Does a leaking water tank in Zhra Lbn need urgent attention, and what can an owner expect when a waterproofing team arrives? A tank that is seeping, cracked or showing damp patches should not be left to worsen, especially when water is needed daily. Zhra Lbn sits at about 747 m above sea level, and its centre is roughly 15.3 km from the centre of Riyadh, within an approximate radius of 8 km. The nearest wadi channel lies about 1.8 km from the centre of the district, so owners here should watch for moisture after heavy rain. Tank internal coating is priced at SAR 25–65 per m², and crack injection at SAR 40–125 per metre, so the scope of work depends on what the inspection finds.

The inspection starts with a visual check of the tank's internal walls, floor and joints, looking for cracks, flaking coatings and water staining. The team then marks any cracks and traces their length, since crack injection is measured per metre. Next, the surfaces are assessed to decide between options such as epoxy coating, which costs SAR 35–95 per m², or spray foam, at SAR 20–45 per m². Where the tank sits against the building or in a basement area, the inspector also checks adjoining surfaces, because basement waterproofing is priced at SAR 55–160 per m² and bathroom waterproofing at SAR 15–40 per m². The result is a written scope that lists each area and its measured size, so the owner can see exactly what is proposed before any work begins.

Before the visit, the owner should clear access to the tank lid, roof hatch or ground-level opening, and move stored items away from the tank walls. It helps to note when the leak was first seen, whether it worsens after rain, and which rooms or walls show damp. Photos of any staining or cracks are useful for the inspector. Keep the water supply lines and any pump switches accessible, and let the team know if the tank is currently in use, since that affects when it can be drained. Having these details ready lets the inspection move quickly and gives the owner a clear basis for comparing the proposed options.

If water is flowing, close the main valve first, then call or message with photos.
