Bathroom waterproofing work in Qatif starts with the location itself. The centre of Qatif sits about 5 m above sea level, according to SRTM open elevation data, and the town is about 2.5 km from the sea coast, based on OpenStreetMap. Because the ground is low and close to the coast, the technician first looks at how water moves in and around the bathroom floor and walls, and whether moisture is already present behind tiles or along the junction with the external wall. These two facts shape the first checks, so that the chosen system suits the damp conditions the building is likely to face.
Several things are left to the site visit, because they cannot be judged from a distance. The technician will confirm the actual condition of the screed, the state of the drainage outlet, the slope toward the drain, and whether old membranes or sealants are still in place. They will also look for cracks at wall and floor junctions, signs of past leaks in the flat below, and the age and type of existing tiles. The chosen method and its cost depend on these observations. Typical rates in the range of SAR 15–40 per m² for bathroom waterproofing are a starting point only, and the final figure is set after the inspection, not before it.
To help the technician, it is useful to have a few details ready before the visit. Note which rooms in the flat are affected, when damp was first noticed, and whether it appears after showers, after rain or all the time. Tell the technician if the flat has a rooftop or upper-floor bathroom above yours, since shared structure can change the approach. If you have photos of stains or cracks, send them in advance. Clear access to the bathroom and the ability to remove a few tiles for inspection will also speed up the assessment and keep the quotation accurate.
In apartment buildings, the floor below is often where a leak shows first.
