Picture the owner of a warehouse in Al Mrwj who wants the building to stay cool and dry through the summer. The roof takes the full force of the afternoon sun, and the walls heat up quickly, so the inside can become uncomfortable for staff and stock. This owner is usually looking for a way to reduce heat gain without shutting the building down for weeks, and wants a clear sense of what the work will involve before anyone starts.
Al Mrwj sits roughly 5 km from the centre of Riyadh, and its centre lies at 24.7578, 46.6637. The neighbourhood mixes villas and apartment buildings, so warehouse owners here often share streets with homes and need to plan work that keeps noise and access manageable. The area is about 635 m above sea level, and the nearest wadi channel runs about 2.8 km from the centre, which is a reminder that rain can arrive in short, heavy bursts. For a warehouse, that means the roof and the lower walls should be checked for water paths, and any insulation layer should be sealed so that moisture does not get trapped against the structure.
Spray foam insulation is one of several options, typically priced at SAR 20–45 per m². Start by inspecting the roof and walls to identify cracks and damp patches, and note where the exposed surfaces are most affected by sun. Next, repair any cracks with crack injection, which is priced at SAR 40–125 per metre, so the surface is sound before the foam goes on. Then apply the spray foam evenly, and finish the roof with liquid roof waterproofing at SAR 10–25 per m² if the layout calls for it. Finally, record the completed areas and schedule a follow-up check after the first rainy period, so any small issue is caught early.
For warehouses, work is phased around operations and stored goods.

Tools we use in Al Mrwj
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Thickness measurement at spread-out points | Whether the thickness in the quote was achieved | Limits: for foam and liquid-applied layers |
How the work is done, step by step
- Survey: Joints, fixings and gutters are checked.
- Preparation: The surface is cleaned and dried.
- Spraying in layers: Foam is applied in passes to the agreed thickness.
