Is there a leak in the underground water tank of my duplex in Syah, and how would anyone know without digging up the yard? Syah sits at about 24.6073 north, 46.7022 east, roughly 12.1 km from the centre of Riyadh, with an approximate radius of 1.2 km. The area stands about 579 m above sea level, and the nearest wadi channel runs about 0.4 km from the centre. Those conditions matter for underground tanks, because ground around the tank and the drainage paths nearby shape how water and soil move over time. A leak test is therefore a practical way to find out whether the tank is losing water before the problem shows up as damp walls or a drop in supply.

Our inspection for duplexes in Syah follows a clear sequence. First, we check the tank's condition and the pipework that connects it to the building, noting any visible wear or signs of seepage around the access points. Next, we run the leak detection test on the tank itself, recording the readings so you can see exactly what was measured. Where the tank lining shows deterioration, we explain the options for internal coating, which is priced at SAR 25–70 per m², with the final figure depending on the surface area that needs treatment. We then give you a written summary of findings and the recommended next steps, so the decision stays with you.

Before the visit, gather a few details that will speed up the work. Know the approximate size of the tank if you have it, and locate any original plans or previous maintenance records from the building. Note when you first noticed any change in water pressure, unusual wet patches in the yard, or a rise in the water bill. Clear a route to the tank access cover and make sure the surrounding area is reachable. Having this information ready helps us focus on the right parts of the tank and gives you a clearer picture of the condition in your duplex in Syah, Riyadh.

In a duplex, the two floors often share lines, so tests are done floor by floor.

Signs worth paying attention to

If you notice one of these signs in Syah, 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

Causes we see in the field

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

Tools and methods, and when we use them

From the first visit to the report

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.
