Water tank waterproofing in Sakaka: the local context

Team note on Sakaka: 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 Sakaka sits about 555 m above sea level (SRTM open elevation data).

Do I really need to empty my water tank to get it waterproofed? In Sakaka, where the centre sits about 555 m above sea level, many owners assume the answer is yes, because they expect any repair to mean draining the tank and losing a supply they depend on. The short answer is that tank waterproofing can often be handled without a full drain, and the price depends on the material and the area treated. For a tank internal coating, the typical rate is SAR 25–60 per m², while epoxy coating runs SAR 35–90 per m², so the cost depends on the surface and product chosen rather than on the tank being emptied.

Before any work starts, the inspection looks at the places where leaks usually begin. The technician checks the tank walls and floor for cracks, and where a hairline crack is found, crack injection is priced at SAR 40–120 per metre. The inspection also covers the joints and the top cover, since a leaking roof can let rainwater reach the tank. For roof areas, liquid roof waterproofing is SAR 8–25 per m², and bitumen membrane is SAR 15–35 per m². The inspector notes which surfaces are sound, which need repair, and which need a full coating, so the job is planned around what is actually found rather than a guess.

Preparation makes the visit faster and clearer. Clear the area around the tank and the access point so the technician can reach the walls, the lid, and the roof. Note any past leaks, damp patches, or repairs, and keep the date of the last cleaning if you have it. Tell the crew how the tank is fed and when water is needed, so the schedule can avoid the times you rely on it most. If the tank is part of a wider project, such as a basement, the scope can be discussed in advance, since basement waterproofing is SAR 50–150 per m² and is priced separately from tank work.

The aim is to locate the cause with instruments first, so any opening is limited to one point.
