Bitumen membrane for clinics in Aljumum
In short: In Aljumum (Aljumum), bitumen membrane for clinics begins with the roof, falls and drains survey and the flood test; nothing is opened until the position is clear. The centre of Aljumum sits about 200 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.
Before we start: what we know about Aljumum
Team note on Aljumum: 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..

Bitumen membrane work for clinics in Aljumum starts with the basics of the site. The centre of Aljumum sits about 200 m above sea level (SRTM open elevation data), so a technician should look at how rainwater will run off a roof and down the surrounding ground before anything else is planned. Clinics often have flat roofs with plant rooms, lift overruns and rooftop equipment, and each of these creates a joint or upstand that needs careful sealing. Bitumen membrane for roofs is usually priced at SAR 15–35 per m², and that range is a useful starting point when comparing options, but the final figure depends on what the surface needs.
Some things can only be settled on the site visit. The technician needs to see the existing roof build-up, check whether any old membrane is still bonded or has blistered, and note where water has been pooling. Drainage outlets, parapets, pipe penetrations and the condition of the screed all affect how the new membrane should be laid. If cracks are present, their length will decide whether crack injection (SAR 40–120 per m) is needed before the membrane goes down. Access arrangements also matter in a clinic, because patient areas and sterile zones must be kept clear of noise, fumes and dust during the work.
For the technician, it helps to arrive with a clear record of the building's use and layout. Ask the clinic for the roof plan, any previous repair records, and the times when work will least disrupt patients. Measure the roof area accurately and mark every upstand, drain and joint on the plan. If the roof is being combined with other protection, such as XPS boards (SAR 12–30 per m²) for insulation or liquid roof waterproofing (SAR 8–25 per m²) for small detail areas, note this on the quote so the scope is clear. A careful survey at the start saves rework later and gives the clinic a roof that stays watertight.
For clinics, work is scheduled around patient hours and kept to the areas that need it.
When do you need bitumen membrane?
The following signs are worth checking before they grow:
- 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.
- A common cause: no protection layer.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| 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 |
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.
