Consider a homeowner in Alkharj whose property has an underground fuel or water tank buried beside the driveway or garden. Nothing looks wrong at first. The lawn is green, the pump works, and the monthly bills seem normal. Then a damp patch appears near the boundary wall, or the level in the tank drops faster than usual. Many owners only start asking questions at this stage, when the problem has already spread into the soil. Tanks buried for years are easy to forget, and a small leak can go unnoticed for a long time.
The local facts matter here. The centre of Alkharj sits about 439 m above sea level, which places the city on a broad inland plateau rather than a low coastal plain. Ground conditions and drainage on such a site can shift with seasonal rain and irrigation, so a patch of moisture that appears after watering may not be a sign of a leak on its own. An owner should therefore compare readings over time rather than relying on a single observation. Repairs also carry a cost that depends on the tank itself. Internal coating is priced at SAR 25–60 per m², so the surface area of the tank is a key figure when comparing quotes for re-coating versus replacement. Asking for the measured area in writing helps keep estimates honest.
Start by recording the current level of the tank and the date, then repeat the reading at the same time each week for several weeks. Note any unexplained drops, wet ground, or unusual smells near the tank and the pipework. Next, check the fill and vent pipes and the dispensing lines for visible wear, and keep a record of any previous repairs or coating work. Ask a qualified inspector to test the tank and confirm the surface area before requesting any quote. Compare at least two written quotes against the stated coating rate per square metre. Finally, keep every report and invoice together so that the history of the tank is clear for future buyers, insurers, and maintenance crews.
Each job ends with a written report that carries a verification code you can check on our site.
Signs that call for underground tank leak detection
If you notice one of these signs in Alkharj, it is a good moment to talk to the team:
- The pump runs for longer periods
- A noticeable drop in the water level overnight
- 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.
- Cracks in the concrete tank walls or floor.
- Construction joints and corners.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| 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 |
| 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 |
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.

Common questions about underground tank leak detection in Alkharj
Does an underground tank require waterproofing even if it is new?
Yes, concrete is naturally porous, which can lead to leaks or groundwater seepage. Applying epoxy or cementitious insulation from the start maintains water quality and protects the structure from corrosion.
Do you need to evacuate the building during renovation work?
It depends on the type and scope of the work. Surface work such as plastering and painting usually does not require evacuation, while partial or full evacuation may be advised in cases of structural reinforcement, and the contractor determines this after inspection.
What is the first step of underground tank leak detection (with a verifiable technical report)?
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 Alkharj?
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
- Ignoring the float valve
- Waterproofing the tank before confirming the loss is from the tank and not the line
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.
