Is my water tank in Al Aqyq, Riyadh, really in need of waterproofing, and how do I know before the leaks start? Many apartment owners here notice damp patches or a drop in water quality and wonder whether the tank itself is failing. The answer depends on the tank's condition, and a proper inspection is the only reliable way to find out. Al Aqyq's centre sits at 24.7740, 46.6309, about 8.1 km from the centre of Riyadh, with an approximate radius of 2.8 km, and its centre is about 647 m above sea level. The nearest wadi channel is about 0.7 km from the centre, so the surrounding ground can carry seasonal runoff that puts extra stress on tank walls and joints.

Our inspection starts with a visual check of the tank's internal and external surfaces, looking for hairline cracks, flaking coatings, and staining along the walls and floor. The technician then assesses where moisture is getting in and what kind of protection suits the tank, whether that is a tank internal coating, an epoxy coating, or crack injection along active cracks. Where the tank sits against or below other structures, the check also covers basement and bathroom areas that share the same moisture path. Each surface is measured, so the scope of work and the costs can be set out clearly before any job begins. The findings are explained in plain terms so you can decide what needs attention first.

Before the visit, clear access to the tank lid, the ladder or hatch, and any nearby plumbing so the technician can work without delay. Note when you have seen damp patches, discoloured water, or unusual noises from the tank, and keep any previous repair records or plans for the building. If the tank is empty during the visit, the inspection is easier and more thorough, so ask the building manager to arrange this in advance. Having this information ready helps the visit run smoothly and gives you a clear basis for choosing the right repair.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
