What is specific about Al Askan for hidden water leak detection

The centre of Al Askan is at 24.5738, 46.8478, about 23.4 km from the centre of Riyadh, with an approximate radius of 1.2 km. The approximate area shown on the map is centred here. Main roads in or near Al Askan: Al Samh bin Malik Road.

The centre of Al Askan sits about 571 m above sea level (SRTM open elevation data). The nearest wadi channel is about 0.8 km from the centre of Al Askan (OpenStreetMap).

Al Askan sits at 24.5738, 46.8478, roughly 23.4 km from the centre of Riyadh, and its built-up core covers an approximate radius of 1.2 km. That compact footprint means many offices and commercial complexes here share older utility runs, so a leak in one building can be hard to separate from its neighbours. Our survey starts by mapping the site's supply and drainage routes before any listening equipment is set up, so that readings are attributed to the correct building and line.

The centre of Al Askan sits about 571 m above sea level, according to SRTM open elevation data. At that elevation, rooftop and ground-level storage tanks rely on steady pressure from pumps, and small pressure swings can push water into hidden joints and slab cracks. We therefore check pump cycling and pressure readings alongside acoustic tests, since a leak that appears only at certain pressures can be missed during a short visit. The nearest wadi channel lies about 0.8 km from the centre, according to OpenStreetMap. Seasonal runoff in such channels can saturate the ground around shallow pipework, which is why we note soil moisture near low-lying basements and car parks, and recommend rechecks after heavy rain.

Owners in this area often make the same errors, and our process is designed to avoid them. They tend to treat a damp patch as the leak itself, when the water may have travelled along a slab before surfacing. They also delay checking storage tanks until staining appears, when the wetted area has already grown. Another common mistake is repairing a single joint without testing the rest of the run, which leaves the next failure unseen. Where a tank needs protection, the internal coating typically falls in the range of SAR 25–70 per m², and we explain the figure in your site report so the cost is clear before any work begins.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.

When do you need hidden water leak detection?

The following signs are worth checking before they grow:

• A hissing or trickling sound in the wall after the taps are off
• A damp patch that slowly grows on a wall or ceiling
• A water bill higher than usual with no change in use

The most common causes

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

How we choose the tool in Al Askan

From the first visit to the report

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.
