Before we start: what we know about Riyadh

Main roads in or near Riyadh: King Fahd Road, King Abdullah Road, King Abdullah. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data).

Team note on Riyadh: 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 Riyadh sits about 637 m above sea level, and that elevation shapes how we start a damp assessment for a restaurant. Before any quote is given, the technician looks at the walls that touch the ground and the spaces that are most exposed to moisture, such as the kitchen wash area, cold rooms, and any basement store. Those are the places where water is most likely to enter, and they are where the work is measured. Pricing for this kind of job is set per square metre or per metre of crack, so the first step is to establish which surfaces are actually affected and how large they are. Basement waterproofing typically falls in the range of SAR 55–160 per m², while crack injection is priced at SAR 40–125 per metre, so accurate measurement at the outset keeps the estimate clear.

Several things cannot be judged from a description or a photograph and are left to the site visit. The technician will need to see how the damp moves through the wall, whether it rises from the floor, comes through a joint, or runs down from a roof or a neighbouring tank. They will check the condition of the render, the state of any existing coating such as epoxy, which is priced at SAR 35–95 per m², and whether spray foam at SAR 20–45 per m² or XPS boards at SAR 15–30 per m² would suit the space. Ventilation, drainage outside the building, and the working hours a restaurant can allow for a clean-up are also confirmed on the day. Nothing is recommended until these points have been seen in person.

Information that helps the technician is simple to gather in advance. Note which walls feel damp, when the staining appears, and whether it worsens after cleaning or heavy use of water. If the premises include a water storage tank, mention whether it is accessible, as internal tank coating is priced at SAR 25–65 per m². Bathroom and toilet areas, where waterproofing is priced at SAR 15–40 per m², should be flagged separately, and any roof leaks should be described along with where they show inside. Clear answers to these questions let the visit focus on the real source of the problem.

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