Bitumen membrane in Alqunfudhah: without breaking
In short: In Alqunfudhah (Alqunfudhah), bitumen membrane (without breaking) begins with the roof, falls and drains survey and the flood test; nothing is opened until the position is clear. Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap). Pricing starts from Bitumen membrane (per m²) (SAR 15–35 per m²), and other items are quoted after the visit.
Bitumen membrane in Alqunfudhah: the local context
Team note on Alqunfudhah: 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.. Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).
The centre of Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).
Alqunfudhah sits about 7 m above sea level, and its centre is roughly 0.4 km from the coast. That combination matters for a bitumen membrane job. Low, close-to-sea sites see salt-laden air, warm days and sudden rain, and a roof that is only a little above the water table can hold moisture under its surface. Our crews check the substrate for dampness before any membrane goes down, because a membrane laid over trapped moisture will blister and lift.
Each of these local conditions has a direct effect on the work. Because the ground is close to sea level, we look closely at drainage outlets, parapets and the edges where water is most likely to pool or run back under the membrane. The coastal air means we pay attention to the lap joints and terminations, since salt and heat are harder on loose edges than on well-sealed ones. For bitumen membrane in particular, the price for the work is set per square metre, in a range of SAR 15–35 per m², and the final figure depends on the state of the existing surface, the detailing around penetrations and the number of layers needed to keep the roof sound.
Owners in Alqunfudhah often avoid a few common mistakes with the help of a proper survey. The first is laying new membrane over a surface that was never cleaned or primed, which traps dust and moisture beneath it. The second is ignoring small cracks, which are cheaper to treat early than after water has travelled into the structure. The third is sealing the edges and then forgetting the drainage, so that standing water simply finds a new route. Taking these points into account before the work begins keeps the membrane doing its job for longer, with less disruption to the building.
The aim is to locate the cause with instruments first, so any opening is limited to one point.
Signs worth paying attention to
These are the signs most often linked to bitumen membrane:
- Old rolls that are cracking
- A flat concrete roof that needs waterproofing
The most common causes
- Seams that were not welded properly — we check this before anything else.
- No protection layer.
Tools we use in Alqunfudhah
| Method | What it helps with | Its role in Alqunfudhah |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
The steps in order
- Preparation: Cleaning, priming and repairs.
- Torch welding: Overlaps are welded and checked.
- Details: Upstands, drains and bases.
- Protection and flood test: Protection is laid after a successful flood test.
