What is specific about Yanbu for spray foam insulation

Team note on Yanbu: 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.. Main roads in or near Yanbu: King Abdulaziz Road, Umluj Road, Al Hanan Street.

The centre of Yanbu sits about 6 m above sea level (SRTM open elevation data). Yanbu is about 1.2 km from the sea coast (OpenStreetMap).

In Yanbu, the first thing a technician checks is the villa's position relative to the coast. The centre of Yanbu sits about 6 m above sea level, and the town is about 1.2 km from the sea coast, so the site is close enough to the water for salt-laden air to matter while still being on higher ground than the shoreline. Because of this, the crew looks at the external walls and roof edges first, where salt and wind exposure are greatest, and notes how the building is oriented to the prevailing breeze. Spray foam is applied per square metre, typically at SAR 20–45 per m², so the crew measures the exposed surfaces early to give a realistic estimate before any material is ordered.

The site visit is where the rest of the decisions are made. The technician walks the villa to judge whether spray foam is the right choice for each area, or whether another system suits it better. Basements, if present, are assessed separately for waterproofing at SAR 50–150 per m², and wet rooms are noted for bathroom waterproofing at SAR 15–40 per m². Any hairline or structural cracks are recorded, since crack injection is priced per metre at SAR 40–120 per m and must be repaired before foam goes on. Roof condition decides between liquid waterproofing at SAR 8–25 per m² and a bitumen membrane at SAR 15–35 per m². Water tanks, if the villa has them, are inspected for tank internal coating at SAR 25–60 per m², and the owner is asked about any existing insulation boards, since XPS boards at SAR 12–30 per m² may be a better fit for certain walls.

To help the technician prepare, it is useful to have the villa's floor plan and a rough count of the floors, along with photographs of the roof, the exterior walls, and any cracks already noticed. Note which rooms are air-conditioned and which get the most afternoon sun, as this shapes where insulation makes the most difference to comfort. Tell the crew about any past leaks, damp patches, or previous repairs, and whether the roof is accessible for work. Clear access to the areas to be treated, and moving furniture away from walls in advance, saves time on the day. Having this information ready lets the technician give a more accurate quote and a sensible plan for the work.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.

Signs worth paying attention to

The following signs are worth checking before they grow:

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

Causes we see in the field

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

Tools and methods, and when we use them

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.
