Why basement & foundation waterproofing differs in Madinah

The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Team note on Madinah: 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..

Madinah's city centre sits about 589 m above sea level, according to SRTM open elevation data. For companies that own or operate buildings with basements and foundations here, this elevation shapes the work in practical ways. Sites in an inland, elevated setting still face groundwater, seasonal rainfall runoff and the moisture that rises through concrete, so a waterproofing plan has to start with how water actually reaches the structure rather than assuming the site is dry because it is high.

Each service in this range answers a specific problem. Basement waterproofing is priced from SAR 50 to SAR 150 per m², and it is the main protection for below-grade walls and slabs where water pressure builds against the structure. Crack injection, priced at SAR 40 to SAR 120 per metre, targets the visible openings that let water track inward, and it is usually the first step before a wider membrane or coating goes on. Epoxy coating, at SAR 35 to SAR 90 per m², suits interior floors and walls that need a sealed, cleanable surface, while tank internal coating, at SAR 25 to SAR 60 per m², protects water storage from the inside. Liquid roof waterproofing, at SAR 10 to SAR 25 per m², and bitumen membrane, at SAR 15 to SAR 35 per m², cover roofs and exposed decks where drainage and surface sealing matter most. XPS boards, at SAR 10 to SAR 30 per m², add insulation and drainage behind walls, and spray foam, at SAR 20 to SAR 45 per m², fills gaps and joints quickly across larger areas.

Company owners who manage several sites tend to avoid a few predictable errors. They do not treat a basement as a single surface, so they budget separately for walls, slabs and crack repairs instead of applying one coating everywhere. They do not skip crack injection and then expect a membrane to hold, because water finds the old opening. They do not compare quotes by the lowest per-metre figure alone, since a cheap rate on a poorly prepared surface often means repeat work. And they do not leave bathrooms, tanks and roofs out of the same review, because moisture that starts in one area frequently travels into the next.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

Signs worth paying attention to

If you notice one of these signs in Madinah, 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.

Tools and methods, and when we use them

The steps in order

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.
