How do I know if the underground fuel or water tank under my villa in Al Aard is leaking? Many owners here only notice a problem when the monthly bill rises or a damp patch appears near the garden wall, so it helps to check early. Al Aard is centred at 24.8935, 46.6060, about 21.2 km from the centre of Riyadh, with an approximate radius of 8 km. The centre sits about 671 m above sea level, and the nearest wadi channel is about 1 km from the centre. Because of this terrain and the seasonal flow of rainwater, tanks buried in these neighbourhoods can be exposed to moisture and ground movement, which is why a visual and pressure-based check is worth scheduling.

The inspection follows a clear sequence. A technician first reviews the tank's age, material and any past repairs, then checks the fill and vent lines and the area around the access cover for staining or soft ground. Next, the internal condition is assessed, and where coating wear is found, the work is estimated per square metre, with internal coating typically priced at SAR 25–70 per m². The tank is then tested for loss of volume or pressure so that a small leak can be confirmed rather than guessed at. Finally, the technician records the findings in writing and explains which repairs are urgent and which can wait, so you can plan the work without pressure.

Before the visit, gather a few simple details to speed things up. Note when you first noticed a change in consumption, any smell of fuel or unusual damp near the tank, and the date of the tank's installation if you have it. Clear the access area so the technician can reach the cover and fill points, and keep children and pets away from the excavation zone. If the property has had recent heavy rain or runoff from the wadi side, mention it, as it can affect the results. Having these notes ready means the inspection can focus on what matters and give you a clear picture of your villa's tank.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.

Signs that call for underground tank leak detection

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

• A noticeable drop in the water level overnight
• The pump runs for longer periods
• 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.
• Construction joints and corners.
• Cracks in the concrete tank walls or floor — we check this before anything else.

How we choose the tool in Al Aard

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.
