Before we start: what we know about Alqunfudhah

Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap). The centre of Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).

Team note on Alqunfudhah: 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..

Spray foam insulation in a restaurant is usually asked for to solve heat and noise, yet the most common problem in this setting is moisture and heat leaking through kitchen walls and roof slabs, which makes cooling bills climb and surfaces sweat near cooking lines. For restaurants, the work has to fit around grease-laden air, hot equipment and tight service hours, so the foam must bond cleanly to the substrate and be sealed properly at every penetration for ducts and pipes.

In Alqunfudhah, the centre sits about 7 m above sea level, and the town is about 0.4 km from the sea coast. Those two facts matter. Being so close to the coast means salt-laden humid air reaches the building, which can get into gaps and keep surfaces damp, so the installer should check for moisture before spraying and treat any damp patch first. The low elevation also means that after heavy rain water can pool around the building, so the surfaces that meet the ground, such as the lower walls and any basement or storage room, need attention. Where that risk is present, basement waterproofing at SAR 50–150 per m² or crack injection at SAR 40–120 per metre may need to be considered alongside the foam, and an installer should say so openly rather than only quoting for insulation. Roof work can likewise be priced with liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² if the roof is the main source of trouble.

Before the visit, ask the provider which areas they plan to cover, whether they will check for moisture and cracks first, and how they will protect food-contact zones and extraction equipment during spraying. Ask for the rate per m² for spray foam, which starts at SAR 20–45 per m², and ask how any extra waterproofing work would be quoted. Also ask how long the restaurant will need to stay closed or partly closed, and whether the work can be done outside service hours. A clear answer to these points will show whether the provider understands both the building and the coastal conditions around Alqunfudhah.

For restaurants, visits are planned outside service hours and recorded for the premises file.

Signs that call for spray foam insulation

The following signs are worth checking before they grow:

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

The most common causes

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

Tools we use in Alqunfudhah

The steps in order

1. Survey: Joints, fixings and gutters are checked.
