Bathroom 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).

Qatif's centre sits about 5 m above sea level, and the town lies roughly 2.5 km from the coast. Those two facts shape where we look first: in a home this close to the shore, moisture reaching the bathroom floor and walls can come from the ground below as well as from the water inside the room. So the first checks are the floor-to-wall junction, the drain outlet, and any hairline cracks near the shower tray, because these are the places where water most often finds a way through. We also look at whether the existing surface is sound enough to bond to, since a coating laid over dust, old sealant or loose tiles will fail early regardless of the material used.

Some things cannot be judged from a message or a photograph, so they are left to the site visit. The technician will walk the room, press on the tiles to listen for hollow spots, check the slope toward the floor drain, and assess whether the damp is coming from the bathroom itself, from a neighbouring wall, or from beneath the slab. Costs also depend on the chosen system. Bathroom waterproofing is typically priced in the range of SAR 15–40 per m², epoxy coating SAR 35–90 per m², and spray foam SAR 20–45 per m², but the final figure depends on the measured area and condition of the surface. Crack injection is charged per metre at SAR 40–120 per m, so the number of cracks found on site changes the total considerably.

To help the technician arrive prepared, note the age of the bathroom, any tiles that have lifted or sound hollow, where you have noticed staining or a smell, and whether the damp appears after showers, after rain, or all the time. Photographs of the walls and floor, taken in daylight, are useful. Please also mention whether the room sits above another home, a store or a garage, because that affects access and the choice of method. Clear answers to these questions let the visit focus on the real problem rather than on guesswork.

The aim is to locate the cause with instruments first, so any opening is limited to one point.
