Why bathroom waterproofing differs in Jazan

Team note on Jazan: 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 Jazan sits about 7 m above sea level (SRTM open elevation data).

Jazan is about 1.9 km from the sea coast (OpenStreetMap).

Is a bathroom in a hotel or serviced apartment in Jazan really at risk of water damage? The city centre sits about 7 m above sea level, and Jazan is about 1.9 km from the sea coast. That means the ground is low-lying and close to moist coastal air, so water that gets behind tiles or into a floor slab can linger and spread. Bathroom waterproofing is typically priced at SAR 15–40 per m², and for wet areas that serve guests every day, keeping the seal intact is far cheaper than repairing damp walls, stained ceilings and corroded fittings after the fact.

Our inspection starts with a walk through each bathroom to look for the early signs of trouble: hairline cracks in the screed, lifted or hollow-sounding tiles, grout that has darkened or crumbled, and soft or discoloured paint near the shower and floor edges. Where a crack is found, crack injection is priced at SAR 40–120 per metre, and we note its length so the cost can be set out clearly before any work begins. We also check the junctions between floor and wall, around the drain and where pipes pass through, because these are the points where water most often finds its way through. Where a membrane or coating is already in place, we test whether it is still bonded and continuous rather than assuming it is sound.

To make the visit efficient, please prepare the following before we arrive. Clear the bathroom floors and move any loose furniture or fittings away from the walls so the surfaces can be checked properly. Let us know which rooms are in use and when guests are least likely to be disturbed, so we can plan around occupancy. Gather any earlier waterproofing records, warranty papers or invoices for past repairs, as these show what was installed previously. Finally, note any rooms where you have already seen staining, bubbling paint or a musty smell, so we can give them priority. With this information ready, the inspection can focus on the areas that matter most.

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