Why water tank waterproofing differs in Sabya

Sabya is about 16.7 km from the sea coast (OpenStreetMap). The centre of Sabya sits about 40 m above sea level (SRTM open elevation data).

Main roads in or near Sabya: King Fahd Road, King Abdulaziz Road, King Abdullah bin Abdulaziz Road. Team note on Sabya: 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..

Sabya sits about 40 m above sea level, and its centre is roughly 16.7 km from the coast. For a company water tank, that means the first checks are about the tank itself and how water is held and drained, rather than sea-related exposure. Because the town is inland and elevated, the technician begins with the condition of the tank's internal surfaces, the joints where walls meet the base, and any visible cracks or lifting coating. Tank internal coating is priced at SAR 25–60 per m², and crack injection at SAR 40–120 per metre, so the extent of any damage shapes which work is recommended. Under an annual contract, this first inspection establishes a baseline so later visits can show whether the tank is holding up.

Some things can only be judged on site. The actual size of the tank, its access points, the age of the existing lining, whether the water is drinking-grade, and whether the tank has been drained in the past all change the scope and method. The technician also decides whether a surface needs epoxy coating (SAR 35–90 per m²) or a different system, and whether any roof or base areas connected to the tank need liquid roof waterproofing (SAR 8–25 per m²) or bitumen membrane (SAR 15–35 per m²). These decisions depend on what is seen in person, so no fixed scope is promised before the visit.

To help the technician prepare, the site contact should note the tank's approximate dimensions, its location, when it was last serviced, and any leaks or staining that have been noticed. Photographs of cracks, damp patches and the tank's access hatch are useful. Please also confirm how the tank is used, whether it feeds a kitchen, washrooms or cooling equipment, and when the building is least busy so that draining and drying can be planned. Clear answers to these points let the technician arrive ready, shorten the time the tank is out of service, and keep the annual contract schedule on track.

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