What is specific about Riyadh for basement & foundation waterproofing

Main roads in or near Riyadh: King Fahd Road, King Abdullah Road, King Abdullah. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data).

Team note on Riyadh: 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 Riyadh sits about 637 m above sea level, on a broad plateau where the land is largely flat and the ground is dry for most of the year. For a clinic with a basement, that elevation means the site is not in a low-lying hollow where surface water collects, but water can still reach the lower floor through cracks, poorly sealed joints and seepage from the surrounding soil. Our basement and foundation waterproofing work starts from this picture: a site that is high and open still needs a sealed structure below ground, especially where clinical storage, plant rooms and patient areas must stay dry.

Each part of the service follows from these site conditions. Basement waterproofing is priced at SAR 55–160 per m², and the figure varies with the wall and slab condition found on inspection. Because the ground is dry rather than saturated, we focus on finding and sealing the specific paths water uses, such as construction joints and cracks, rather than treating the whole structure as if it were under constant pressure. Crack injection, at SAR 40–125 per metre, is often the right first step in a clinic basement, since it closes a defined defect without disturbing the working space above. Where the wider area needs protection, bitumen membrane at SAR 15–35 per m² or XPS boards at SAR 15–30 per m² can be added to form a continuous barrier against the surrounding soil.

Owners of clinics commonly avoid several mistakes that make this work fail early. They do not assume that a high, dry location makes a basement safe, and they do not delay repairs to a visible crack until staining reaches clinical rooms. They avoid choosing a coating only by its lowest unit rate, because a thin layer applied over a damp or dusty surface will peel. They also keep records of which areas were treated and with which system, so later repairs do not disturb sealed sections. Planning the work around clinic hours and sealing service ducts and drains before coating are other steps that prevent costly rework.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

Signs worth paying attention to

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

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

Where the problem usually comes from

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

Tools we use in Riyadh

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.
