Bathroom waterproofing for schools in Sakaka

Why bathroom waterproofing differs in Sakaka

The centre of Sakaka sits about 555 m above sea level (SRTM open elevation data). Team note on Sakaka: 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..

Bathroom waterproofing in schools in Sakaka most often fails at the floor-to-wall junction and around drains, where water that is not properly sealed seeps into the slab and the walls behind the tiles. In a school, washrooms are used constantly by large numbers of pupils, so small leaks can stay hidden for a long time before staining, blistering paint or softening the screed becomes visible. The starting point for a good job is therefore not the tile but the membrane beneath it, with particular attention to corners, pipe penetrations and the edges where the wet area meets the corridor.

Sakaka sits about 555 m above sea level, which means the local climate and the way the ground behaves can differ from coastal cities. Our approach for these washrooms takes that into account by checking the substrate carefully before any coating goes on, filling cracks at the source and choosing a system suited to the surface. Bathroom waterproofing is priced at SAR 15–40 per m², while epoxy coating ranges from SAR 35–90 per m² and spray foam from SAR 20–45 per m², so the right system depends on the condition of the floor, the amount of traffic and how much wet use the room receives each day. Where a wall shows a crack, crack injection at SAR 40–120 per metre may be needed before the main coating is applied.

Before the visit, it helps to have a few details ready. Tell us the number of washrooms, whether the floors are tiled or bare screed, and whether you have noticed damp patches, staining or peeling paint on the walls below. Let us know if any washroom sits above a store room, a classroom or a basement, since that changes the level of protection needed. Please also mention any recent repairs to pipework, because a fresh joint can be the cause of a leak that appears later. With these details, we can plan a visit that looks at the problem areas first and gives you a clear picture of the work before anything starts.

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

Signs worth paying attention to

If you notice one of these signs in Sakaka, it is a good moment to talk to the team:

• Worn grout
• A stain under the bathroom on the floor below
• Damp around the shower

Causes we see in the field

• The area around the floor drain — we check this before anything else.
• Corners without waterproofing tape — we check this before anything else.
• A damaged floor layer — we check this before anything else.
