What is specific about Khobar for roof tank leak detection

Khobar is about 1.8 km from the sea coast (OpenStreetMap). The centre of Khobar sits about 9 m above sea level (SRTM open elevation data).

Team note on Khobar: 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..

Roof tank leak detection for offices and commercial complexes in Khobar starts with the location itself. The centre of Khobar sits about 9 m above sea level, and the city is roughly 1.8 km from the sea coast. Because the ground is low and close to the water, a technician will look first at how water is drawn into the building and at whether the tank's overflow and drain pipes are clear, since a slow leak here can easily reach the lower floors before it is noticed. The coastal setting also means salt-laden air can speed up corrosion on metal tank walls, seams, and fittings, so the first checks focus on visible rust, staining, and any damp patches on the walls below the tank.

Several points cannot be settled from a description alone and are left to the site visit. The technician will need to see the tank itself, climb to the roof safely, and check the inside surfaces for cracks, lifting, or bare patches. Where the internal lining is worn, the cost of renewing the coating is usually quoted per square metre, in the range of SAR 25–60 per m², so the size of the affected area determines the estimate. The exact source of a leak, whether it is a seam, a valve, a float, or a connection, can only be confirmed by inspection, and the technician will decide the order of repair once the tank has been emptied and dried enough to see clearly.

To help the technician arrive prepared, it is useful to note when the leak was first seen, whether the water level in the tank drops overnight, and where damp marks appear in the building below. Please also record whether the tank has had a previous coating repair, the type of water it holds, and any recent work on the roof. Clear access to the tank, the roof hatch, and the building's plant room will save time on the day. Sharing photos of stains or wet ceilings beforehand also gives the technician a starting point before arriving on site.

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

Signs worth paying attention to

The following signs are worth checking before they grow:

• A stain on the top-floor ceiling
• Water on the roof around the tank base
• Repeated spills from the overflow outlet

Where the problem usually comes from

• A common cause: inlet and outlet connections.
• A fibreglass or polyethylene tank cracking in the sun.
• A worn float valve — we check this before anything else.

How we choose the tool in Khobar

From the first visit to the report

1. Inspecting the base and connections: We look at where water gathers and trace it back.
2. Level test: The level is recorded with filling stopped.
3. Float and overflow check: We confirm whether water is escaping through the overflow rather than the tank body.
4. Recommendation: Repair of the connection, the float or the tank, stated in writing.
