Underground tank leak checks in Al Askan, Riyadh, start with the location itself. The centre of Al Askan sits at 24.5738, 46.8478, about 23.4 km from the centre of Riyadh, with an approximate radius of 1.2 km. The area lies around 571 m above sea level, which matters because elevation affects how water and pressure behave in buried pipework. The nearest wadi channel is about 0.8 km from the centre of Al Askan, so the technician will pay attention to drainage paths and how surface water could reach or undermine a buried tank during heavy rain. These are the first points checked, because they shape which signs of leakage are most likely to appear.

The rest is left to the site visit. The technician needs to see the actual tank, its age, its access points, and the condition of the ground around it. Whether the inner surface needs recoating is judged on the spot. Where coating is needed, the cost sits within SAR 25–70 per m², but the exact figure depends on the surface measured and the work required, so no estimate is given until the tank has been inspected. Pipe runs, valves, and any signs of staining or wet soil near the tank are also assessed in person rather than assumed from a description.

To help the technician arrive prepared, residents should note when they first noticed any change in water levels or smell, whether the building's supply has shown unexplained drops, and where the tank and access covers are located. Provide the building's layout, a record of any previous repairs, and details of any recent flooding or heavy rain near the property. Keep the access route clear and let the technician know if the tank area is shared with neighbouring buildings. Clear information at the start shortens the visit and makes the findings easier to explain to everyone who relies on the tank.

In apartment buildings, the floor below is often where a leak shows first.

Signs worth paying attention to

If you notice one of these signs in Al Askan, it is a good moment to talk to the team:

• The pump runs for longer periods
• A noticeable drop in the water level overnight
• Damp or salt marks on the tiles above the tank
• The tank needs refilling faster than usual

The most common causes

• A float valve that does not close, so water is wasted — we check this before anything else.
• Cracks in the concrete tank walls or floor.
• Construction joints and corners.

Tools we use in Al Askan

How the work is done, step by step

1. Safety first: Tank lids and confined spaces are handled with ventilation and a second person on site.
2. Documented level test: Filling and use are stopped and the level is recorded against time.
3. Isolating the tank from the network: This tells us whether the loss is from the tank body or from the supply line.
4. Checking the body and connections: Inlet, outlet and overflow connections are inspected.
5. Recommendation: You get the next step in writing: repair, waterproofing or a line test.
