Hidden water leak detection for restaurants in Jeddah

Why hidden water leak detection differs in Jeddah

Team note on Jeddah: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data).

Jeddah is about 2 km from the sea coast (OpenStreetMap).

A restaurant owner in Jeddah often notices a problem only after it has been running for some time. The kitchen floor feels damp near the grease trap, a cabinet under the sink smells faintly sour, or the water bill climbs without any obvious reason. Hidden leaks behind walls, under tiles and beneath the cold room are easy to miss during a busy service, and by the time staining or soft flooring appears, the damage may already reach beyond the kitchen into the dining area.

The local setting matters here. The centre of Jeddah sits about 15 m above sea level, and the city lies about 2 km from the sea coast. That means the ground is low-lying and close to the coastline, so moisture from the surrounding area can linger in floors and walls, making a small leak harder to tell apart from ordinary dampness. For a restaurant, this makes regular checks more important than relying on sight alone. Water that seeps under tiles near a sea-facing building can spread quietly, so an owner should not assume that a dry-looking surface means a dry structure beneath.

Start by mapping every place water enters or leaves the premises: the main supply line, the water heater, dishwashing points, ice machines, the cold room and any storage tanks. Next, check the meter when the kitchen and washrooms are closed. If the reading still moves, a leak is likely, and you can narrow the source by shutting off branches one at a time. Then inspect exposed pipework and joints for wet patches, and listen for hissing near walls and floors. If you keep a water storage tank on site, note that internal coating work is priced at SAR 25–65 per m², so compare the tank surface area against that range before deciding on repairs or recoating. Finally, record each finding with the date, so you can see whether the problem is growing and share a clear picture with whoever carries out the repair.

For restaurants, visits are planned outside service hours and recorded for the premises file.

Signs that call for hidden water leak detection

If you notice one of these signs in Jeddah, it is a good moment to talk to the team:

• 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

Where the problem usually comes from

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

Tools we use in Jeddah

How the work is done, step by step

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.

Common mistakes we see

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

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.
