Picture the operator of a private school in Riyadh whose term has just started when a stain appears on the ceiling of a classroom below an upper-floor balcony. The administrator is busy, the children are moving between rooms, and nobody wants a leak to interrupt lessons. For an owner of a school building, floor and balcony waterproofing is rarely urgent until water finds a route through, and by then the repair is more disruptive than the prevention would have been.
Riyadh's setting shapes how this work should be planned. The centre of the city sits about 637 m above sea level, and that is the basis for the local conditions owners face. Rain, when it falls, tends to arrive in short, heavy bursts that pool on flat balconies and play areas, and the warm, dry periods between storms stress surfaces through repeated expansion and contraction. For a school, where balconies double as corridors and outdoor spaces, standing water and cracked screeds are a daily safety and maintenance concern, not just a cosmetic one.
A practical sequence starts with a walk-through during a quiet period, noting staining, hairline cracks, ponding and any drains that are blocked. Cracks should be addressed first, since crack injection is priced per metre, from SAR 40 to SAR 125 per m, and is usually a targeted fix. Next, the owner should decide on the surface system: liquid roof waterproofing, from SAR 10 to SAR 25 per m², suits many flat balconies, while bitumen membrane, from SAR 15 to SAR 35 per m², is a common choice where a thicker layer is needed. Epoxy coating, from SAR 35 to SAR 95 per m², can be considered for high-traffic walkways. Finally, schedule the work for holidays so classrooms stay usable, and keep the drains clear afterwards so the new surface can do its job.
For schools, the larger jobs are planned for weekends and holidays.

Common questions about floor & balcony waterproofing in Riyadh
What is the drying time for the floor before use?
The drying time varies depending on the system type, layer thickness, and site temperature. The installer will specify it within the scope of work.
Does detecting bathroom leaks require breaking tiles?
Usually not. Modern tools such as thermal cameras, electronic listening devices, and pressure testing pinpoint the source of a leak with high accuracy. If breaking is necessary, it is limited to the repair point only, after the location has been confirmed.
