Basement & foundation waterproofing in Ahad Rafida: the local context

Team note on Ahad Rafida: 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 Ahad Rafida sits about 2055 m above sea level (SRTM open elevation data).

Ahad Rafida sits at high altitude, with the centre about 2055 m above sea level according to SRTM open elevation data. That elevation shapes the local climate and terrain, and it matters for any work below ground. Water moves across sloped ground and collects around foundations in ways that flat-land sites do not experience, so a basement here can face pressure from runoff as well as groundwater. Our survey starts with the slope and drainage paths around the building before any coating is chosen.

Because of that height and terrain, the work is priced and planned by the square metre and by the metre of crack. Basement waterproofing is quoted at SAR 50–150 per m², and crack injection at SAR 40–120 per m. Where a wall shows a linear leak, we treat the crack as its own line item rather than folding it into the whole surface, so the owner can see exactly where the money goes. Epoxy coating at SAR 35–90 per m² and spray foam at SAR 20–45 per m² are offered as options for different wall conditions, and the choice follows what the survey finds rather than a single default product.

Owners in Ahad Rafida often avoid the same problems. The first is waiting for a visible leak before acting, when moisture has already reached the wall behind finishes. The second is treating a crack without checking the drainage that feeds it, so water simply finds the next weak point. The third is comparing quotes only by the lowest rate per m², without asking what surface preparation is included. Roof and tank work follow the same logic: liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and tank internal coating at SAR 25–60 per m² each depend on clean, dry substrate. Asking what is covered before signing keeps the job honest.

The aim is to locate the cause with instruments first, so any opening is limited to one point.

Signs that call for basement & foundation waterproofing

If you notice one of these signs in Ahad Rafida, it is a good moment to talk to the team:

• Water seeping in after rain
• Damp basement walls
• Salt marks at the bottom of the walls

The most common causes

• Cracks at construction joints.
• Rainwater draining towards the foundation — we check this before anything else.
• A high groundwater level — we check this before anything else.

Tools and methods, and when we use them

How the work is done, step by step

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.
