Bitumen membrane in Alqunfudhah: the local context

The centre of Alqunfudhah sits about 7 m above sea level (SRTM open elevation data). Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

Team note on Alqunfudhah: 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..

Alqunfudhah sits on low ground, with the centre about 7 m above sea level, and the town lies roughly 0.4 km from the coast. For a bitumen membrane service, these two facts matter more than they might seem. Water does not drain away quickly from a site this close to the sea and this near to ground level, so rainwater and groundwater tend to pool on flat roofs and around foundations for longer. That makes an emergency call more likely after a storm, and it means the crew needs to check ponding and drainage outlets before laying anything new.

The short distance to the coast also means the air carries salt and moisture, which affects how a membrane bonds and cures. Surfaces here often hold damp and salt residue, so the first step on site is to clean and dry the substrate properly before the bitumen is applied. The low elevation adds a second concern: water that cannot run off will work into joints and upstands, so the team focuses on sealing laps, parapets and penetrations where leaks most often start. Bitumen membrane for roofs is typically priced at SAR 15–35 per m², and an emergency visit is usually scoped by how much area is affected and whether the leak is at a single point or across the whole roof.

Owners in Alqunfudhah often make the same few mistakes, and avoiding them saves time and money. The first is waiting until the ceiling is stained before calling, by which point water has already travelled into the structure. The second is patching a leak without checking the surrounding membrane, so the new repair fails at the edge of the old one. The third is blocking or ignoring roof drains, which lets water stand and push under the membrane. The fourth is painting over damp surfaces, which traps moisture and causes the coating to lift. Clearing drains, reporting leaks early and letting the crew dry the surface before work begins are the simplest ways to keep an emergency repair from becoming a larger job.

If water is flowing, close the main valve first, then call or message with photos.

When do you need bitumen membrane?

If you notice one of these signs in Alqunfudhah, it is a good moment to talk to the team:

• 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 Alqunfudhah

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.
