What is specific about Sharurah for basement & foundation waterproofing

Team note on Sharurah: 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 Sharurah sits about 724 m above sea level (SRTM open elevation data).

Main roads in or near Sharurah: King Abdulaziz Road, King Fahd Road.

Basement and foundation waterproofing in Sharurah most often starts with water finding its way through cracks and cold joints in the lower walls and floor slab. Companies that run offices, stores or storage areas below ground tend to notice damp patches, efflorescence on concrete, and a musty smell long before the damage is structural. Before any work is quoted, the first question is usually where the water is entering, because a surface coating on the wrong part of the wall will not stop a leak that comes through a crack.

Sharurah sits at about 724 m above sea level, which shapes how the job is approached. At that height the town is well above the coast, so the water pressure on a basement wall comes mainly from groundwater and surface runoff after rain rather than from a high water table. A survey should therefore look at how rainwater drains away from the building, the condition of external ground levels, and whether gutters and downpipes discharge close to the foundation. Crack injection is typically priced per metre, at SAR 40–120 per m, and is often the first step where cracks are the visible cause. Basement waterproofing itself is priced at SAR 50–150 per m², and the choice between an epoxy coating at SAR 35–90 per m², a spray foam at SAR 20–45 per m², or insulated XPS boards at SAR 12–30 per m² depends on how the wall is exposed and how the space will be used afterwards.

Before a site visit, companies should ask the contractor to confirm the area in square metres and the length of visible cracks in metres, so that the estimate matches the real scope. It helps to share any previous repair records, photographs of the damp areas taken after rain, and details of how the space is used, such as storage of stock or equipment that cannot be exposed to moisture. Ask which method is proposed for each part of the basement, why it was chosen, and how the work will be carried out without stopping daily operations. A clear written scope, with each item priced separately, makes it easier to compare proposals and to plan the work around business needs.

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

Tools and methods, and when we use them

From the first visit to the report

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.
