What is specific about Jubail for bathroom waterproofing

Team note on Jubail: 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 Jubail sits about 4 m above sea level (SRTM open elevation data).

Jubail is about 0.9 km from the sea coast (OpenStreetMap).

Jubail sits low and close to the coast. The centre of Jubail is about 4 m above sea level, and the town is about 0.9 km from the sea coast. Because of this, the first thing a technician checks in a bathroom here is how water moves toward the floor drain and whether the slab falls to it. Damp air and salt-laden moisture from the coast can work into tile joints and render, so the technician looks for signs of rising damp at the base of walls and for any staining that suggests water is already getting under the finish. Pricing for bathroom waterproofing in this area is published at SAR 15–40 per m², which gives a starting point, but the final area and method depend on what the visit reveals.

Several things are only settled on site. The technician needs to see the existing tiling, the condition of the screed, and whether the bathroom sits over another room or a shared slab, since that changes how far the membrane must run up the walls. The fall to the drain, the position of the shower tray, and any cracks in the floor or the junction between floor and wall are all checked by eye and by touch. Whether a crack needs injecting, at SAR 40–120 per metre, or simply needs sealing before the main coating is decided only after the cracks are measured. The choice between a liquid membrane, an epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², or a bitumen membrane at SAR 15–35 per m² also depends on how the surface behaves when it is tested.

Information that helps the technician is worth gathering before the visit. Note the bathroom's approximate dimensions, the number of wall sections to be covered, the age of the building, and any past leaks or repairs. Photos of visible cracks, stains and the drain area speed up the assessment. Tell the team if the room is used heavily or if water pools on the floor, because that affects which coating will hold. A clear account of where damp has appeared, and when, lets the technician plan the work without guessing.
