Buried line leaks for apartments in Dammam

Before we start: what we know about Dammam

Team note on Dammam: 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.. Dammam is about 4.3 km from the sea coast (OpenStreetMap).

The centre of Dammam sits about 12 m above sea level (SRTM open elevation data).

Buried line leaks in apartment blocks in Dammam often start with a simple question: where does the water go once it leaves the main supply? Dammam's centre sits about 12 m above sea level, according to SRTM open elevation data, and the city is about 4.3 km from the sea coast, per OpenStreetMap. Our technicians therefore check the pressure and flow pattern at the building's entry point first, because a low-lying basement pipe and a rooftop tank connection behave very differently on this kind of gentle, coastal terrain. Before any excavation is discussed, the first step is to confirm whether the leak is on the supply side or the drainage side, since these lines are laid and repaired in different ways.

Several things are left to the site visit, because they cannot be judged from a distance. The technician will walk the route of the buried line, listen for the sound of escaping water, and check for damp soil, sunken paving or greener patches on the ground above the pipe. They will also inspect the water tank, look at its internal condition, and decide whether the leak is coming from the pipe or from a tank that has worn down over time. Tank internal coating is priced at SAR 25–60 per m², but the actual area and condition can only be measured on the spot, so no firm figure is given before the inspection.

To help the technician arrive prepared, please share the building's age, the number of apartments served, and any previous repair records you have. Note where you first noticed water, whether the water pressure has dropped in particular flats, and whether the problem is worse at certain times of day. Photos of damp walls, stains on ceilings, or the location of the water meter and tank are useful too. Keep access open to the roof, the basement and the meter room, and let the building management know in advance. This information makes the first visit faster and the findings clearer for everyone in the building.

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

Signs worth paying attention to

These are the signs most often linked to buried line leaks:

• The meter turns while everything inside the house is sound
• Sinking interlock paving
• A permanently green or muddy patch in the yard

Causes we see in the field

• A common cause: a joint under the interlock paving.
• The supply line from the meter to the tank — we check this before anything else.
• A broken irrigation line.

Tools and methods, and when we use them

The steps in order

1. Isolating the line: The buried section is separated from the house network.
2. Pressure test: The line is checked for pressure loss.
3. Tracer gas: A safe hydrogen–nitrogen mix escapes at the leak and is detected at the surface.
4. Recommendation: The proposed excavation point and its size.
