Bitumen membrane for schools in Alula
In short: In Alula (Alula), bitumen membrane for schools begins with the roof, falls and drains survey and the flood test; nothing is opened until the position is clear. The centre of Alula sits about 697 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 Alula
The centre of Alula sits about 697 m above sea level (SRTM open elevation data). Main roads in or near Alula: King Abdullah Road.
Picture a school operator in Alula who manages a single-storey building with a flat roof, a few courtyards, and a water tank on the grounds. Summers are hot and dry, but the building still faces the occasional heavy shower, and maintenance budgets are tight. Their main concern is keeping classrooms dry and avoiding leaks that disrupt lessons and damage ceilings, without paying for work that the building does not need.
The local facts shape how this owner should think about bitumen membrane. The centre of Alula sits about 697 m above sea level, which places it in a high desert setting where roofs are exposed to strong sun and wide temperature swings. Bitumen membrane is priced at SAR 15–35 per m², making it one of the more affordable roof options when set against spray foam at SAR 20–45 per m² or epoxy coating at SAR 35–90 per m². For a flat school roof, a membrane system is therefore a sensible starting point, while more expensive options should be reserved for areas that truly need them, such as the basement at SAR 50–150 per m² if one exists.
Practical steps follow in order. First, walk the roof after rain and mark every ponding area, crack, and lifted seam. Second, check the membrane edges, upstands, and drains, since most leaks start at junctions rather than the open field. Third, measure the roof area and separate it into zones so the quote covers only what is needed. Fourth, ask for a written scope that lists the membrane type, the surface preparation, and how cracks will be treated, including any crack injection at SAR 40–120 per metre. Fifth, schedule the work during school holidays so classrooms stay usable. Finally, keep a simple log of inspections so the next repair is planned, not reactive.
For schools, the larger jobs are planned for weekends and holidays.
Signs worth paying attention to
The following signs are worth checking before they grow:
- A flat concrete roof that needs waterproofing
- Old rolls that are cracking
Causes we see in the field
- A common cause: no protection layer.
- Seams that were not welded properly — we check this before anything else.
How we choose the tool in Alula
| Tool | What it finds | When we use it in Alula |
|---|---|---|
| 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.
