What is specific about Almuzahimiyah for bitumen membrane
The centre of Almuzahimiyah sits about 889 m above sea level (SRTM open elevation data).
Consider a restaurant owner in Almuzahimiyah who runs a busy kitchen and dining room under a flat concrete roof. Between the daily cooking, the grease-laden air, the staff traffic, and the storage of heavy equipment above, the roof is quietly taking a beating. Water that finds a small gap in the membrane can travel along the slab and reach the ceiling of the dining area or the stock room below, often before anyone notices a stain. For a food business, a leak is not only a repair bill but a risk to hygiene inspections and to the day's trade.
The Almuzahimiyah area sits about 889 m above sea level, which places it in a higher, drier part of the Saudi landscape where sun exposure on an exposed roof is intense for much of the year. Heat and strong daylight cause bitumen to soften, dry out, and crack over time, and expansion and contraction between hot afternoons and cooler nights open hairline gaps at joints and around rooftop fixtures. A bitumen membrane, typically priced in the range of SAR 15–35 per m², remains one of the practical choices for this kind of flat roof because it forms a continuous sheet that can be applied in layers. Owners should also budget for related works such as liquid roof waterproofing at SAR 8–25 per m² for smaller areas, and crack injection at SAR 40–120 per metre where cracks run through the concrete beneath the membrane.
For a restaurant owner planning this work, start by having the roof surveyed for existing cracks, ponding areas, and failed sealant around drains, air-conditioning units and exhaust fittings. Next, measure the roof area in square metres so that membrane and any extra thermal insulation can be priced accurately, and consider XPS boards at SAR 12–30 per m² if the roof space is used and needs insulation. Schedule the work during a period that suits your trading calendar, so that the kitchen can keep operating or closes for the shortest possible time. Finally, confirm in writing the scope, the materials and the warranty terms before the first layer goes down, and keep records of the work for future maintenance and inspections.
For restaurants, visits are planned outside service hours and recorded for the premises file.

Questions from Almuzahimiyah
Does an old building need the old roof surface removed before insulation?
It depends on the condition of the roof surface and the type of insulation chosen. If the surface is sound, the insulation is applied over it after cleaning and treatment, and if it is damaged, the contractor may recommend repairing it or removing the damaged layers first.
Does spray foam need a protective coating after application?
Yes, an acrylic or similar protective coating is applied to shield the foam from sunlight. This coating is essential for maintaining insulation efficiency and extending its lifespan.
How do I know the right type of insulation for my water tank?
The type is determined by whether the tank is underground or overhead and the water usage. Drinking water tanks are usually insulated with safe materials like epoxy or specialized cement after contractor inspection.
