Bitumen membrane in Rastanura: with a verifiable technical report

Before we start: what we know about Rastanura

Team note on Rastanura: 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.. Rastanura is about 0.2 km from the sea coast (OpenStreetMap).

Rastanura sits about 0.2 km from the sea coast, according to OpenStreetMap, and that short distance shapes what a technician looks at first. A property this close to the shore is exposed to salt-laden air and moisture that can work into surfaces over time, so the first check is usually the condition of the existing membrane or the substrate beneath it, along with any signs of salt staining, blistering or lifting at the edges. Because bitumen membrane is priced at SAR 15–35 per m², the inspection focuses on whether the area can take a new membrane at all, or whether surface preparation will add to the scope before the material is even laid.

Some things cannot be judged from a distance and are left to the site visit. The technician needs to walk the roof or the affected area, measure the true surface area in square metres, identify any cracks, and decide whether joints and upstands need separate treatment. Crack repairs are priced separately at SAR 40–120 per metre, so the length and location of cracks changes the quote noticeably. Drainage outlets, parapets and the state of the substrate underneath are also assessed on the spot, since none of these can be confirmed from a written description alone.

To help the technician, it is useful to have a few details ready before the visit. Note the approximate roof or area size, any past leaks and where they appeared, and whether a previous waterproofing layer was installed and when. Photos of the surface, especially close-ups of cracks and edges, speed up the assessment. If the area is not a roof but a basement, bathroom or tank, say so at the start, because the material and the rate differ: basement work is SAR 50–150 per m², bathroom work SAR 15–40 per m², and tank interior coating SAR 25–60 per m². Clear information at the start means the visit can focus on what matters.

Each job ends with a written report that carries a verification code you can check on our site.

Signs worth paying attention to

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

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

Causes we see in the field

• Seams that were not welded properly — we check this before anything else.
• A common cause: no protection layer.

Tools and methods, and when we use them

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.
