Floor & balcony waterproofing in Yanbu: the local context

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

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

Floor and balcony waterproofing for warehouses in Yanbu begins with the location itself. The centre of Yanbu sits about 6 m above sea level, and the town is about 1.2 km from the sea coast. Both facts matter for a warehouse floor. Sitting close to the coast means salt-laden air and moisture can reach concrete slabs and joints, so the technician should look first at the condition of the floor surface, the edges where the slab meets walls, and any drainage points that might hold water. Because the ground is only a few metres above sea level, the team also checks whether water is likely to pool rather than run off, since standing water tests a coating far more harshly than dry use.

Other points are left to the site visit, because they depend on what is physically in front of the technician. The team walks the full floor area to note hairline cracks, movement joints, blistering, old coatings that have peeled, and any patches of damp. They measure the real area in square metres, since the cost of most systems is quoted per square metre, and they record the length of any cracks that need injection, because that work is priced per metre. The site visit also confirms how the floor is used: forklift traffic, heavy racking, spilled chemicals, and whether the warehouse has any balcony or raised platform that needs separate treatment. The choice between a membrane, an epoxy coating, a spray foam, or a liquid system depends on these observations rather than on any single rule.

Information that helps the technician prepare is simple to gather in advance. It helps to know the approximate floor area, the age of the slab, any previous repair records, and whether the floor has been wet recently. Pricing ranges are useful for planning: epoxy coating runs from SAR 35 to SAR 90 per m², spray foam from SAR 20 to SAR 45 per m², and a bitumen membrane from SAR 15 to SAR 35 per m². Crack injection is priced at SAR 40 to SAR 120 per metre. Clear access to the floor, a dry spell for application, and a list of any stored goods to be moved will all help the work proceed without delay.

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