What is specific about Almajardah for floor & balcony waterproofing

Team note on Almajardah: 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 Almajardah sits about 2035 m above sea level (SRTM open elevation data).

The first thing checked on a floor or balcony job in an office or commercial complex is the elevation and exposure of the building, because these shape how the membrane behaves over time. The centre of Almajardah sits about 2035 m above sea level (SRTM open elevation data), so the technician looks at how much sun, wind and temperature swing the surface will take before choosing a system. Balconies and open terraces face the most direct exposure, so the first questions are about slope, drainage outlets, and whether standing water would sit on the slab after rain.

Several points are left for the site visit, because they cannot be judged from a desk. The technician walks the slab to find cracks, blistering, old coatings that are lifting, and any place where a crack needs crack injection priced per metre rather than per square metre. Costs from the reference range vary by system: liquid roof waterproofing runs SAR 8–25 per m², bitumen membrane SAR 15–35 per m², spray foam SAR 20–45 per m², and epoxy coating SAR 35–90 per m², so the surface condition decides which of these is realistic. Basement-level or below-grade floors would fall under a different rate band, such as basement waterproofing at SAR 50–150 per m², so the technician confirms exactly which areas are being treated before anything is quoted.

To help the technician prepare, it is useful to have the floor plan with balcony and terrace areas marked, any previous waterproofing records, and a note of where water has been seen inside the building. Indicate whether the space is a bathroom or wet area, since bathroom waterproofing is priced separately at SAR 15–40 per m², and note whether any tanks are involved, as tank internal coating is SAR 25–60 per m². Insulation work, if the balcony needs it, is usually handled with XPS boards at SAR 12–30 per m², so flag that early. Clear information at this stage lets the visit focus on the slab itself rather than on questions that could have been answered beforehand.

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