What is specific about Alzulfi for basement & foundation waterproofing

Team note on Alzulfi: 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 Alzulfi: King Fahd Road, Sheikh Ibn Baz Square, King Salman Road.

The centre of Alzulfi sits about 615 m above sea level (SRTM open elevation data).

Alzulfi sits at roughly 615 m above sea level, and that elevation is the first thing we check when a basement or foundation problem is reported. Ground that sits on a rise drains differently from a low-lying plot, so the technician begins by looking at where water is likely to arrive from and where it will run to. Basement waterproofing in the area is priced from SAR 50–150 per m², and that range reflects how much of the wall and floor area is exposed to ground moisture, so the first measurement taken on site is the total wetted surface that needs treatment.

Several items are left to the site visit because they cannot be judged from a description. The technician walks the perimeter, notes the state of any cracks and how far they run, and decides whether crack injection at SAR 40–120 per metre is needed in addition to the wall treatment. Epoxy coating at SAR 35–90 per m² or spray foam at SAR 20–45 per m² may suit different surfaces, and the choice depends on the substrate, the moisture already present and how the space is used. Bitumen membrane at SAR 15–35 per m² and XPS boards at SAR 12–30 per m² are options that the technician weighs against access, headroom and the timing of any other works. Where the basement holds water storage, tank internal coating at SAR 25–60 per m² is considered separately from the structure around it.

To help the technician arrive prepared, it is useful to tell us when the damp first appeared, whether it follows heavy rain or is constant, and which walls or corners are affected. Photographs of staining and any visible cracks, along with a rough sketch of the basement dimensions, let the visit focus on the problem rather than on measurement. Note whether the space is finished, stored with goods, or used as living area, since this changes the access and the protection needed during works. Information about nearby bathrooms or roof drainage is also welcome, because damp often travels from these sources. With these details in hand, the technician can confirm the scope on the first visit and give a clear estimate based on the rates above.

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

• Rainwater draining towards the foundation.

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.
