Basement & foundation waterproofing in Alqurayyat: the local context

Team note on Alqurayyat: 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 Alqurayyat sits about 497 m above sea level (SRTM open elevation data).

Basement and foundation leaks in rest houses and farms usually begin at the joints where the floor meets the wall, and at hairline cracks that open up as the ground shifts after rain. In Alqurayyat, the centre sits about 497 m above sea level, which is high enough that a good deal of rainfall runs off the slopes rather than pooling for long. That still leaves water finding its way into lower rooms and stores through soil that is already saturated after a storm, so the leak often shows up days after the weather has cleared.

Because the town is elevated and the land drains quickly, the approach here focuses on sealing the path water takes into the structure. Crack injection is priced at SAR 40–120 per metre, so a short, clearly traced crack is often the first job, and it can be treated before any wider surface work begins. Where the whole basement wall needs protection, basement waterproofing runs at SAR 50–150 per m², and a bitumen membrane at SAR 15–35 per m² or XPS boards at SAR 12–30 per m² may be used depending on how the wall is exposed. For farm storage tanks, tank internal coating at SAR 25–60 per m² is the usual route. Each option suits a different condition, which is why the survey comes first.

Before the visit, ask the provider to confirm which areas will be measured and whether the quote is per square metre or per metre of crack, since the rates differ widely. Ask how they will locate the source of the water, whether they will test after rain, and what preparation is needed from you, such as clearing stored items from the lower room. Ask too whether the price covers both the materials and the labour, and whether any works inside the tank or basement will be done while it is empty. A clear written scope before work begins makes the final result easier to judge.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs that call for basement & foundation waterproofing

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

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