Basement & foundation waterproofing in Almajmaah: the local context

Main roads in or near Almajmaah: King Abdullah Road, King Fahd Road, King Salman Road. The centre of Almajmaah sits about 720 m above sea level (SRTM open elevation data).

Team note on Almajmaah: 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 first thing a technician checks in Almajmaah is the site's height and position, because the centre of Almajmaah sits about 720 m above sea level (SRTM open elevation data). That elevation shapes how water moves across the ground and how quickly rain runs off, so a basement or foundation can be exposed to different groundwater pressure than a similar building on lower land. Before quoting, the crew looks at where surface water tends to collect around the building and whether the basement walls are below the level of the surrounding ground. This first look helps set the scope and tells the technician which waterproofing approach is likely to suit the structure.

Several points are left to the site visit, since they cannot be judged from a distance. The technician measures the wall and floor area to be treated, because basement waterproofing is priced per m² at SAR 50–150 per m², and the final figure depends on the exact surface. Cracks are assessed separately, as crack injection is charged per metre at SAR 40–120 per m. The crew also decides whether an epoxy coating (SAR 35–90 per m²), spray foam (SAR 20–45 per m²) or a boards-based system using XPS boards (SAR 12–30 per m²) fits the condition of the wall. Where water is stored, tank internal coating (SAR 25–60 per m²) is considered, and roofs are inspected to choose between liquid roof waterproofing (SAR 8–25 per m²) and bitumen membrane (SAR 15–35 per m²). Bathrooms within the same property are checked for bathroom waterproofing at SAR 15–40 per m².

To help the technician prepare, residents and expats should note any past leaks, damp patches or flooding, and say which areas of the basement or foundation are affected. Photographs of cracks, stains and water entry points are useful, along with the approximate size of each area. Knowing whether the space is used for storage, living or parking helps determine how much protection is needed. Clear access to the basement, roof and water tanks on the day of the visit allows the work to be assessed properly and the quote to reflect the real conditions on the site.

Each job ends with a written report that carries a verification code you can check on our site.

Signs worth paying attention to

• Cracks at construction joints.

Tools and methods, and when we use them

From the first visit to the report

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.
