Why basement & foundation waterproofing differs in Turaif

The centre of Turaif sits about 827 m above sea level (SRTM open elevation data).

Turaif sits at the northern edge of the Kingdom, in the Northern Borders Province, and the centre of the town is about 827 m above sea level. That height means the town is set on higher ground than much of the surrounding land, so clinics here are often built on sloped plots where rainwater runs downhill and gathers against basement walls. For a clinic with a basement for storage, plant rooms or records, this matters because water pressure builds at the lowest points of the structure, not at the surface. Our basement and foundation waterproofing work starts with that slope in mind, so the membrane and drainage details are planned around where water will actually travel.

Each fact shapes the way the work is priced and carried out. Because basement waterproofing ranges from SAR 50–150 per m², the final figure depends on how much wall and floor area is exposed to ground water, and on whether the work includes new membrane or repair of an existing one. Crack injection, priced at SAR 40–120 per metre, is often the first step where older clinic basements show hairline or stepped cracks, since sealing these before applying a full coating prevents leaks from returning through the same line. Where a clinic has a bathroom or treatment room above or beside the basement, bathroom waterproofing at SAR 15–40 per m² and epoxy coating at SAR 35–90 per m² are used to protect floors and wet areas that drain into the same structure. Spray foam at SAR 20–45 per m² and XPS boards at SAR 12–30 per m² are chosen for insulation and moisture control where the wall build-up allows them, and liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m² cover the roof slab that drains onto the foundation.

Clinic owners in Turaif tend to avoid several common mistakes that we see on site. The first is treating a basement leak as a surface problem and painting over damp patches without sealing the source. The second is ignoring the roof and drainage above the foundation, so the slab keeps feeding water into the walls below. The third is delaying repair of a single crack until it spreads, which raises the cost of crack injection and the area that must be coated. The fourth is choosing a cheap coating for a tank or wet room without checking that it suits the water it will hold. Planning these points early keeps the clinic dry, the work to a sensible scope, and the building usable without interruption.

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

Signs worth paying attention to

The following signs are worth checking before they grow:

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

Where the problem usually comes from

• A common cause: cracks at construction joints.
• A high groundwater level.
• Rainwater draining towards the foundation — 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.
