A school in Yanbu is a busy place, with many students, staff and daily cleaning, and a bathroom that is used all day puts constant strain on floors and walls. Picture a school owner who has noticed damp patches near the wash basins and a smell in the corridor after rain. They want the washrooms dry, safe and clean for pupils without closing the building for weeks, and they need to know what the work will involve before they agree to anything.
The local facts matter here. The centre of Yanbu sits about 6 m above sea level, and the town is about 1.2 km from the sea coast. That mix of low elevation and nearby coast means moisture and salty air are part of everyday conditions, so a bathroom floor and wall system needs to be sealed well rather than just patched. For a school, a bathroom that stays damp can lead to mould and tile lifting, so choosing a suitable waterproofing approach early saves repeat work later. Bathroom waterproofing for this type of room is typically priced at SAR 15–40 per m², and epoxy coating at SAR 35–90 per m², which gives the owner a clear range to compare when reviewing quotes.
A sensible sequence starts with a site check. Ask the contractor to look at floor falls, drains, cracks and any old tiles that are loose or hollow. Where there are cracks, crack injection (SAR 40–120 per metre) can be done before the main coating. Next, prepare the surfaces so the new layer will bond, then apply the chosen system in the number of coats recommended for the material. Let each coat cure fully before the next, and test the finished floor with water before tiling or returning the room to use. Finally, agree on a simple maintenance routine with the school staff so that drains stay clear and any new hairline cracks are reported early.
For schools, the larger jobs are planned for weekends and holidays.
