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..

Bathroom waterproofing work in Qatif begins with the site's location, because the town's position shapes what a technician looks for first. 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). A technician therefore checks how water moves across and beneath the floor, and whether moisture from the ground or from nearby damp conditions could reach the bathroom base. This is why the first inspection focuses on the drainage slope, the floor-to-wall junction, and any signs of old water staining, rather than on surface finish alone.

Several things are left to the site visit, since they cannot be judged from a description or a map. The technician needs to see the existing tiles, the condition of the grout, the state of the drain and its outlet, and whether the wall plaster is sound or already breaking down. Cracks that are wider than a hairline, or that run through the screed, are assessed on the spot, because crack injection is priced by the metre (SAR 40–120 per m) and the length can only be measured once the crack is traced. The choice of system also depends on the room itself. Bathroom waterproofing is priced at SAR 15–40 per m², epoxy coating at SAR 35–90 per m², and spray foam at SAR 20–45 per m², so the technician weighs the surface, the wear it will take, and the budget you have set before recommending one method.

To help the technician, have the following ready when the visit is booked. Tell us the approximate floor area of the bathroom and whether the room sits above another living space, since that changes how the work is scoped. Mention any previous leaks, repairs or repainting, and any water stains on the ceiling below. If the bathroom shares a wall with a shower, a washing area or a lift shaft, say so. Clear access to the drain and the walls, and a note of when the room is least used, will let the technician work efficiently and give you a clearer written quote.
