Is there a way to tell whether an underground tank on a property in Al Shafa, Riyadh, is leaking without digging it up? For many owners the first sign is a drop in stock or an unexplained change in ground conditions, and they want to know what can be checked before any work begins. Al Shafa is largely commercial, with shops and offices, so a leaking tank can affect daily trading and neighbouring premises, which makes an early and orderly check worth the effort. The centre of Al Shafa sits at 24.7969, 46.6401, about 9.9 km from the centre of Riyadh, with an approximate radius of 3 km, and the area sits about 656 m above sea level.
The inspection begins with a review of the tank's records, age, fuel or liquid history and any recent changes in usage, followed by a check of the surrounding ground and the pipework that connects the tank to the premises. Where a leak is suspected, the team carries out tightness testing and looks at inventory differences over time to narrow down the likely source. Because the nearest wadi channel is about 1.1 km from the centre of Al Shafa, the survey also considers how groundwater and surface water might move around the site. Where the tank interior has deteriorated, internal coating is one repair option, and the price range given for tank internal coating is SAR 25–65 per m², with the final figure depending on the surface area involved.
Before the visit, gather any delivery and dispensing logs, the installation or maintenance paperwork for the tank and pipework, and a note of any unusual smells, wet patches or changes in pump performance. Clear access to the tank cover, fill points and dispensers so the team can work without delay, and tell staff which areas of the premises are in regular use. If the property is part of a shared building or complex, let the other occupants know in advance that testing may take place. Having this information ready helps the inspection finish sooner and gives you a clearer picture of what, if anything, needs attention.
The aim is to locate the cause with instruments first, so any opening is limited to one point.
Signs worth paying attention to
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
- The pump runs for longer periods
Causes we see in the field
- A common cause: construction joints and corners.
- Cracks in the concrete tank walls or floor — we check this before anything else.
- A common cause: a float valve that does not close, so water is wasted.
How we choose the tool in Al Shafa
| Method | What it helps with | Its role in Al Shafa |
|---|---|---|
| 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.
