A school bathroom in Dhahran sees heavy daily use, with many students and staff using the same wet areas through long terms. Its owner or facilities manager is usually responsible for keeping floors, wall bases and drains dry and sound, while avoiding repeated closures that disrupt lessons. Water that escapes a worn floor can soak into surrounding walls and ceilings, so problems that start small can spread into classrooms below or beside the washrooms.
The local facts matter here. The centre of Dhahran sits about 16 m above sea level, and the town is about 5.9 km from the sea coast. Because the site is not at the water's edge, owners should not assume damp is caused only by salt air or groundwater. Instead, they should look first at the condition of the bathroom itself: tile joints, floor falls towards drains, and the junctions where walls meet floors. For bathroom waterproofing, the indicative cost range is SAR 15–40 per m², which helps a school budget the work by floor area. Where cracks appear in the structure, crack injection is priced at SAR 40–120 per metre, so measuring cracks early keeps the scope clear.
A practical sequence starts with a survey. First, mark every area where water pools, stains appear, or tiles have loosened, and record the length of any cracks. Second, check that floors slope gently towards drains and that drains are clear, because standing water is the most common cause of premature wear. Third, repair cracks and damaged joints before any coating goes on. Fourth, choose a waterproofing system suited to the wet zone, such as an epoxy coating at SAR 35–90 per m² for high-wear floors or a liquid membrane for lighter areas. Fifth, allow the material to cure fully before tiling or reopening the room, and schedule the work during holidays so classes are not interrupted.
For schools, the larger jobs are planned for weekends and holidays.
