Before we start: what we know about Sabya

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 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).

Water tanks in Sabya need checking first for signs that water is getting through the walls or base, and the local setting explains why. The centre of Sabya sits about 40 m above sea level (SRTM open elevation data), so the town is not at the coastal level, but it is still only about 16.7 km from the sea coast (OpenStreetMap). A technician will therefore look first at salt staining, flaking coating, and damp patches along the seams, because these point to moisture working into the concrete. Start by noting when the tank was last inspected or coated, whether the water level drops faster than usual, and whether there are any visible cracks.

Some points can only be settled during the site visit. The technician will need to see the tank itself to judge whether the damage is surface-level or deeper, and whether a repair such as crack injection or a full internal coating is the right choice. Crack injection is priced at SAR 40–120 per metre, while tank internal coating is SAR 25–60 per m², so the scope of the work changes the cost considerably. The visit is also the time to check the access, the water quality, and whether the tank must be drained before work starts. Nothing in the price ranges should be taken as a quote, because the final figure depends on what the inspection finds.

To help the technician, have information ready before the visit. Record the tank's approximate size, its age, the type of lining or coating already in place, and any previous repair work. Note whether the tank is roof-mounted or at ground level, since this changes access and the materials considered. If you can, take clear photographs of any cracks, stains, or peeling areas and show where the leaks appear. Tell the technician about any recent works on the building, such as new plumbing or changes to the roof, as these can affect how the tank behaves. Clear details at the start make the visit quicker and the advice more precise.

Some signs can be watched for a few days; others need a technician straight away — the signs list above helps you decide.
