What is specific about Aldiriyah for water tank waterproofing

The centre of Aldiriyah sits about 655 m above sea level (SRTM open elevation data). Team note on Aldiriyah: 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 Aldiriyah starts with the ground under the tank and the tank's own shell. The centre of Aldiriyah sits about 655 m above sea level (SRTM open elevation data), which tells a technician that the local ground and water supply conditions should be looked at before any coating is chosen. In practice, the first checks are whether the tank has visible cracks, whether the internal surface is flaking or stained, and whether any water is already seeping through the walls or base. Tank internal coating is priced at SAR 25–60 per m², so the size of the internal surface is one of the first things that shapes the quote.

Some points can only be settled at the site visit. The technician needs to see the actual condition of the tank, measure the surface area, and judge whether crack injection is needed. Crack injection is priced at SAR 40–120 per metre, so the length of visible cracks matters. The choice between epoxy coating at SAR 35–90 per m² and spray foam at SAR 20–45 per m² depends on what the surface is made of and how it has been treated before. These decisions should be made on the spot rather than from a distance, because the same tank can look sound from outside and still need repair inside.

For the technician, the most useful information is a clear record of the tank's dimensions, its material, how old it is, and any previous repairs or coatings. Notes on whether the tank sits at ground level or on a roof also help, since rooftop work is priced differently, with liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m². Recording any past leaks, their location, and the water source makes it easier to plan the work and avoid repeat visits. The published ranges above are a starting guide, and the final figure depends on what the inspection finds.
