Wondering whether the underground fuel or water tank behind your restaurant in Dyrab could be leaking? It is a fair question for any property owner here, and the answer starts with the location. Dyrab's centre sits at 24.4995, 46.6255, about 24.3 km from the centre of Riyadh, with an approximate radius of 1.2 km. The area sits about 744 m above sea level, and the nearest wadi channel runs roughly 0.9 km from the centre. Those conditions matter because groundwater movement and seasonal runoff can affect how soil around a buried tank behaves over time.

The inspection follows a clear sequence. A technician first reviews the tank's age, its material and the history of stock or water readings you have recorded. Next comes a check of the lines and fittings that connect the tank to the kitchen or the dispensing point, since leaks often start there. The tank itself is then examined, including its internal surface. Where coating wear is suspected, the work is priced by area, typically SAR 25–70 per m², so the technician measures the tank accurately before quoting. The visit closes with a written summary of findings and the steps recommended, so you can decide what to do next without guesswork.

Before the visit, gather your records of deliveries and usage for the past several months, the original installation or last service paperwork if you have it, and the access route to the tank and its manhole. Clear the area around the access point so the technician can work safely, and let your kitchen staff know when the visit is planned so routine operations can be paused. If you have noticed unusual readings, a damp patch near the tank, or a smell of fuel in the ground, note the dates and describe what you saw. These details help the inspection focus on the right places from the start.

For restaurants, visits are planned outside service hours and recorded for the premises file.

When do you need underground tank leak detection?

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

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

Where the problem usually comes from

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

How we choose the tool in Dyrab

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.
