Before we start: what we know about Baish
Team note on Baish: 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 Baish sits about 84 m above sea level (SRTM open elevation data).
Bathroom waterproofing in school buildings most often fails at the floor-to-wall junction and around floor drains, where water seeps behind tiles and into the slab over time. Staff and students use these washrooms heavily and often, so small leaks can go unnoticed until ceilings below stain or tiles start to lift. In Baish, the centre of town sits about 84 m above sea level, so the site is not low-lying, and the work should focus on the wet zones of the washroom rather than on water rising from the ground.
Local conditions shape the approach. Because Baish is not a low-lying area, we do not treat ground-level water as the main risk for school washrooms. Instead, the priority is sealing the floor and the lower wall areas where daily cleaning and frequent use put water into contact with the structure. Pricing for bathroom waterproofing typically falls in the range of SAR 15–40 per m², while epoxy coating ranges from SAR 35–90 per m² and spray foam from SAR 20–45 per m². The right material depends on the condition of the surface, the amount of cracking, and how much time the washroom can be out of use, so each school needs its own assessment rather than a standard package.
Before the visit, ask the school or facilities team to confirm which washrooms are in use, which ones have had leaks or staining, and whether any cracks are visible in the floor or where the wall meets it. Note the access times, since work in a school usually has to fit around lessons and cleaning schedules. It also helps to have any previous repair records or floor plans ready. If cracks are present, ask whether crack injection is needed, which is quoted at SAR 40–120 per metre. A clear list of these points lets the surveyor scope the job accurately and gives the school a realistic idea of cost before any work begins.
For schools, the larger jobs are planned for weekends and holidays.
