Spray foam insulation in Jubail: the local context

Team note on Jubail: 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.. Jubail is about 0.9 km from the sea coast (OpenStreetMap).

The centre of Jubail sits about 4 m above sea level (SRTM open elevation data).

Jubail sits only about 4 m above sea level, and the coast is roughly 0.9 km away, so salt-laden air and a flat, low-lying site shape how a warehouse envelope performs. Before any spray foam goes on, the technician checks the roof and wall surfaces for moisture, dust and loose material, because foam bonds poorly to a damp or dirty substrate. Pricing for spray foam in this area is typically SAR 20–45 per m², and that range reflects how much surface preparation the building needs, so a clear first check keeps the estimate honest.

What is left to the site visit is the detail that cannot be judged from a distance. The technician measures the actual wall and roof areas, confirms whether any cracks need crack injection (SAR 40–120 per metre), and decides whether the roof needs a separate liquid waterproofing layer at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m². Where a warehouse holds stored liquids or has an internal tank, the tank lining (SAR 25–60 per m²) is assessed on site too. Ventilation access, ceiling height, roof pitch and the position of fixtures all affect how the spray is applied, so these are noted in person rather than assumed. Where insulation boards are considered as an alternative, XPS boards (SAR 12–30 per m²) are compared against the foam option at this stage.

To help the technician arrive prepared, it is useful to have the warehouse floor plan or rough dimensions, the total roof and wall area in square metres, and any history of leaks, condensation or cracking. Note which areas are used for storage and whether temperature control is needed, and mention any previous coatings or repairs. Access arrangements, including working hours for an occupied warehouse, should be confirmed in advance. With these details ready, the site visit can move quickly from inspection to a clear, itemised scope of work for the building.

For warehouses, work is phased around operations and stored goods.

Signs that call for spray foam insulation

These are the signs most often linked to spray foam insulation:

• Thermal and water insulation needed together
• Leaks from the panel joints
• A hot metal-sheet roof or hangar

The most common causes

• Joints in metal sheets and sandwich panels.
• A common cause: no UV protection on the surface.

Tools we use in Jubail

How the work is done, step by step

1. Survey: Joints, fixings and gutters are checked.
2. Preparation: The surface is cleaned and dried.
3. Spraying in layers: Foam is applied in passes to the agreed thickness.
4. Protection: A UV-resistant top coat protects the foam.
