Before we start: what we know about Dhahran

Team note on Dhahran: 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 Dhahran sits about 16 m above sea level (SRTM open elevation data).

Dhahran is about 5.9 km from the sea coast (OpenStreetMap).

Dhahran's centre sits about 16 m above sea level, and it lies roughly 5.9 km from the coast, so a school or warehouse here is not exposed to the same salt-laden air found right at the shoreline. Before quoting anything, the technician first checks the building envelope that matters most for heat and moisture: the roof, the external walls, and any ground-contact floor. Roof areas are the first priority because a flat roof on a commercial or school building takes the most direct sun. Liquid roof waterproofing is typically SAR 8–25 per m², and bitumen membrane is typically SAR 15–35 per m², so the choice between them depends on the condition of the existing surface and how much access the building can allow during term time.

The site visit settles what cannot be judged from a plan. The technician measures the real roof and wall areas, looks for cracks, and records where the old finish has lifted or blistered. Where cracks run through a structure, crack injection is priced at SAR 40–120 per metre and is usually sized only after the crack is opened up on site. Basement and ground-floor moisture is also assessed in person, since basement waterproofing ranges from SAR 50–150 per m² and the right method depends on whether water is coming through the walls or rising from below. Insulation boards such as XPS, at SAR 12–30 per m², are checked against the wall and roof build-up, along with any spray foam work at SAR 20–45 per m² and epoxy coatings at SAR 35–90 per m² in plant rooms or wash areas that need a hard-wearing finish. Any water storage tank in the building is inspected for internal coating needs, which run SAR 25–60 per m².

To help the technician arrive prepared, it is useful to have the building's drawings or a rough sketch with the roof, wall and floor areas marked, plus any previous repair records. Note which areas are used during the school day and which are empty at weekends, so work can be scheduled around occupancy. Keep a list of known problems such as leaks after rain, damp patches, or cracks that have grown, and say which rooms are affected. Clear access to the roof hatch, plant rooms and tanks saves time on the visit. With this information in hand, the technician can measure accurately, confirm which method suits the structure, and explain the options in plain terms.

For schools, the larger jobs are planned for weekends and holidays.

Signs that call for commercial & warehouse insulation

The following signs are worth checking before they grow:

• Leaks in a hangar or warehouse
• High heat that affects stored goods

The most common causes

• Old insulation — we check this before anything else.
• Blocked gutters — we check this before anything else.
• A common cause: metal-sheet joints.
