Is spray foam insulation worth it for a restaurant in Zhra Lbn, Riyadh? For most owners the answer depends on the kitchen and cold-room walls, the roof, and how much heat the building takes in. Zhra Lbn sits at about 24.6329, 46.5531, roughly 15.3 km from the centre of Riyadh, with an approximate radius of 8 km. Its centre lies about 747 m above sea level, and the nearest wadi channel is about 1.8 km away. Spray foam typically costs SAR 20–45 per m², which places it among the mid-range options alongside XPS boards at SAR 15–30 per m² and liquid roof waterproofing at SAR 10–25 per m². Owners comparing insulation with waterproofing should note that crack injection is priced at SAR 40–125 per metre, so any existing wall or slab defects may need sealing first.

Our inspection for a restaurant site in Zhra Lbn begins with a walk-through of the kitchen, dining room, cold store and roof to record exposed wall areas, roof area and any visible cracks or damp patches. The technician then checks how the existing surfaces are finished and whether earlier coatings or membranes are still sound. Where moisture is suspected, readings are taken at several points so the problem is traced before any material is chosen. The inspector then measures the areas that would receive spray foam and estimates the work in square metres, with separate lines for any crack injection, basement or bathroom waterproofing, epoxy coating on floors, or tank lining if the site has one. The result is a written breakdown that shows which items are needed and which can wait.

Before the visit, gather the building's floor plans or a simple sketch with dimensions, and note which rooms run hot, such as the kitchen, bakery area or rooms beneath the roof. Tell the inspector about any leaks, stains or cracks you have seen, and when they first appeared. Clear access to the roof hatch, the cold room and any basement or storage space so the team can work without delay. If a previous contractor did earlier waterproofing, bring their records. Having this information ready helps the inspection cover the right areas and gives you a clearer picture of what the work will involve.

For restaurants, visits are planned outside service hours and recorded for the premises file.
