Bathroom waterproofing in Tabuk: the local context

Team note on Tabuk: 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 Tabuk sits about 762 m above sea level (SRTM open elevation data).

Bathroom waterproofing for schools in Tabuk starts with the building's position on the land. The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data), so the first check at any school is the general condition of the bathroom floors and walls, together with how water already drains away from them. Because the city is high and the climate is dry, technicians look closely at surface cracks and old coatings that may have lifted, since these are the usual routes for water to reach the structure below. Bathroom waterproofing is priced at SAR 15–40 per m², and the scope is set after this first look rather than before it.

Several points cannot be settled from a description alone and are left to the site visit. The technician must see whether cracks are active, whether a coating has failed beneath the tiles, and how far the damage runs into adjacent corridors or store rooms. Where cracks are found, crack injection is priced at SAR 40–115 per metre, and the choice between that and a full surface system depends on what is seen on the day. Epoxy coating, priced at SAR 35–85 per m², and spray foam, priced at SAR 25–35 per m², are both possible, and the right option is decided on site. The same applies to any roof or tank areas on the school grounds, where liquid roof waterproofing at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², and tank internal coating at SAR 25–55 per m² are all considered only if the survey shows they are needed.

Information that helps the technician is worth gathering before the visit. Note the age of the building, any earlier repairs, and whether the bathrooms sit above occupied rooms or a basement, since basement waterproofing is priced separately at SAR 50–145 per m² and XPS boards at SAR 10–30 per m² are sometimes used as a protective layer. Record the areas in square metres and any locations where water has been seen. Clear access to the bathrooms during school hours, and a named contact for the site, will let the work be planned around lessons and keep disruption to pupils to a minimum.

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