Spray foam insulation in Aljumum: the local context

Team note on Aljumum: 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 Aljumum sits about 200 m above sea level (SRTM open elevation data).

Aljumum sits at a height of about 200 m above sea level, which is the first thing we check on any spray foam job here. At that elevation the air and surfaces can differ from coastal sites, so the technician confirms the substrate is dry and sound before any foam goes on. Spray foam for hotels and serviced apartments is priced at SAR 20–45 per m², and the final figure depends on what the surface needs, so we look at the existing condition first rather than quoting from the area alone.

What is left to the site visit is the detail that cannot be known from a distance. The technician walks the ceilings, roof voids and external walls to judge the thickness required, the access available, and whether any cracks need attention first. Crack injection is charged at SAR 40–120 per metre, so the length and location of cracks are measured on site. Where a roof is involved, liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m² are compared against the roof's age and use, and the choice is made in person. Basements, bathrooms and water tanks are treated the same way, with each area inspected for moisture before a method is agreed.

Information that helps the technician is simple to gather in advance. Please note which rooms are occupied during the work, since serviced apartments and hotel floors often need phased scheduling, and mention any past leaks, damp patches or noticeable temperature changes in upper floors. Tell us the rough area of each zone and whether a basement, bathroom or tank is included, because basement waterproofing (SAR 50–150 per m²), epoxy coating (SAR 35–90 per m²) and XPS boards (SAR 12–30 per m²) each change the approach. Clear access routes and a contact on site will keep the visit short and the scope accurate.

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