Does a restaurant basement in Sharurah really need waterproofing, given that the town is not on the coast? Sharurah sits at high ground, with the centre about 724 m above sea level (SRTM open elevation data), so the wet-season runoff that moves through a site is the main concern rather than flooding from the sea. Water still finds its way into any below-grade kitchen store, prep room or cold storage space through cracks, poor drainage and ground moisture, and for a restaurant that damage can ruin stock, equipment and the health standard of the room. Waterproofing a basement is priced at SAR 50–150 per m², and the right method depends on what is actually letting the water in.

A proper visit starts with the walls and floor of the basement, looking for active leaks, damp patches and hairline or wider cracks. Where a crack is found, the price for crack injection runs SAR 40–120 per metre, so the inspector measures the length of each crack to give an accurate figure. The inspection then checks the surfaces that will receive the treatment: epoxy coating is priced at SAR 35–90 per m², spray foam at SAR 20–45 per m², and a bitumen membrane at SAR 15–35 per m², and the choice between them depends on the condition of the substrate and how the room is used. Any water storage tank on the premises is also checked, since internal tank coating costs SAR 25–60 per m² and is often done alongside the basement work. Roof areas above the kitchen are reviewed separately, with liquid roof waterproofing at SAR 8–25 per m².

Before the visit, the owner should clear access to the basement walls and floor, and move stock, shelving and equipment away from the areas to be checked. It helps to have any earlier repair records, notes on when water was last seen, and a rough sketch of the basement and roof dimensions, so the measurements can be taken quickly. If the site has a tank, make sure it can be reached and, where possible, emptied for inspection. Note the times the leaks appear, such as after rain, so the inspector can trace the source. With these details ready, the visit can focus on the real problem and produce a clear scope of work for the restaurant.

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

Tools and methods, and when we use them

How the work is done, step by step

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.
