Before we start: what we know about Tabuk

Team note on Tabuk: 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 Tabuk sits about 762 m above sea level (SRTM open elevation data).

The first thing checked on a basement or foundation job for an office or commercial building is the elevation and the ground around it, because the lie of the land decides where water comes from. The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data), so the technician looks at how the site slopes, whether surface runoff is directed toward the building, and where any stormwater collects against the lower walls. Water that pools against a basement wall for long periods puts far more pressure on the structure than damp soil does, so this is often the first problem to identify before any material is chosen.

Other things are left to the site visit, since they cannot be judged from a desk. The technician walks the basement or foundation to find active cracks, damp patches, efflorescence, and the condition of any existing membrane. Crack injection is priced per metre, typically SAR 40–115 per m, and the length actually needed is only known once the cracks are mapped and their movement is assessed. Similarly, the choice between epoxy coating (SAR 35–85 per m²), spray foam (SAR 25–35 per m²), XPS boards (SAR 10–30 per m²) or a bitumen membrane (SAR 15–35 per m²) depends on how wet the wall is, whether the surface is sound, and how the space will be used. Basement waterproofing as a whole usually falls within SAR 50–145 per m², but the final figure follows from what the inspection finds.

Information that helps the technician includes the basement's wall area and any sections that are below the water table or regularly flooded, the existing drainage routes, previous repairs, and any tanks or plant rooms that may need internal coating, which typically runs from SAR 25–55 per m². Details about the use of each room also matter, since offices with server equipment or archives have different tolerance for moisture than storage areas. Sharing photographs, drawings of the foundation, and a note of when leaks appear, whether after rain or during dry seasons, lets the technician plan the work accurately and reduces surprises once the job starts.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.

The most common causes

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

How we choose the tool in Tabuk

The steps in order
