Water tank waterproofing in Madinah: the local context

Team note on Madinah: 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 Madinah sits about 589 m above sea level (SRTM open elevation data).

The first thing checked on a water tank job in Madinah is the tank itself and where it sits, because the centre of the city lies about 589 m above sea level (SRTM open elevation data). That altitude matters for how water is delivered and stored on rooftops and in ground-level tanks alike, so the technician records the tank's position, access route, and whether it is fed by pumps or gravity. Before any product is chosen, the surface is inspected for existing coatings, flaking, efflorescence and hairline cracks. Crack injection is priced per metre, at SAR 40–120 per m, so measuring the length of visible cracks early gives the client a clear picture of the likely scope and cost range before work starts.

Several points are left to the on-site visit, because they cannot be judged from a desk. The technician confirms the tank's material, its internal dimensions and the surface area that needs covering, since internal tank coating is priced at SAR 25–60 per m². They also check whether the tank is a shared or stand-alone structure, whether a basement or bathroom is connected to the same water system, and whether the roof above it needs liquid waterproofing (SAR 10–25 per m²) or a bitumen membrane (SAR 15–35 per m²). Choosing between epoxy coating (SAR 35–90 per m²) and spray foam (SAR 20–45 per m²) depends on the condition of the substrate, which only becomes clear once the surface is opened up and dried. Where insulation is involved, XPS boards (SAR 10–30 per m²) are assessed in place rather than assumed.

To help the technician, the client should prepare a simple site note before the visit: the tank's location, its approximate size, the date water was last drained, any leaks noticed, and photos of cracks or staining. Access to the roof, the tank lid and the plant room should be arranged in advance, and the building's operating hours should be confirmed so that the tank can be emptied and dried safely. Recording which areas are basement, bathroom or roof helps match the right rate card to each part of the job. With this information ready, the technician can arrive, measure, and give an accurate scope, leaving the office team free to present clear options to the client.

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