Floor and balcony waterproofing in schools most often fails at drainage points, floor-to-wall joints and cracks at balcony edges, where water sits after rain and slowly penetrates into the slab below. In a school, this shows up as stains on ceilings of classrooms beneath, peeling paint in corridors and damp smells that worsen during the rainy season. Because the damage is usually hidden until it spreads, the first step is a careful inspection of every balcony edge, floor junction and outlet rather than a single coat applied over the surface.

Tarout is a coastal town, and two local facts shape the approach. The centre of Tarout sits about 3 m above sea level, which means drainage can be slow and standing water tends to linger in low corners of flat roofs and balconies. Tarout is about 0.9 km from the sea coast, so salt-laden air is a regular factor in how surfaces age. For these reasons, the work usually starts with clearing and checking outlets and slopes, then choosing a system that tolerates both moisture and salt exposure. Costs vary by method: liquid roof waterproofing is typically SAR 8–25 per m², bitumen membrane SAR 15–35 per m², epoxy coating SAR 35–90 per m², and crack injection SAR 40–120 per metre. A survey should show which of these fits the balcony and floor condition before any figure is agreed.

Before the visit, ask the provider which method they propose for your specific floors and balconies and why it suits a coastal site. Ask how they will treat cracks and drainage points, and whether the quote is per m² or per metre for each element. Request a written description of the surface preparation, the number of coats, and the expected protection for school use, where foot traffic is heavy. Also confirm who will manage the work around class timetables, and ask for photographs of similar past jobs in the area. A clear answer to each of these points tells you whether the provider understands both the building and the Tarout setting.

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