What is specific about Abu Arish for bitumen membrane

The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data). Team note on Abu Arish: 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..

For hotels and serviced apartments in Abu Arish, the most common problem with bitumen membrane work on flat roofs is water tracking into the upper floors through worn or poorly lapped sheets, often around parapets, drains and roof penetrations. Guests notice stains on ceilings long before the source is found, and by then the damage has spread into insulation and finishes. Because these buildings rely on continuous occupancy, owners want the fix to be planned around room bookings rather than carried out as an emergency.

The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data), which means the site is not in a low-lying basin where ground water collects. That changes the approach: the priority is shedding rain from the roof quickly and protecting the roof edges and drainage outlets rather than focusing on standing water at foundation level. Bitumen membrane is priced at SAR 15–35 per m², which fits the large, mostly flat roof areas typical of these buildings. For areas with more complex detailing, liquid roof waterproofing at SAR 8–25 per m² is a lower-cost option to compare, while XPS boards at SAR 12–30 per m² can be considered where thermal performance above the waterproofing is also a concern. Crack injection at SAR 40–120 per m is worth pricing separately if cracking is found in parapet walls or roof upstands.

Before the visit, ask the service provider to confirm the roof area and the number of drainage outlets, parapets and penetrations, since these drive both the membrane quantity and the detailing time. Ask whether the work can be phased floor by floor or wing by wing so rooms stay available, and whether they will inspect the existing membrane for blistering or lifting before quoting. Request a written breakdown showing the rate per m² and any separate items for crack injection or edge detailing, so you can compare quotes on the same basis.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

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

Where the problem usually comes from

• No protection layer — we check this before anything else.
• Seams that were not welded properly — we check this before anything else.

Tools and methods, and when we use them

The steps in order

1. Preparation: Cleaning, priming and repairs.
2. Torch welding: Overlaps are welded and checked.
3. Details: Upstands, drains and bases.
4. Protection and flood test: Protection is laid after a successful flood test.
