Why hidden water leak detection differs in Al Mnar

The centre of Al Mnar is at 21.6024, 39.2375, about 9.4 km from the centre of Jeddah, with an approximate radius of 1.2 km. The service-area circle on the map below is drawn from this point. Al Mnar is about 11.3 km from the sea coast (OpenStreetMap).

The centre of Al Mnar sits about 45 m above sea level (SRTM open elevation data). Main roads in or near Al Mnar: Hadi Al-Sham Road.

Al Mnar sits at about 21.6024, 39.2375, roughly 9.4 km from the centre of Jeddah, and its built-up core spans an approximate radius of 1.2 km. That compact footprint matters for leak work. Our technicians can plan a full apartment block survey from a single base point rather than travelling across a sprawling district, which keeps appointments focused and makes follow-up visits easier to coordinate with building management.

The centre of Al Mnar lies about 45 m above sea level, according to SRTM open elevation data, and the area is about 11.3 km from the sea coast. Elevation affects how water is supplied and stored, so many buildings rely on rooftop or ground-level tanks and pumping. Pressure changes between floors can push water into concealed joints and behind wall finishes, which is why we inspect tank connections and risers as part of any hidden leak check. Being roughly 11.3 km inland also means the coastal humidity that accelerates corrosion is less intense here, yet damp patches still develop around pipework, so moisture readings are taken at the same time as acoustic testing.

Owners in Al Mnar often wait until a stain or a rising water bill makes the problem obvious, by which point water has already soaked into slabs or plaster. Another common mistake is treating a leaking tank as a simple repair without considering its lining; internal coating for tanks is priced at SAR 25–65 per m², and a failing coating can cause leaks that patching alone will not fix. Owners also tend to call a plumber for one visible drip and overlook the rest of the system, or they close a wall opening without a moisture check first. We recommend a full survey before any work begins, so the repair addresses the actual source rather than the first place water appeared.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.

Signs that call for hidden water leak detection

These are the signs most often linked to hidden water leak detection:

• The meter keeps turning with every tap closed
• A water bill higher than usual with no change in use
• A damp patch that slowly grows on a wall or ceiling

Causes we see in the field

• A corroded joint inside a wall — we check this before anything else.
• A cracked pipe under floor tiles — we check this before anything else.
• A hot line that expands and contracts with use — we check this before anything else.

Tools we use in Al Mnar

The steps in order

1. Meter test: We stop all use and watch the meter to confirm whether water is actually being lost.
2. Line isolation: We close valves one line at a time to see which line loses pressure.
3. Acoustic listening: We follow the sound of water escaping under pressure and compare its strength between points.
4. Thermal imaging and moisture mapping: We map how far the wet area spreads behind paint and tiles.
5. Documentation: Readings, photos and the likely position go into a written report.

What we advise against

• Repainting the stain while the moisture keeps coming back
• Breaking tiles at random before the line is identified

What you receive

The written output: a technical report with the readings, the likely leak position and a confidence level. The report is numbered and can be checked with its verification code.
