Signs that call for underground tank leak detection
These are the signs most often linked to underground tank leak detection:
- 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
Where the problem usually comes from
- A common cause: construction joints and corners.
- A common cause: cracks in the concrete tank walls or floor.
- A common cause: a float valve that does not close, so water is wasted.
Tools and methods, and when we use them
| Tool | What it finds | When we use it in Duba |
|---|---|---|
| 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 |
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.

Short answers for Duba
What is the first step of underground tank leak detection for schools?
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 Duba?
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.
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
The written output: the written level-test result and the recommended next step. The report is numbered and can be checked with its verification code.
Planning the visit in Duba
- 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).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- 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.
