Before we start: what we know about Abu Arish

The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data). Team note on Abu Arish: 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..

An owner of a family villa in Abu Arish usually notices the problem first in the evenings: a cool draught along the wall of a ground-floor room, or a patch of damp near the window frame after a rainy spell. Many of these homes were built with thin walls and roofs that were not designed for the heat of the day and the chill of the night, so the rooms feel uneven and the air conditioning runs longer than it should. For this type of property, spray foam insulation is often considered as a way to close gaps in the building envelope and reduce heat transfer through walls and roofs, without tearing out finished interiors.

The local facts shape how an owner should think about this. Abu Arish sits about 67 m above sea level, which places it on higher ground than the coastal plain, so the terrain drains differently and rainwater can run across sloped plots toward the foundations. That makes the link between insulation and moisture control important: spray foam performs best when the surfaces beneath it are dry and sound, and when the basement and bathroom areas are already protected. Owners should also compare costs across the options. Spray foam is quoted at SAR 20–45 per m², which sits between XPS boards at SAR 12–30 per m² and epoxy coating at SAR 35–90 per m². Where cracks are visible, crack injection at SAR 40–120 per metre may need to come first, and liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² can protect the roof before any foam is added.

A sensible sequence starts with a walk-through of the property to note damp patches, hairline cracks and areas where the roof ponds water after rain. Next, repair any cracks and address basement or bathroom waterproofing, since these are the places where moisture enters most easily. Then confirm that the roof has its own waterproof layer, and only after the surfaces are dry and sealed should the owner arrange the spray foam work on the exposed walls or roof sections. Finally, ask the applicator to record the area covered in square metres so the final cost can be checked against the rates above, and schedule a follow-up inspection after the first wet season to confirm the result.

For a residential building, shared risers, tanks and pumps are checked as one system.

Signs that call for spray foam insulation

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

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

Where the problem usually comes from

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