Floor & balcony waterproofing in Alnuayriyah: the local context

Team note on Alnuayriyah: 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.. Main roads in or near Alnuayriyah: King Abdulaziz Road.

The centre of Alnuayriyah sits about 49 m above sea level (SRTM open elevation data).

The first thing checked at a floor and balcony waterproofing job in Alnuayriyah is the ground the building sits on, because the centre of Alnuayriyah sits about 49 m above sea level (SRTM open elevation data). That height means the site is not a low-lying hollow where water pools after rain, so the technician looks first at how water drains away from each floor slab and balcony edge rather than assuming it will collect and stand. Falls, outlets and the condition of existing drainage are reviewed before any product is chosen, since a well-drained balcony behaves very differently from one that holds water against its edges.

Several things can only be judged on the site visit and are left there. The technician walks the surfaces to find cracks, hollow patches and places where old coatings have lifted, and decides whether a crack needs injecting, which is priced at SAR 40–120 per metre. The choice between a liquid roof system at SAR 8–25 per m², a bitumen membrane at SAR 15–35 per m², or spray foam at SAR 20–45 per m² depends on the exact surface, its age, its exposure to the sun and whether foot traffic will cross it. Bathrooms and any basement-adjacent areas are assessed separately, with basement work costing SAR 50–150 per m² and bathroom work SAR 15–40 per m², because each needs its own inspection of joints, skirting and wall junctions.

To help the technician prepare, residents and property managers should note the balcony and floor areas as accurately as they can, mention any past leaks or stains, and say whether the surface is used for storage, parking or as a living space. Access to the building roof and balconies should be arranged in advance, and any previous repairs or coatings should be described. This information lets the visit focus on the real conditions, so the quotation reflects the work that is actually needed rather than estimates made from a distance.

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