Before we start: what we know about Hafr Albatin

Team note on Hafr Albatin: 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.. The centre of Hafr Albatin sits about 312 m above sea level (SRTM open elevation data).

Hafr Albatin sits in the north-east of the Eastern Province, and the centre of the town is about 312 m above sea level, according to SRTM open elevation data. That modest height means the town is not in a mountainous zone, but it still receives heavy seasonal rainfall in short bursts, and water tends to pool on flat roofs and in low corners rather than run away quickly. For companies that run warehouses, workshops, staff housing or small plants here, this is the reason roof and slab protection matters most. Our bitumen membrane service for companies is built around that exposure, with the membrane laid to fall toward drainage outlets so standing water does not sit on the surface for long.

Each part of the site is linked to a practical effect on the work. A bitumen membrane is priced at SAR 15–35 per m², and the figure depends on the roof area, the number of upstands and penetrations, and how many layers the surface requires. On a flat industrial roof, the membrane is the main barrier between rainwater and the structure beneath, so we start every annual contract with a survey of drains, parapets and pipe penetrations. Where a company also has water tanks or basement store rooms, the same contract can include tank internal coating at SAR 25–60 per m² and basement waterproofing at SAR 50–150 per m², so the whole building is covered under one agreement. Where roof insulation is needed, XPS boards at SAR 12–30 per m² can be fitted beneath the membrane to reduce heat gain from the roof.

Owners who choose this service on an annual contract tend to avoid a few common mistakes. The first is laying a new membrane over a surface that has not been cleaned or dried, which traps moisture and causes blistering within a season. The second is leaving drains and outlets blocked by sand or debris, so the membrane is tested by water it was never designed to hold. The third is treating small cracks at parapets or joints as cosmetic and delaying crack injection, priced at SAR 40–120 per metre, until water has already reached the interior. The fourth is scheduling work in the middle of a rainy period, when the surface cannot be prepared properly. A yearly contract lets the team inspect each roof before the wet season, repair early, and keep records for the company's maintenance plan.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
