Basement & foundation waterproofing in Almikhwah: the local context

The centre of Almikhwah sits about 419 m above sea level (SRTM open elevation data).

Almikhwah sits about 419 m above sea level, which is the first fact a technician weighs when looking at a basement or foundation problem in this area. Elevation shapes how groundwater and rainwater move around a building, so the first checks focus on where water is likely to press against the lower walls and floor slab. Before any product is chosen, the visit starts by confirming whether the basement is wet from the outside, from cracks, or from condensation inside, because each cause points to a different waterproofing route.

Several things are left to the site visit rather than settled from a distance. The technician needs to see the actual condition of the walls and slab, measure the affected area in square metres, and locate any cracks and their length in metres. Crack injection is priced per metre and wall waterproofing per square metre, so these measurements decide which lines of the price guide apply. Basement waterproofing typically falls within SAR 50–150 per m², while epoxy coating ranges from SAR 35–90 per m² and spray foam from SAR 20–45 per m². Crack injection costs SAR 40–120 per m. Which of these suits the wall, and how much of it is needed, can only be judged once the site is open for inspection.

Some information helps the technician prepare and reduces surprises. It is useful to know when water appears, whether after rain, during irrigation, or all year, and whether the basement is used for storage, living space, or plant. Any previous repairs, visible staining, or an existing membrane should be pointed out. If a water tank sits in or near the basement, its internal coating is priced separately at SAR 25–60 per m², so mention it at the start. Clear access to the basement and to the areas above it also saves time on the day of the visit.
