Basement & foundation waterproofing in Aldawadmi: the local context

Team note on Aldawadmi: 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.. Main roads in or near Aldawadmi: King Abdulaziz Road, Dawadmi Bujadiyah Road.

The centre of Aldawadmi sits about 976 m above sea level (SRTM open elevation data).

Picture a restaurant owner in Aldawadmi who has leased a basement for storage and a prep kitchen. After a few heavy rains, damp patches appear on the walls, the floor smells musty, and stock stored on shelves starts to spoil. The owner wants the problem fixed before it affects food safety and the reputation of the dining room above. This is a common situation for food businesses, where a basement is valuable space but also one of the hardest areas to keep dry.

The centre of Aldawadmi sits about 976 m above sea level (SRTM open elevation data), so the ground around the town slopes and water moves across the surface after storms. Basement walls and slabs that sit below ground are constantly exposed to moisture in the soil, and any cracks or weak joints give water a route inside. For a restaurant, the choice of waterproofing matters more than usual, because the coatings and membranes must stand up to cleaning, drainage and the constant use of storage areas. Costs vary widely: basement waterproofing typically falls in the range of SAR 50–150 per m², crack injection runs SAR 40–120 per metre, and epoxy coating sits between SAR 35 and 90 per m², so a clear survey before choosing a method saves money.

Start by inspecting the basement after a rainy period and marking every damp patch, crack and water entry point. Next, confirm where water is coming from, whether through the walls, the floor joints or the drainage outside, and fix the cause before sealing the surface. Cracks should be injected first, then the main walls and slab treated with a suitable membrane or coating, with XPS boards added where insulation is also needed. Finally, check that the finished surfaces are dry for several days, keep a record of the work for your landlord and food-safety inspections, and schedule a simple re-check after the next wet season.

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