Why water tank waterproofing differs in Tabuk

Team note on Tabuk: 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 Tabuk sits about 762 m above sea level (SRTM open elevation data).

Can a water tank be waterproofed in Tabuk without emptying the whole building or breaking open the walls? Property owners here ask this often, and the answer depends on what the tank is made of and where the leak sits. The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data), a high, dry setting where roof tanks and ground tanks are exposed to strong sun and wide temperature swings, which is why cracks and failed seals show up over time. For tank work, the relevant options on our price list include tank internal coating at SAR 25–55 per m², crack injection at SAR 40–115 per metre, and epoxy coating at SAR 35–85 per m². Because the cost and method differ, the first step is always to identify the problem before choosing a treatment.

The inspection starts with a visual check of the tank's inner and outer surfaces, the inlet and outlet fittings, and the joints where the tank meets its base or support. The technician looks for hairline cracks, flaking old coating, damp patches, and any stains that suggest slow seepage. Where a crack is found, its length is measured in metres so the work can be priced per metre. Surfaces are then tested for dampness and cleanliness, since coatings will not bond to dust, algae or loose material. The result of the inspection is a short written note describing the affected areas and the recommended method, so the owner can compare options before any work starts. No section of the tank is opened up unless the inspection shows that it is needed.

Before the visit, it helps to prepare a few things. Note when the leak was first noticed and whether it appears after the tank is filled or during use, since this points to different causes. Have a rough idea of the tank's size and material, and whether it sits on the roof, at ground level or below ground. Arrange access to the tank and its valves, and tell the technician if the water supply must be kept running for the household. If there are old repairs or previous coatings, mention them, because old layers may need removing before new ones are applied. Clear the area around the tank so the inspection can be carried out safely and without delay.

The aim is to locate the cause with instruments first, so any opening is limited to one point.
