Why building & facility leak surveys 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).

Imagine the owner of a mid-sized office building in Jeddah who notices a damp patch spreading across a ceiling on the upper floor. A few weeks later, a staff member reports a musty smell near the lift lobby, and the water bill has crept up without any obvious reason. The owner wants to know where the water is going, whether the building is losing it through pipes, tanks or joints, and how much disruption a repair will cause to tenants. For a commercial property, a small leak that goes unnoticed can quickly turn into damaged finishes, lost rentable space and complaints from occupants.

These symptoms matter more in Jeddah than they might elsewhere. The centre of Jeddah sits about 15 m above sea level, and Jeddah is about 2 km from the sea coast. That combination means the city's buildings are close enough to the coastal air to be exposed to salt-laden moisture, while the ground and drainage conditions around them can vary block by block. Water that escapes from a pipe or tank can move through structure and finishes in ways that are not always visible from the surface. For an office owner, this means a leak survey is worth doing before a patch becomes a structural or hygiene problem, not after.

A practical approach starts with a clear scope. First, review the building's water supply and drainage layout, including the roof tanks, risers and any water features, so you know where leaks are most likely. Second, check the water meter readings over a set period and compare them with occupancy, since a rise without more people or activity points to a hidden loss. Third, inspect accessible areas such as plant rooms, shafts, ceilings and car park walls for staining, efflorescence or soft plaster. Fourth, where a storage tank is involved, budget for its internal coating condition, which is typically priced at SAR 25–65 per m², so the cost of restoration can be weighed against the cost of repeated repairs. Finally, prioritise repairs by risk, fixing active leaks near electrical equipment or occupied floors first, and keep a dated record of findings so tenants and management can see what was done.

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

Signs worth paying attention to

These are the signs most often linked to building & facility leak surveys:

• The building pump runs continuously
• A high shared water bill for a building
• Repeated damp in several apartments

Causes we see in the field

• A common cause: floor-level connections.
• A common cause: a shared tank.
• A shared riser line — we check this before anything else.

Tools and methods, and when we use them

From the first visit to the report

1. Network survey: Risers, tanks and floor branches are listed first.
2. Isolating floors: Floors are isolated one by one to locate the loss.
3. Listening on the risers: Acoustic checks along the vertical lines.
4. Facility report: Positions and priorities for the owner or facility manager.

Common mistakes we see

• Testing one apartment when the shared line is the source

What you receive

The written output: a facility report with the positions and priorities. The report is numbered and can be checked with its verification code.
