Wondering whether an underground fuel or water tank on your Al Fwta property could be leaking? Al Fwta is a locality in Riyadh, centred at 24.6417, 46.7105, about 8.8 km from the centre of Riyadh, with an approximate radius of 1.2 km. The centre sits roughly 588 m above sea level, so local ground conditions and drainage are worth considering when a tank is checked. The cost of any repair depends on the work needed; for internal tank coating, the rate is SAR 25–65 per m², so the size of the tank surface is the key figure to know before you call for a quote.

A leak detection visit for an underground tank in Al Fwta usually begins with a review of the tank's age, its records and any signs of trouble, such as unexplained drops in stock or damp soil near the fill points. The technician then checks the tank and its connecting pipework, looking at the fittings, vents and fill points for wear or seepage. Where the tank cannot be seen directly, the inspection relies on methods that test the tank's tightness and the surrounding ground. Each step is recorded so the owner receives a clear account of what was found and what, if anything, needs to be repaired or recoated. Nothing in this process should be rushed, and any findings should be explained in plain terms before work begins.

Before the visit, gather what will help the technician most. Have the tank's installation date, any previous repair or coating records, and a note of the contents stored in it. Record recent consumption or stock levels so that any unusual loss can be compared against normal use. Clear access to the fill points, vents and the area above the tank will save time on the day. It also helps to note any damp patches, odours or changes in the ground around the site. With this information ready, the visit can focus on the tank itself, and you will have a clearer basis for deciding whether repair or internal coating is the right next step.

Signs worth paying attention to

These are the signs most often linked to underground tank leak detection:

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

How we choose the tool in Al Fwta

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.
