Why spray foam insulation differs in Aldarb

Aldarb is about 18.7 km from the sea coast (OpenStreetMap). The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data).

Spray foam work in Aldarb starts with the building's position, because that shapes what needs attention first. The centre of Aldarb sits about 79 m above sea level, and the town is about 18.7 km from the sea coast. Those facts mean the site is inland and elevated, so the first checks focus on the building envelope itself, such as walls, roof edges and openings, rather than on salt exposure or low-lying ground water. Spray foam is priced at SAR 20–45 per m², so the first survey is used to measure the exposed surface accurately and confirm which areas will actually receive foam.

Several things are left to the site visit, because they cannot be judged from a distance. The technician needs to see the wall construction, the condition of existing sealants, any cracks that may need crack injection at SAR 40–120 per metre, and whether a roof area is better served by liquid roof waterproofing at SAR 8–25 per m² or by an XPS board layer at SAR 12–30 per m². Basement and bathroom areas, where basement waterproofing (SAR 50–150 per m²) or bathroom waterproofing (SAR 15–40 per m²) may be relevant, should be inspected on foot. The visit is also the place to note any water tank that might need internal coating at SAR 25–60 per m², or a bitumen membrane at SAR 15–35 per m² on a flat roof.

Information that helps the technician arrive prepared includes a plan of the building with each room and floor level marked, the approximate age of the structure, and any past repairs or leaks that the occupants remember. Access details matter as well, such as which rooms can be emptied, when the occupants are at home, and where power and water are available on site. Photographs of problem areas sent in advance let the technician estimate materials and time more accurately. A short note on the intended use of each room, whether living space, storage or a wet area, also helps match the right product to the right surface.

For a whole building, a survey of the shared systems comes before unit-by-unit work.
