Water tank waterproofing in Sharurah: the local context

Team note on Sharurah: 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 Sharurah sits about 724 m above sea level (SRTM open elevation data).

Main roads in or near Sharurah: King Abdulaziz Road, King Fahd Road.

Before any work starts on a water tank at a warehouse in Sharurah, the first thing checked is the setting itself. The centre of Sharurah sits about 724 m above sea level (SRTM open elevation data), which means the site is on high ground in the Najran region. For a tank that holds water for a large building, that matters: the technician looks at how the tank sits on its base, whether runoff from rain could collect against its walls, and whether the existing coating has been weakened by long exposure to sun and heat. The aim is to establish what is actually failing before any product is chosen.

Some decisions cannot be made from a desk. The condition of the tank walls, the extent of any cracks, the state of the old lining, and the access available inside the tank are all judged at the site visit. Cracks are measured on the spot, because crack injection is priced per metre and the length found on the day decides the scope. The same applies to the internal surface area, since tank internal coating is priced per square metre and the true area can only be confirmed once the tank is inspected. Whether the tank needs a full re-coat or only local repairs is also a site decision, and the technician will say so after looking at the surfaces.

Information that helps the technician is simple and worth gathering before the visit. Note the tank's approximate dimensions, what the tank was last coated with if known, and any places where water has been seen leaking or staining. Mention whether the warehouse has other waterproofed areas nearby, such as roof sections or a basement, since these can share the same water source and may need to be quoted together. For reference, prices in this area typically run as follows: tank internal coating at SAR 25–60 per m², epoxy coating at SAR 35–90 per m², and crack injection at SAR 40–120 per metre. A clear record of the tank and its history lets the technician give a firm quote without guesswork.

For warehouses, work is phased around operations and stored goods.

Signs worth paying attention to

These are the signs most often linked to water tank waterproofing:
