What is specific about Qatif for spray foam insulation

Qatif is about 2.5 km from the sea coast (OpenStreetMap). The centre of Qatif sits about 5 m above sea level (SRTM open elevation data).

Team note on Qatif: 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..

Qatif sits only about 5 m above sea level, and the coast lies roughly 2.5 km away, so a technician's first check for a warehouse is how moist air and salt-laden conditions may reach the building envelope. Before any foam is sprayed, the crew looks at the roof deck, the wall base and any ground-level slab for signs of damp, staining or old sealant failure, because a warehouse with trapped moisture will not hold spray foam well. The rate for spray foam here is SAR 20–45 per m², and the quote is set only after the surface condition is clear, since poor substrates can add preparation work. Where the building sits close to the shoreline, the crew also notes whether drainage carries water toward the walls, as that affects which parts of the envelope need attention first.

Several things can only be settled at the site visit. The exact thickness of foam needed depends on the roof profile, the height of the walls and how the space is used, and the team measures these in person rather than estimating from a plan. The condition of any existing crack injection or old liquid roof waterproofing, which runs at SAR 8–25 per m² on a fresh job, is judged by hand and eye. Access for equipment, ventilation during spraying and whether stock or racking must be moved are also confirmed on the day, along with any neighbouring units that may be affected by overspray or fumes.

To help the technician, it is useful to have the warehouse floor area, the roof area and the height of the walls ready, along with any drawings or past repair records. Tell the team whether there have been leaks, where water has been seen and at what time of year, and whether the building has been used for cold storage, since this changes the approach. If a bitumen membrane (SAR 15–35 per m²), XPS boards (SAR 12–30 per m²) or an epoxy coating (SAR 35–90 per m²) was applied earlier, note it so the crew can check compatibility. Clear access to the roof and the wall base makes the visit faster and gives a more accurate picture of the work needed.

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

Signs worth paying attention to

If you notice one of these signs in Qatif, it is a good moment to talk to the team:

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

Where the problem usually comes from

• A common cause: joints in metal sheets and sandwich panels.
• No UV protection on the surface — we check this before anything else.

Tools and methods, and when we use them

From the first visit to the report

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.
