Floor & balcony waterproofing in Jubail: the local context

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

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

Do floors and balconies in Jubail really need waterproofing, given how close the town is to the coast? 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 means salt-laden air and damp ground are part of daily life here, and for company premises with heavy foot traffic and equipment, moisture that gets under a floor or balcony slab can quietly spread into the structure before anyone sees a stain. Floor and balcony waterproofing is the layer that stops that water from getting in, and the right system depends on what the surface has to handle.

Our inspection starts with a walk-through of the floor or balcony to note the surface type, any cracks, ponding areas, and signs of water staining on the ceiling below. Where cracks are found, the technician measures their length, since crack injection is priced per metre and is often the first step before a coating goes down. The area is then measured in square metres so the cost can be worked out against the relevant rates: liquid roof waterproofing runs at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², and epoxy coating at SAR 35–90 per m². The inspector will recommend a system that suits the traffic and exposure of the space, and will explain the reasoning before any work begins.

To make the visit efficient, please have the floor plan or a rough sketch of the area ready, including the balcony or floor dimensions if you know them. Note any past leaks, repairs, or areas where water collects after rain, and tell us how the space is used, whether it carries vehicles, machinery, or regular staff traffic. Clear access to the area and to the ceiling below, where leaks are visible, will help the inspector judge the source of any damage. Having these details at hand lets the visit focus on the problem rather than on gathering background, and gives you a clearer quote to compare.

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