Why water tank waterproofing differs in Jubail

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.. Jubail is about 0.9 km from the sea coast (OpenStreetMap).

The centre of Jubail sits about 4 m above sea level (SRTM open elevation data).

Jubail is a coastal city, and its centre sits about 4 m above sea level, while the sea coast is about 0.9 km away. For a water tank, that closeness matters: salt-laden air and groundwater near the coast can affect how coatings bond and how long they last, so the first check is the tank's exposed surfaces and the condition of the existing lining. Technicians should look at whether the tank is on a roof, at ground level, or partly buried, because each position changes how water pressure and sun exposure act on the walls and base.

Some things can only be judged at the site visit. These include the depth of any cracks, whether the old coating is lifting or flaking, the presence of salt crystals or rust staining on the steel, and whether water is entering from the base, the seams or the fittings. The technician will also confirm the tank's material, its size and the access available for work and for drying time. Pricing for tank internal coating in this area falls within SAR 25–60 per m², but the final scope depends on what is found once the surface is open and cleaned, so no figure should be treated as fixed before inspection.

For the technician, the practical points are these. Note the exact location of every leak path before choosing a method, since crack injection is charged per metre (SAR 40–120 per m) and is used for narrow defects, while a full internal coating is charged per square metre. Record whether the tank holds drinking water, because that affects the choice of product and the cleaning steps. Photograph the surfaces before and after cleaning so the scope is clear to the client, and confirm the curing requirements of the chosen system before the tank is refilled.

Each job ends with a written report that carries a verification code you can check on our site.
