Team note on Jubail: 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..

Water tank waterproofing in Jubail begins with the location itself. The centre of Jubail sits about 4 m above sea level (SRTM open elevation data), and the town is about 0.9 km from the sea coast (OpenStreetMap). Because the coast is so close, the first thing a technician checks is how the tank has been exposed to salt-laden air and to the moisture that comes with it. Salt can work into concrete and coatings over time, so the inspection focuses on the outer walls, lids and any joints where the salt would collect and remain damp. Early checks like these prevent small weaknesses from becoming leaks that are costly to repair.

Some parts of the job can only be judged on the day of the visit. The technician will decide, with the tank in front of them, whether the existing coating is still bonded, whether there are hairline cracks that need crack injection, and whether the internal surface needs a fresh tank internal coating. The depth of any damage, the condition of the tank base and the way the tank is connected to the building are all site-specific and cannot be settled from a description alone. Pricing for any repair depends on these findings, so the technician will confirm the scope only after looking at the tank directly. Where the tank sits on or against a basement structure, the state of that wall and its waterproofing will also be noted on site.

To help the technician arrive prepared, it is useful to share a few details before the visit. Tell them roughly how old the tank is, whether it has ever leaked, and whether any staining, flaking or damp patches have been seen on the walls or roof around it. Note where the tank is located, whether it is on the roof, at ground level or underground, and whether it is open to the air. Mention any previous repairs or coatings you know about, since these affect how the new layer will bond. Clear access to the tank and its lid also saves time. With this information, the visit can focus on the areas that matter most for a reliable periodic check.

Preventive checks follow a written schedule instead of waiting for a fault.
