Floor & balcony waterproofing in Qatif: the local context

Team note on Qatif: 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 Qatif sits about 5 m above sea level (SRTM open elevation data).

Qatif is about 2.5 km from the sea coast (OpenStreetMap).

Before any material is chosen for a restaurant floor or balcony in Qatif, the technician first looks at how close the building sits to the coast, because that shapes how salt and moisture reach the slab. The centre of Qatif sits about 5 m above sea level, and the town is about 2.5 km from the sea coast. Those two facts mean that salt-laden air and groundwater are real concerns here, so the first checks focus on whether the surface shows salt bloom, efflorescence, or patches that stay damp after cleaning. Kitchen drains, grease traps and wash-down areas are also inspected early, since restaurant floors take heavy water use every day and any leak into the slab below can be costly to fix later.

Several things are left to the site visit itself, because they cannot be judged from a distance. The technician will walk the floor and balcony, mark any cracks, and measure the areas that need coverage so that a proper quotation can be prepared. Slope toward drains, the condition of old coatings, and whether the balcony edge has upstands or sealed joints are all recorded on the spot. Access for work during opening hours is also agreed at this stage, since a working kitchen cannot simply close for days. Pricing is then compared across the options that suit the findings, for example epoxy coating from SAR 35–90 per m², spray foam from SAR 20–45 per m², or crack injection from SAR 40–120 per metre, with the final figure set only after the visit.

To help the technician arrive prepared, the restaurant owner can share a few details in advance. Useful information includes the floor area in square metres, the length of visible cracks, the age of the building, any past repairs, and whether the balcony is used for seating or storage. Photos of the drains and of any water stains on the ceiling below are also helpful. Access times, the name of the person who can approve work, and any landlord rules about changes to the balcony should be noted too. With these details ready, the visit moves faster and the quotation reflects the real condition of the Qatif site.

For restaurants, visits are planned outside service hours and recorded for the premises file.
