Underground tank leak detection for duplexes in Al Mrslat, Riyadh starts with the location itself. The centre of Al Mrslat sits at 24.7489, 46.6899, about 4.2 km from the centre of Riyadh, and the neighbourhood extends over an approximate radius of 1.2 km. Because the area is a compact residential district at that distance from the city centre, the first things we check are the tank's position relative to the duplex, the access route for the inspection equipment, and whether the tank sits within the same rough footprint as the building's other utilities. The ground here sits about 632 m above sea level, so we also note how the site drains after rain, since surface water can mask or mimic signs of a leak around a buried tank.
What is left to the site visit is the part that cannot be judged from a map. The technician will confirm the tank's actual condition, the state of the fittings and pipework, and whether the tank's internal lining has worn or cracked. If the lining needs repair or replacement, the cost is decided on site, since internal coating is quoted per square metre at SAR 25–70 per m², and the final figure depends on the measured surface area and the coating system chosen. Nothing about the price should be assumed before the inspection is complete. The technician will also decide whether a leak test is needed, and how thoroughly the surrounding soil and groundwater should be checked before any conclusion is drawn.
Information that helps the technician makes the visit faster and more accurate. Please have the tank's age, its approximate capacity, and the fuel or liquid it has held available, along with any past repair records. Note any recent drops in stock levels, unexplained odours near the tank, or damp patches in the yard or on the duplex walls. Tell us where the tank and fill points are, and whether the access cover can be opened on the day. Clear access to the tank area and to the duplex's utility room will save time. With these details in hand, the technician can plan the visit around the actual site rather than guessing from the street.
In a duplex, the two floors often share lines, so tests are done floor by floor.
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
- Construction joints and corners — we check this before anything else.
- 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
| Method | What it helps with | Its role in Al Mrslat |
|---|---|---|
| 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.
