Bathroom waterproofing for schools in Taif

Before we start: what we know about Taif

The centre of Taif sits about 1673 m above sea level (SRTM open elevation data). Team note on Taif: 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..

Picture the manager of a private school in Taif, responsible for a building with several washrooms used by hundreds of pupils every day. Wet floors, slow drains and damp patches on the corridor wall are routine complaints, and the bathrooms are often the first place where small leaks turn into expensive repairs. The owner usually has to balance daily use with limited closure windows, so any waterproofing work must be planned carefully rather than rushed.

Taif sits at around 1673 metres above sea level, which matters for building upkeep. Higher ground in this region can mean a noticeable difference in temperature between day and night, and that movement can open hairline cracks in wall joints and floor screeds. Because bathroom areas are exposed to constant water, those cracks become entry points. For a school, the practical meaning is clear: inspect the bathroom walls and floors regularly, look for cracks before they grow, and treat waterproofing as part of routine maintenance rather than an emergency measure. Bathroom waterproofing is typically priced at SAR 15–40 per m², while crack injection is SAR 40–115 per metre, so catching a crack early is usually the more economical choice.

A sensible sequence starts with a survey of every washroom, noting cracks, damp patches and areas where tiles sound hollow. Next, cracks should be repaired by injection before any coating is applied, since a coating over an open crack will not hold. Then choose the system that suits each surface: epoxy coating (SAR 35–85 per m²) for high-wear floors, or a bitumen membrane (SAR 15–35 per m²) where a flexible sheet is needed. Schedule the work during holidays so classrooms stay open, allow each layer to cure fully before the area returns to use, and finish with a documented inspection so the school has a record for future maintenance.

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

Tools and methods, and when we use them

From the first visit to the report

1. Finding the source: A supply-pipe leak is ruled out first.
2. Preparation: The floor is opened and cleaned where needed.
3. Corners and details: Tape and detailing at corners, drains and pipe entries.
4. Flood test: The floor is tested before tiling.
