What is specific about Baqiq for bitumen membrane

The centre of Baqiq sits about 83 m above sea level (SRTM open elevation data). Main roads in or near Baqiq: King Fahd Road.

Team note on Baqiq: 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..

Baqiq is a town about 83 metres above sea level, which is the first fact a bitumen membrane crew should note before anything else. Bitumen membrane for a company's roof, podium or plant-room slab is priced at SAR 15–35 per m², and that range is the starting point for an annual contract covering several sites. Because the elevation sits well above the coast, the first checks at each company premises focus on the substrate: whether the existing surface is sound, dry enough to take primer, and free of loose material that would stop the membrane bonding. Those checks come first because a membrane laid over a weak base will fail regardless of how carefully the sheets are lapped.

Other items are left to the site visit, since they depend on conditions that cannot be known from the desk. The technician will look at the actual condition of the roof, including ponding areas, outlets, upstands and any cracks that might need separate treatment. Where a crack needs injecting, that work is priced separately at SAR 40–120 per metre, and the decision about whether it is needed belongs to the inspection. The same applies to whether a roof area is better served by liquid roof waterproofing at SAR 8–25 per m² or by XPS boards at SAR 12–30 per m² as part of a wider scheme. The choice of system follows what is found on the roof, not a fixed rule across the contract.

The information below helps the technician plan the job before arrival. Note the total roof area in square metres, the number of separate roof levels, and any plant, tanks or rooftop equipment that must be lifted or protected during the work. Record how the roof is currently used, whether it is accessible for foot traffic, and when the company can allow work to take place without disrupting operations. Mention any previous waterproofing and when it was laid, as well as any known leaks inside the building below. Sharing these details in advance lets the crew bring the right materials and schedule the visit once, which keeps the annual contract running smoothly for everyone involved.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
