Wondering whether the tank under your restaurant in Al Sly could be leaking without any warning sign? It is a fair question, and the facts give a clear starting point. Al Sly is centred at 24.6599, 46.8349, about 17.2 km from the centre of Riyadh, with an approximate radius of 1.2 km. The centre of the district sits about 606 m above sea level, according to SRTM open elevation data. Knowing where your site sits within this area helps us plan the visit around local access and conditions, so the inspection can be scheduled with your location in mind.

Our inspection for an underground tank in Al Sly follows a set order. First, the technician reviews the tank's location and records its position against the district coordinates above. Next, the tank is checked for leak signs and its condition is assessed, including the internal coating. Where coating work is needed, the cost is quoted per square metre, and the internal coating is priced at SAR 25–70 per m². The final step is a written summary of what was found and what action, if any, is recommended, so you can decide the next steps with clear information in hand.

Before the visit, gather a few details that will speed up the work. Note the approximate size and age of the underground tank, and any records of past repairs or coating work. Tell us which access point the technician should use behind the restaurant and whether any kitchen or dining hours should be avoided. If you already suspect a problem, such as a drop in stock levels or an unusual smell, write down when you first noticed it. Having these details ready means the technician can focus on the tank itself, and you will have a clearer picture of the situation from the start.

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

Signs that call for underground tank leak detection

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
• The tank needs refilling faster than usual

Where the problem usually comes from

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

How we choose the tool in Al Sly

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.
