Underground tank leak detection in Madinah: for companies (annual contract)
In short: In Madinah (Madinah), underground tank leak detection (for companies (annual contract)) begins with the documented tank level test and the pressure test and line isolation; nothing is opened until the position is clear. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Pricing starts from Inspection visit (SAR 150 per visit), and other items are quoted after the visit.
Before we start: what we know about Madinah

Underground tank leak detection in Madinah starts with the ground itself. The centre of Madinah sits about 589 m above sea level, according to SRTM open elevation data, and that figure is the first thing worth noting for a company planning an annual check. Elevation matters for how fuel and water move through the site, how groundwater may collect around a buried tank, and how the local drainage behaves after rain. A technician arriving for the annual inspection will therefore look at the tank's surroundings and the site's slope before opening anything, because a leak that is hard to see in the tank can still show up as wet soil or unusual readings around the fill points and pipework.
Several things are deliberately left to the site visit. The actual condition of the tank walls, the seals on the fill and vent lines, and the tightness of the piping can only be judged on location with the right equipment and the tank's own records. Whether the internal lining needs attention is also a matter for inspection rather than assumption. For budgeting, the tank internal coating is quoted at SAR 25–60 per m², but the true area depends on the tank's dimensions and condition, so the technician will measure first and confirm the scope on the day. Anything that cannot be confirmed from a distance is held back until the tank has been seen in person.
To help the technician work efficiently, have the tank's installation date, capacity, and product history ready, along with any previous inspection reports and records of repairs or fuel-level discrepancies. Note any unexplained drops in stock, damp patches, or odours noticed since the last check, and make sure the access route to the fill points and monitoring wells is clear. Let the site contact know the operating hours so that fuel deliveries and tank work do not overlap. With this information in hand, the visit can focus on testing and confirming the tank's condition rather than gathering background details, and the company receives a clearer picture of what the annual check has found.
For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
Signs worth paying attention to
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
- The pump runs for longer periods
Where the problem usually comes from
- A common cause: construction joints and corners.
- Cracks in the concrete tank walls or floor — we check this before anything else.
- A float valve that does not close, so water is wasted — we check this before anything else.
Tools we use in Madinah
| Tool | What it finds | When we use it in Madinah |
|---|---|---|
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
| Ground microphone and contact listening | The sound of water escaping under pressure in walls and floors | Limits: weaker with background noise and deep lines |
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
| Pressure test and line isolation | Which line (hot/cold, floor by floor) loses pressure | Limits: needs working valves to isolate lines |
How the work is done, step by step
- Safety first: Tank lids and confined spaces are handled with ventilation and a second person on site.
- Documented level test: Filling and use are stopped and the level is recorded against time.
- Isolating the tank from the network: This tells us whether the loss is from the tank body or from the supply line.
- Checking the body and connections: Inlet, outlet and overflow connections are inspected.
- Recommendation: You get the next step in writing: repair, waterproofing or a line test.

Questions from Madinah
What is the difference between standard spraying and integrated pest management?
Standard spraying treats visible symptoms only, while integrated pest management includes diagnosis, sealing entry points, and multiple methods for longer-lasting results.
Could the leak be caused by weak waterproofing rather than the pipes?
Yes, damage to the waterproofing layer beneath the bathroom floor is one of the most common causes of leaks, especially in older buildings. In this case, water seeps through the tile joints into the screed and then down to the ceiling below. A specialized inspection can distinguish this from a pipe leak.
What is the difference between drain unblocking and drain cleaning?
Unblocking removes an existing blockage that prevents drainage, while cleaning is a preventive procedure that removes deposits and grease from pipes before they cause a blockage.
What is the first step of underground tank leak detection (for companies (annual contract))?
We start with safety first (tank lids and confined spaces are handled with ventilation and a second person on site), then documented level test (filling and use are stopped and the level is recorded against time).
How much does underground tank leak detection cost in Madinah?
From our published price list: Inspection visit SAR 150 per visit; Tank internal coating (per m²) SAR 25–60 per m². Quantities are confirmed at the inspection.
What do I get at the end?
The written level-test result and the recommended next step, in a technical report that carries a verification code.
What we advise against
- Waterproofing the tank before confirming the loss is from the tank and not the line
- Ignoring the float valve
The written outputs
You receive: the written level-test result and the recommended next step, in a technical report with a verification code.
If you live in Madinah and are new to the area
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
