Why underground tank leak detection differs in Jubail

Team note on Jubail: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Jubail sits about 4 m above sea level (SRTM open elevation data).

Jubail is about 0.9 km from the sea coast (OpenStreetMap).

Is there a way to know whether the underground fuel or water tank beneath your hotel or serviced apartment building is leaking before the problem reaches the soil and the bill? In Jubail, where the centre sits about 4 m above sea level and the coast is only about 0.9 km away, that question matters more than many owners expect. Low-lying ground close to the sea can mean groundwater sits near the tank, so a leak is harder to contain and easier to spread. Our service is designed to answer the question early, while the problem is still small and manageable.

The inspection begins with a review of the tank's age, its material, the pipework connected to it, and any records of past readings or repairs. The technician then carries out a leak test on the tank and its lines, checks the fill and vent points, and looks for signs of moisture or staining around the access covers. Where a tank has an internal coating, its condition is assessed as part of the check. If a coating repair is needed, the cost is quoted per square metre, typically in the range of SAR 25–60 per m², depending on the surface and the work involved. You receive a written summary of what was tested, what was found, and what options are available, so you can decide on the next step without pressure.

Preparing for the visit makes the inspection faster and more accurate. Please have the tank's installation date and any previous inspection reports ready, along with the consumption records for the past several months, since a sudden change in usage can point to a leak. Clear the access to the tank covers and the surrounding area so the technician can reach the fill and vent points safely. Let the staff who handle the building's fuel or water supply know the visit is coming, and note any unusual smells, wet patches, or drops in tank level you have noticed. With this information in hand, the visit can focus on finding the answer rather than gathering it.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

When do you need underground tank leak detection?

If you notice one of these signs in Jubail, 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
• Damp or salt marks on the tiles above the tank

Causes we see in the field

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

Tools we use in Jubail

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.
