Bitumen membrane in Allith: for companies (annual contract)
In short: In Allith (Allith), bitumen membrane (for companies (annual contract)) begins with the roof, falls and drains survey and the flood test; nothing is opened until the position is clear. The centre of Allith sits about 5 m above sea level (SRTM open elevation data). Published price: Bitumen membrane (per m²), SAR 15–35 per m²; anything else is quoted after the inspection.
Why bitumen membrane differs in Allith
Main roads in or near Allith: Al Laith Road, Amr Bin Al Aas Street. The centre of Allith sits about 5 m above sea level (SRTM open elevation data).
Allith is about 1.2 km from the sea coast (OpenStreetMap).
For a company that owns a commercial building in Allith, the roof is often the largest single area to protect, and it usually carries the most weight in the building's day-to-day operations. A typical scenario is a facilities manager responsible for a warehouse, office block or small factory who wants to avoid sudden leaks that interrupt stock, staff and customers. The usual approach is to set up an annual contract with a waterproofing contractor, so that inspection and repair are planned rather than reactive.
Allith sits about 5 m above sea level and roughly 1.2 km from the coast. For a business owner, these two facts mean that the roof is exposed to a humid, salt-laden air, and that rainwater and surface moisture have little natural fall to drain away quickly. Bitumen membrane is a sensible option for flat or low-slope roofs in this setting because it forms a continuous layer over the whole surface. Its cost in the range of SAR 15–35 per m² gives a company a clear budget basis when comparing it with liquid roof waterproofing at SAR 8–25 per m² or with other systems. Because membranes can be damaged at joints and upstands, an annual inspection is the most practical way to catch small faults early.
The first step is to measure the roof area and note its drainage points, parapets and any rooftop equipment that needs sealing. The second is to ask the contractor for an inspection of the existing surface, including any crack injection needs, which are priced at SAR 40–120 per metre. The third is to agree the scope of the annual contract, stating when inspections happen and how urgent repairs are reported and handled. The fourth is to keep a simple record of each visit, so that the company can see how the membrane is performing over time and plan any larger renewal well in advance.
For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
Signs worth paying attention to
These are the signs most often linked to bitumen membrane:
- A flat concrete roof that needs waterproofing
- Old rolls that are cracking
The most common causes
- No protection layer.
- A common cause: seams that were not welded properly.
Tools and methods, and when we use them
| Method | What it helps with | Its role in Allith |
|---|---|---|
| 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 |
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.
