Why water tank waterproofing differs in Afif

Team note on Afif: 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 Afif sits about 1040 m above sea level (SRTM open elevation data).

Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

Before any work starts on a warehouse water tank in Afif, the technician checks the tank's position and exposure first. The centre of Afif sits about 1040 m above sea level (SRTM open elevation data), which means the site is in a highland setting where temperature swings between day and night can be pronounced. Those swings stress coatings and joints, so the first check is whether the tank is exposed to direct sun, wind, or shade, and whether the surface beneath it is level and sound. A tank that stands on an uneven or cracked base will move the coating out of shape, so the base is inspected before any product is selected.

Several points can only be settled at the site visit. The technician needs to measure the true internal and external surface area, note any existing cracks and their length, and judge whether a crack will be treated by injection or by surface coating. Access matters too: a warehouse tank may sit beside stored goods, loading bays, or vehicle routes, and these affect when and how the work can be done. The condition of the old coating, whether it is flaking, bubbling, or intact, decides whether it must be removed or can be overcoated. The water currently in the tank and its use should also be confirmed, because the choice of coating depends on whether the tank holds potable supply or process water.

To help the technician prepare, the client should provide the tank's age, its material, and any previous repair records, along with a rough sketch of its dimensions and the access route for materials. Note any recent leaks, damp patches on nearby walls, or changes in water level that could signal a hidden fault. For reference, internal coating for tanks is priced at SAR 25–60 per m², epoxy coating at SAR 35–90 per m², and crack injection at SAR 40–120 per metre, so measuring cracks and surface area accurately at the outset gives a clearer estimate. Clear information at this stage shortens the visit and keeps the eventual quotation tied to the real condition of the tank.

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

Signs worth paying attention to
