In short: Underground tank leak detection for offices & commercial complexes in Alwajh starts with the documented tank level test, then the pressure test and line isolation, before anything is opened. Alwajh is about 0.7 km from the sea coast (OpenStreetMap). Pricing starts from Inspection visit (SAR 150 per visit), and other items are quoted after the visit.

When do you need underground tank leak detection?
These are the signs most often linked to underground tank leak detection:
- Damp or salt marks on the tiles above the tank
- The tank needs refilling faster than usual
- The pump runs for longer periods
Where the problem usually comes from
- Cracks in the concrete tank walls or floor — we check this before anything else.
- Construction joints and corners — we check this before anything else.
- 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 Alwajh |
|---|---|---|
| Ground microphone and contact listening | The sound of water escaping under pressure in walls and floors | Limits: weaker with background noise and deep lines |
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
| Pressure test and line isolation | Which line (hot/cold, floor by floor) loses pressure | Limits: needs working valves to isolate lines |
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
The steps in order
- 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 Alwajh
Where does underground tank leak detection for offices & commercial complexes start in Alwajh?
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 Alwajh?
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.
What we advise against
- Ignoring the float valve
- Waterproofing the tank before confirming the loss is from the tank and not the line
The written outputs
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.
If you live in Alwajh and are new to the area
- 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.
- 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).
