Before we start: what we know about Tarout

Main roads in or near Tarout: Uhud Road, Al Khaleej Road, Al Aimmah Bridge. Team note on Tarout: 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..

Tarout is about 0.9 km from the sea coast (OpenStreetMap). The centre of Tarout sits about 3 m above sea level (SRTM open elevation data).

Is a bitumen membrane the right choice for a hotel or serviced apartment building in Tarout? Owners here often ask this because the town sits low and close to the water. The centre of Tarout sits about 3 m above sea level, and it is about 0.9 km from the sea coast. Those two facts mean roofs, podiums and below-grade areas can face damp air and standing water after heavy rain, so a reliable waterproofing layer matters. Bitumen membrane is priced at SAR 15–35 per m², which places it in the mid range among the options we cover, alongside liquid roof waterproofing at SAR 8–25 per m² and XPS boards at SAR 12–30 per m².

Our inspection for a hotel or serviced apartment block begins with a walk over the roof and any exposed deck, looking for cracks, lifted laps, ponding areas and old patches. The team then checks the surfaces that will receive the membrane, noting where a crack may need injection at SAR 40–120 per metre before the new layer goes down. Where the building has a tank, the inspector also notes its internal condition, since tank internal coating is priced at SAR 25–60 per m². The findings are recorded by area so the owner can compare options, whether the work is limited to the roof or extends to basements, bathrooms or epoxy-coated floors. Each area is measured so the quote reflects the real surface, not an estimate.

Before the visit, please prepare a plan or sketch of the building showing roof areas, stairwells, plant rooms and any basement level. Note the years of previous repairs and any leaks reported by guests or tenants, and mark the rooms where damp has appeared. Clear access to the roof hatch and the parapets, and tell us which days suit the hotel or apartment occupancy so the inspection does not disrupt guests. Having these details ready helps the team arrange the right crew and gives you a clear, written scope before any work starts.

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