Bitumen membrane for restaurants in Madinah
In short: Bitumen membrane for restaurants in Madinah starts with the roof, falls and drains survey, then the flood test, before anything is opened. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Pricing starts from Bitumen membrane (per m²) (SAR 15–35 per m²), and other items are quoted after the visit.
Why bitumen membrane differs in Madinah
The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Team note on Madinah: 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..
Madinah's city centre sits about 589 m above sea level, so the first thing a technician checks on a restaurant roof is how water will run off and where it will collect. Because the site is at this elevation, rain that falls on a flat roof pools at low points and at the edges of kitchen extraction and plant platforms rather than draining away on its own. Before any membrane is priced, the crew walks the full roof, notes every low spot, and confirms that the falls toward the outlets are real and not just assumed. Restaurant roofs also carry heavy equipment, grease-laden vents and foot traffic from staff, all of which stress the surface, so the check covers old patches, lifting laps and any places where the existing membrane has already split.
Some things can only be settled on the site visit. The crew needs to see the deck condition under the old layer, whether there is moisture trapped in the substrate, how the parapets and upstands are finished, and where pipes, cables and ducts pass through the roof. The condition of the drainage outlets and whether they are clear of debris are judged on the spot, as is the access route for materials. Measurements are taken for the actual roof area and any upstands, because a bitumen membrane is priced per square metre, currently at SAR 15–35 per m², and the final quote depends on what is really there. Tank and basement areas, if they are part of the same job, are assessed separately because they use different products and rates.
To help the technician, it is useful to have the roof plan or a rough sketch ready, along with the date the current covering was laid and any history of leaks inside the kitchen or dining area. Note whether the restaurant can close the roof area during works, and at what times, since bitumen work needs a dry, settled surface and clear working hours. Photos of ponding after rain and of any stains on ceilings below are very helpful. Knowing which outlets block most often lets the crew plan cleaning before the membrane goes down. With this information gathered in advance, the visit moves faster and the scope is more accurate.
For restaurants, visits are planned outside service hours and recorded for the premises file.
When do you need bitumen membrane?
The following signs are worth checking before they grow:
- A flat concrete roof that needs waterproofing
- Old rolls that are cracking
Where the problem usually comes from
- No protection layer.
- Seams that were not welded properly — we check this before anything else.
Tools and methods, and when we use them
| Tool | What it finds | When we use it in Madinah |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
How the work is done, step by step
- 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.

Common questions about bitumen membrane in Madinah
What is the difference between standard spraying and integrated pest management?
Standard spraying treats visible symptoms only, while integrated pest management includes diagnosis, sealing entry points, and multiple methods for longer-lasting results.
Could the leak be caused by weak waterproofing rather than the pipes?
Yes, damage to the waterproofing layer beneath the bathroom floor is one of the most common causes of leaks, especially in older buildings. In this case, water seeps through the tile joints into the screed and then down to the ceiling below. A specialized inspection can distinguish this from a pipe leak.
What is the difference between drain unblocking and drain cleaning?
Unblocking removes an existing blockage that prevents drainage, while cleaning is a preventive procedure that removes deposits and grease from pipes before they cause a blockage.
Where does bitumen membrane for restaurants start in Madinah?
