Bitumen membrane in Yanbu: the local context

The centre of Yanbu sits about 6 m above sea level (SRTM open elevation data). Yanbu is about 1.2 km from the sea coast (OpenStreetMap).

Team note on Yanbu: 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.. Main roads in or near Yanbu: King Abdulaziz Road, Umluj Road, Al Hanan Street.

Yanbu's centre sits about 6 m above sea level, and the town lies roughly 1.2 km from the coast, so a technician arriving at a rest house or farm here starts by reading the roof and the ground rather than assuming the same conditions as an inland site. The proximity to the sea means salt-laden air, which affects how quickly exposed bitumen and fixings weather, and the modest elevation means that rainwater drains off the roof surface rather than pooling in deep depressions. Before any quote is firm, the first checks are the roof's pitch and whether it is flat or sloped, the condition of the existing surface, and where water currently collects or runs off. These observations decide whether a bitumen membrane is the right system for the job, or whether a liquid roof waterproofing system, which is priced at SAR 8–25 per m², might suit a roof with complicated edges better.

Several things can only be settled on the site visit. The technician needs to measure the true roof area and confirm the exact length of any parapets, upstands and drainage outlets, since these change the material count far more than the flat area does. They also need to find out whether the existing membrane is lifting, blistered or split, whether there is trapped moisture under it, and whether a previous coating will need removing before the new layers go down. Access arrangements, the condition of the parapet walls and the position of any water tanks, which can be coated internally at SAR 25–60 per m² where they are fitted, are all noted on site and not guessed from a distance. Where cracks run through a substrate, crack injection at SAR 40–120 per metre may be needed, and the length of each crack is measured in person.

For the technician's benefit, it helps to arrive with the property's approximate roof dimensions, a note of how the building is used, and any photographs of leak points taken after recent rain. A bitumen membrane is quoted at SAR 15–35 per m², and the final figure depends on the measured area, the number of upstands and whether insulation is involved, since XPS boards at SAR 12–30 per m² are sometimes laid beneath a new surface. Knowing the age of the building and any earlier repairs lets the technician plan the work sensibly. Clear information at the start means the visit can focus on what really needs checking rather than repeating basic questions.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs that call for bitumen membrane

If you notice one of these signs in Yanbu, it is a good moment to talk to the team:

• A flat concrete roof that needs waterproofing
• Old rolls that are cracking

Where the problem usually comes from

• A common cause: no protection layer.
• Seams that were not welded properly.

How we choose the tool in Yanbu

The steps in order

1. Preparation: Cleaning, priming and repairs.
2. Torch welding: Overlaps are welded and checked.
3. Details: Upstands, drains and bases.
4. Protection and flood test: Protection is laid after a successful flood test.
