Bitumen membrane in Taif: with a verifiable technical report

What is specific about Taif for bitumen membrane

The centre of Taif sits about 1673 m above sea level (SRTM open elevation data). Team note on Taif: 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..

Taif sits at the centre of the Hijaz mountains, with the city centre about 1673 m above sea level (SRTM open elevation data). That height matters for waterproofing. Cooler nights and larger day-to-night temperature swings cause roofs, walls and slabs to expand and contract more often, which stresses joints and seams. Bitumen membrane, priced at SAR 15–35 per m², is a flexible sheet that can move with the structure, so it suits roofs and below-ground surfaces where this movement is most noticeable.

Each feature of the area has a direct effect on how the work is planned. Because the centre is at this altitude, the crew checks substrates for hairline cracks before laying anything, and any crack is treated first, since crack injection is priced at SAR 40–115 per metre and must be finished before the membrane goes down. Where a building has a basement, basement waterproofing at SAR 50–145 per m² is planned together with the membrane so that the lower walls and slab are sealed against groundwater. For roofs, liquid roof waterproofing at SAR 10–25 per m² is sometimes compared with bitumen, but the sheet system is usually chosen where a continuous, thicker layer is needed. Surfaces are dried and primed so the bitumen bonds properly, and the layers are overlapped at seams and upstands.

Owners often avoid the same avoidable problems by following a few habits. They do not skip the substrate check, because a membrane laid over a cracked or damp base will fail early. They do not accept a quote that leaves out crack repair, primer or upstand detailing, since these items are what hold the system together. They do not compare only the price per square metre, because a cheaper sheet that is laid carelessly costs more to repair than a properly installed one. And they ask for a written technical report listing the surfaces, measurements, materials and steps used, so the work can be checked later against what was agreed.

Each job ends with a written report that carries a verification code you can check on our site.

Signs worth paying attention to

The following signs are worth checking before they grow:

• A flat concrete roof that needs waterproofing
• Old rolls that are cracking

Causes we see in the field

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

Tools we use in Taif

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.
