAR 35–90 per m² suits floors that must stay clean and easy to wash. Spray foam at SAR 20–45 per m² is another option where a fast, seamless layer is needed. For roofs above dining rooms, liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² can keep leaks away from ceilings and equipment. Water storage for the kitchen is covered by tank internal coating at SAR 25–60 per m², and insulation boards such as XPS boards at SAR 12–30 per m² help protect walls from moisture and temperature change.

Owners who work with these systems tend to avoid several common errors. They do not skip the crack repair and simply paint over damp walls, since the water will find its way through again. They do not choose the cheapest coating without checking how it will hold up under daily washing and heavy foot traffic in a commercial kitchen. They do not leave the roof and basement planned separately, because water that enters one area often travels to the other. They also avoid waiting until a leak reaches stock or equipment before acting, and they keep a record of each treated area so future work can be scheduled without guesswork. Careful planning at the start is what keeps a restaurant dry, clean and open during the busiest hours.

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

Tools we use in Wadi Aldawasir

The steps in order

1. Finding the source: Groundwater, rain or a pipe — each needs a different treatment.
2. Preparation: Surfaces are cleaned and opened where needed.
3. Injection: Active cracks are injected.
4. Waterproofing layers: The system is applied on the right side of the wall where possible.
5. Follow-up: Readings are repeated after the treatment.
