The centre of Tabarjal sits about 548 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.
What is specific about Tabarjal for bitumen membrane
The centre of Tabarjal sits about 548 m above sea level (SRTM open elevation data). Team note on Tabarjal: 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..
Picture the owner of a small office block or commercial complex in Tabarjal, responsible for a flat roof that has to keep tenants dry through the year. Water finds the weak points first: a lapped seam, a worn corner at a parapet, or a drain that no longer sheds properly. By the time a stain appears on a ceiling below, the problem has usually been building for some time. The owner wants a roofing approach that is durable, priced clearly, and planned so that work does not disrupt the businesses operating beneath it.
Tabarjal sits at roughly 548 m above sea level, which places it on the higher ground of the region. For a bitumen membrane on an office or commercial roof, that elevation is a reason to pay close attention to how water is drained away from the surface, since rainwater collects and moves quickly on a sloped site. The bitumen membrane in this range costs about SAR 15–35 per m², which makes it a sensible option when a roof covers a large, consistent area. Where ponding or leaks are limited to a single line, crack injection at SAR 40–120 per metre may be a more targeted first step, and liquid roof waterproofing at SAR 8–25 per m² can suit surfaces that need a seamless finish.
A practical sequence helps keep the project controlled. First, survey the roof and mark every drain, upstand, crack, and area of standing water. Second, decide whether the existing layers can be overlaid or must be cleaned back to a sound base, and budget accordingly. Third, repair cracks and loose edges before the membrane goes down, because a membrane cannot bridge a moving or damaged substrate. Fourth, apply the bitumen membrane in the planned layers, with laps and upstands sealed properly. Finally, test the drainage with water after completion and record the work so future inspections have a clear baseline. Carrying out these steps in order protects both the building and the tenants.
For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.
Signs worth paying attention to
If you notice one of these signs in Tabarjal, it is a good moment to talk to the team:
- 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.
Tools and methods, and when we use them
| Method | What it helps with | Its role in Tabarjal |
|---|---|---|
| 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.
