Why basement & foundation waterproofing differs in Aldiriyah

Team note on Aldiriyah: 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 Aldiriyah sits about 655 m above sea level (SRTM open elevation data).

Basement and foundation leaks are the most common problem we see in restaurants, because kitchen floor drains, grease traps, cold rooms and storage areas often sit below ground level, where water pressure builds against the walls and slab. Cracks in the foundation and damp patches on lower walls usually appear first, and they tend to get worse during wet seasons when rainwater and groundwater rise. Left alone, they can damage stock, equipment and the health approvals a restaurant depends on.

Aldiriyah changes how the work should be approached. The centre of Aldiriyah sits about 655 m above sea level, so ground conditions and drainage patterns here are not the same as in low-lying coastal areas, and a sound plan starts with a site-specific look at how water moves toward the basement. For a restaurant, the choice of system matters as much as the cost. Basement waterproofing is priced at SAR 50–150 per m², crack injection at SAR 40–120 per metre, and epoxy coating at SAR 35–90 per m², so the right combination depends on whether the problem is a single crack, a damp wall, or a wider area that needs a continuous barrier. Where a kitchen or washing area is involved, bathroom-grade waterproofing at SAR 15–40 per m² and bitumen membrane at SAR 15–35 per m² may also be relevant to protect adjoining spaces.

Before the visit, ask the contractor to explain how they will find the source of the water rather than only sealing the surface, and whether they will check drains and the slab edge as part of the inspection. Ask which materials they propose and why, and request a written breakdown by area and by method so you can compare figures against the ranges above. Confirm when the work can be done without closing the kitchen during peak service, and ask how long the area must stay out of use afterwards. A clear answer to these questions will show whether the team understands restaurant basements.

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