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

The centre of Qatif sits about 5 m above sea level (SRTM open elevation data).

Floor and balcony waterproofing work for hotels and serviced apartments in Qatif begins with the location itself. The centre of Qatif sits about 5 m above sea level (SRTM open elevation data), and the town is about 2.5 km from the sea coast (OpenStreetMap). Because the ground is low and close to the coast, technicians check first how water moves across and under the floor slabs, and whether drainage outlets, slopes and balcony edges are working as they should. Standing water on balconies, staining on ceilings below and damp patches near floor drains are noted before any materials are chosen.

Some matters can only be settled on site. The technician will inspect the existing surface condition, look for cracks and their direction, test whether the substrate is sound, and measure the true area to be treated. The choice between a liquid membrane, a bitumen layer, spray foam or an epoxy finish depends on what the surface can take and how the building is used, so this decision is made during the visit rather than from a desk. Access arrangements, the number of occupied rooms, and the hours when balconies can be closed off for work are also agreed on site, as they affect how the job is sequenced in an active hotel or apartment building.

To help the technician prepare, the property team should provide the number of floors and the approximate balcony and floor areas, along with any previous waterproofing records and warranty papers. Note which rooms or balconies leak, when the problem appears (after rain, after showers or all the time), and whether any cracks have been injected before. Indicative rates are published for reference: liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², epoxy coating at SAR 35–90 per m², and crack injection at SAR 40–120 per m. Final figures are confirmed only after the site inspection.

For hotels and serviced apartments, rooms are handled in batches to keep units available.
