Is there a leak in the underground tank at my property in Al Mshaal, and how do I find out without digging up the yard? Many owners here ask this when fuel or water levels seem to drop without explanation. Al Mshaal sits at roughly 24.6151, 46.8509, about 20.9 km from the centre of Riyadh, within an approximate radius of 1.2 km. The area lies about 596 m above sea level, and the nearest wadi channel is about 1.9 km from the centre, which matters because ground conditions and drainage can affect how a buried tank behaves over time. Leak detection starts with a clear picture of the tank itself, so the specialist will look at the tank's age, its material and any signs of past repair before deciding what testing is needed.

The inspection normally follows a set sequence. The technician first reviews your records of stock levels, meter readings and any unusual odours or wet patches around the fill point or the surrounding ground. Next comes a visual check of the accessible fittings, lines and the top of the tank. Testing then confirms whether the tank is losing product, and the results are explained to you in plain terms. If repair or recoating is needed, the cost depends on the work involved; for internal coating, the price range quoted for this service is SAR 25–65 per m², so the tank's surface area determines the final figure. You will receive a written summary of what was found and the options available, and you decide the next step.

Before the visit, gather a few things so the inspection is quick and accurate. Write down the tank's approximate capacity, its installation date if you know it, and any previous repairs or testing. Keep your recent delivery receipts and stock or meter readings for at least several weeks, since these show the pattern of any loss. Clear access to the fill point, vent and inspection cover, and tell the technician about any nearby pipes or structures you are aware of. Having the property deed or building details ready also helps the team confirm the location. With this information in hand, the visit can focus on finding the answer rather than gathering basic details.

Signs that call for underground tank leak detection

The following signs are worth checking before they grow:

• 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

Where the problem usually comes from

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

The steps in order

1. Safety first: Tank lids and confined spaces are handled with ventilation and a second person on site.
