Bitumen membrane in Samtah: before buying or handover
In short: Bitumen membrane (before buying or handover) in Samtah starts with the roof, falls and drains survey, then the flood test, before anything is opened. The centre of Samtah sits about 61 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.

Samtah sits at about 61 m above sea level, and its centre is roughly 22.6 km from the coast. For a bitumen membrane job, those two facts shape what a technician looks at first. A site at this height and distance from the sea is not treated as a seaside case, but the roof, slab or basement still needs a careful look at its drainage, its existing layers and any signs that water has been moving through the structure. Before you buy or accept a handover, ask the installer to confirm the surface is sound and that water has a clear route off the roof.
Several checks are best left to the site visit itself, because they cannot be judged from a brochure or a phone call. The technician should walk the surface, note any cracks, blisters or ponding areas, and check the upstand heights and the edges where the membrane meets walls, pipes and drains. They should also confirm the substrate is dry and clean enough to take the membrane, and that the existing finish has not lifted. Measurements should be taken on the spot, since the area in square metres and any linear metres of joints or cracks drive the quote. A visit also lets the crew see access, timing constraints and whether the building is occupied during work.
To help the technician prepare, gather the basic information before they arrive: the age of the roof or structure, any previous waterproofing and its type, and a note of where leaks have appeared inside the building. Photos of problem areas, the roof plan or sketch, and the location of drains, outlets and rooftop fixtures all save time. Tell them whether the surface is to be used as a walkway or a plant area, since that affects the finish chosen. A clear record of these details lets the technician give you an accurate scope and a realistic estimate for your Samtah property.
Before buying or taking over a property, an inspection gives you findings in writing before you sign.
When do you need bitumen membrane?
These are the signs most often linked to bitumen membrane:
- 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.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| 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.

Planning the visit in Samtah
- 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).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- 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.
