Bathroom waterproofing in Buraydah: the local context

The centre of Buraydah sits about 606 m above sea level (SRTM open elevation data). Team note on Buraydah: 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 Buraydah sits about 606 m above sea level (SRTM open elevation data), and that elevation shapes how we approach bathroom waterproofing for schools in the city. Before anything else, the technician checks how water will move across and away from the wet areas, since school bathrooms are used heavily and drainage falls need to be correct for the floor to stay dry. Bathroom waterproofing is priced at SAR 15–40 per m², and the first question is which system suits the substrate, so the team compares options such as liquid roof waterproofing at SAR 10–25 per m², epoxy coating at SAR 35–85 per m², and spray foam at SAR 20–45 per m². Crack injection, priced at SAR 40–115 per m, is considered early wherever hairline cracks appear near floor-to-wall junctions.

Several things cannot be settled from a description and are left to the site visit. The technician needs to see the existing floor build-up, the condition of the tiles and grout, the height of the upstand at the walls, and where the floor drains sit relative to the slope. Access to the space is also assessed on the day, because schools operate on fixed timetables and the work may need to be sequenced around classes. If the bathroom sits above another occupied room, the team will check that as well, and will confirm whether any insulation layer such as XPS boards at SAR 10–30 per m² is needed. Where a water tank is nearby, the internal coating option at SAR 25–55 per m² may come into the discussion, but only once the site has been inspected.

To help the technician prepare, it is useful to have the building plans, the age of the bathroom fit-out, and any notes on past leaks or repairs to hand. Information about when the bathrooms are least busy will also help plan the work with the school. Photographs of problem areas, taken in good light, let the team judge the extent of damage before arriving. Noting whether previous repairs used bitumen membrane, priced at SAR 15–35 per m², gives the technician useful context about what is already beneath the surface. Clear answers on these points make the site visit shorter and the recommendation more precise.

For schools, the larger jobs are planned for weekends and holidays.
