Before we start: what we know about Jubail

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

Jubail is about 0.9 km from the sea coast (OpenStreetMap).

Will spray foam insulation hold up for a company building in Jubail, a town that sits close to the Gulf coast? The short answer is that Jubail's position makes insulation and moisture control a real concern. The centre of Jubail sits about 4 m above sea level, and the town is about 0.9 km from the sea coast. That closeness to the water means humid air and salt-laden breezes are part of daily conditions, so a building envelope has to be sealed well and checked regularly. For companies that run several buildings or sites, spray foam work is usually priced per square metre, with a typical range of SAR 20–45 per m², and it can be arranged under an annual contract so that inspections and minor repairs are handled on a set schedule.

The inspection steps begin with a walk through the building to look for signs that insulation or waterproofing is failing. The crew checks roofs, external walls, and any areas where water may collect or travel. Where cracks are found, they are measured and recorded, since crack injection is priced per metre at SAR 40–120 per m. Roof surfaces are assessed for liquid roof waterproofing needs, priced at SAR 8–25 per m², and bitumen membrane condition is noted where it applies, at SAR 15–35 per m². Basements and below-ground areas are reviewed separately, because basement waterproofing ranges from SAR 50–150 per m². Each finding is written up so the company can decide what to schedule first and what can wait for the next visit under the contract.

Before the inspection visit, a company should prepare a few simple things. Gather the building plans or drawings, a list of all sites covered by the contract, and any records of past repairs or leaks. Clear access to roofs, plant rooms, and basement areas so the crew can work without delay. Note any areas where staff have reported damp patches, cracks, or odours, and mark them on a plan if possible. Confirm who will receive the report and who will approve any work, so that quotes can be issued and agreed promptly. Good preparation makes the visit shorter and gives the team a clear picture of what the site needs.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
