Underground tank leak detection in Madinah: before summer & rain season
In short: Underground tank leak detection (before summer & rain season) in Madinah starts with the documented tank level test, then the pressure test and line isolation, before anything is opened. 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.
What is specific about Madinah for underground tank leak detection
The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Team note on Madinah: 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..
Madinah sits at about 589 m above sea level, according to SRTM open elevation data, which places the city on a high inland plateau rather than near the coast. For underground tank owners, this matters because the ground above and around a buried tank is shaped by the same dry, heated conditions that define the region. Our leak detection visits start with a check of the tank's position relative to the surface, the condition of fill and vent pipes, and any signs of settling in the surrounding soil, since these are the points where stress tends to show first.
Tank internal coating (per m²): SAR 25–60 per m² is the figure we use when we explain repair options to owners. Coating condition is central to leak detection, because a degraded internal lining can allow water or fuel to reach the steel shell before any visible seepage appears. When we assess a tank, we note the coating's age, any blistering or flaking, and whether the cost of recoating is likely to be lower than the cost of repeated patching. The per-square-metre range helps owners compare quotes on a like-for-like basis, so the price is tied to the actual surface area of the tank rather than a flat fee.
Many owners make the same errors, and avoiding them saves money and disruption. The most common is waiting for a fuel shortfall to become obvious before arranging a check, when small leaks have often been running for some time. Another is treating a single dry-stick reading as proof that a tank is sound, when the reading may miss a slow leak in a corner of the tank. Owners also tend to skip records of past repairs and coating work, which makes it hard to judge whether a problem is new or recurring. We recommend scheduling a check before the hot season and again before the rainy months, when groundwater movement can change what a test shows.
Checks before summer and before the rain season catch problems while they are still small.
Signs worth paying attention to
If you notice one of these signs in Madinah, 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
Where the problem usually comes from
- A common cause: a float valve that does not close, so water is wasted.
- A common cause: construction joints and corners.
- Cracks in the concrete tank walls or floor.
Tools we use in Madinah
| Method | What it helps with | Its role in Madinah |
|---|---|---|
| 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 |
| 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 |
From the first visit to the report
- 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.
Where does underground tank leak detection (before summer & rain season) start in Madinah?
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).
What 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 receive after the work?
The written level-test result and the recommended next step, in a technical report that carries a verification code.
Common mistakes we see
- Waterproofing the tank before confirming the loss is from the tank and not the line
- Ignoring the float valve
What you get after the work
You receive: the written level-test result and the recommended next step, in a technical report with a verification code.
Practical notes for residents of Madinah
- You can message us on WhatsApp in English; the booking details are sent back to you in the chat to confirm before the visit.
- The Saudi weekend is Friday and Saturday; mention your preferred day and time when booking.
- 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).
