How do you know if the underground water or fuel tank beneath your duplex in Tyba is leaking? For many owners the first sign is a drop in levels that nobody can explain, or damp patches appearing near the garden or the building's foundations. Tyba sits at about 24.5417 N, 46.8306 E, roughly 24.7 km from the centre of Riyadh, and its built-up area has a radius of approximately 1.2 km. The district lies at about 553 m above sea level, and the nearest wadi channel runs roughly 2.9 km from its centre. Our leak detection service is designed for duplexes in this setting, where tanks are often shared between two households and a small loss can go unnoticed for weeks.

The inspection follows a set order. A technician first reviews the tank's age, its material and the pattern of water or fuel use over recent months. The tank is then tested for pressure and volume change, and the inlet, outlet and connecting pipes are checked for seepage. Where the tank wall is suspected to be weak, the inner surface is examined, and if coating is needed the cost is in the range of SAR 25–70 per m², depending on the area treated. The technician records each reading and explains the findings to the owner before any repair work is proposed, so you can decide what happens next.

Before the visit, gather a few simple records that help the technician work faster. Note the dates when you first noticed low levels or wet ground, and keep recent meter readings or fuel delivery receipts. Let the other household in the duplex know the appointment time, since the tank may need to be isolated for part of the test. Clear access to the tank cover and the pump room, and make sure the area is free of parked cars and stored items. With these details ready, the inspection can focus on finding the source of the loss rather than searching for it.

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

Signs worth paying attention to

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

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

Where the problem usually comes from

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

How we choose the tool in Tyba

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.
