Bitumen membrane in Qatif: for companies (annual contract)
In short: In Qatif (Qatif), 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 Qatif 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 Qatif
The centre of Qatif sits about 5 m above sea level (SRTM open elevation data). Qatif is about 2.5 km from the sea coast (OpenStreetMap).

Qatif sits on low, flat ground in Saudi Arabia's Eastern Province, with the centre about 5 m above sea level, and the coast lies roughly 2.5 km away. For a company with a bitumen membrane contract, these two facts shape the work. Sites this close to the sea and this near the water table can see groundwater pressing against slabs and walls, so the membrane must be chosen and laid to hold back water from below, not just from above. Our crews check drainage paths and ground conditions before they begin, because a membrane is only as sound as the surface it bonds to.
The flat, low character of the area also means rainwater tends to pool rather than run off quickly. Roofs, podiums and tank lids on commercial buildings therefore need a continuous membrane with properly lapped and sealed edges, and falls should be confirmed so water drains toward outlets. On an annual contract, we schedule inspections around these conditions so that ponding, blocked outlets and worn upstands are caught early, before they turn into leaks through ceilings and stock.
Owners who keep their membranes performing for years tend to avoid a few common mistakes. They do not treat a bitumen membrane as a one-time job and then forget it; they agree on regular checks and prompt repairs. They do not let plant, cables or foot traffic damage the surface without protection, and they do not allow cracks in the substrate to be covered over without first being repaired. They also avoid pricing the work only by area, since the detailing at drains, joints and penetrations decides how well the whole system performs. Reviewing these points with our team at the start of the contract keeps the membrane doing its job for the full term.
For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
Signs that call for bitumen membrane
These are the signs most often linked to bitumen membrane:
- A flat concrete roof that needs waterproofing
- Old rolls that are cracking
Where the problem usually comes from
- No protection layer — we check this before anything else.
- A common cause: seams that were not welded properly.
How we choose the tool in Qatif
| Method | What it helps with | Its role in Qatif |
|---|---|---|
| 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.

Practical notes for residents of Qatif
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
