Wondering whether an underground tank on your Al Sla property could be leaking without any obvious sign? It is a fair question, and the answer starts with location. Al Sla is centred at 24.6540, 46.8543, about 19.3 km from the centre of Riyadh, with an approximate radius of 1.2 km. The district sits about 585 m above sea level, according to SRTM open elevation data. Because the area is compact and well defined, a single site visit can be planned around the tank's exact position within it, rather than relying on general assumptions about the neighbourhood.

Once the visit is booked, the inspection follows a set sequence. The technician first reviews the tank's history, its age, and any past repairs or changes to the fuel lines. Next comes a check of the surrounding area and the fill, vent and dispensing points, looking for staining, odours or signs of soil movement. Where the tank's internal condition is in question, the inspector assesses whether the inside surfaces need protection. Internal coating is priced at SAR 25–65 per m², so the inspection report will note the surface area involved, which helps you compare options before any work is approved. Each finding is recorded so you can see exactly what was tested and what was observed.

Preparing before the visit makes the inspection faster and more useful. Gather any records you have, including installation dates, previous inspection reports, fuel delivery logs and invoices for repairs. Note any changes you have seen, such as unexplained drops in fuel levels, wet patches near the tank, or unusual smells. Make sure the technician can reach the tank area, the access covers and the nearby pipework, and tell the site staff or tenants in advance so that nobody is surprised. Having the exact location of the tank on hand, referenced against the Al Sla coordinates if you have them, will also help the technician find it quickly.

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

Signs that call for underground tank leak detection

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

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

The most common causes

• A common cause: construction joints and corners.
• A common cause: cracks in the concrete tank walls or floor.
• A float valve that does not close, so water is wasted.

Tools and methods, and when we use them

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.
