Why bathroom waterproofing differs in Makkah
The centre of Makkah sits about 301 m above sea level (SRTM open elevation data). Team note on Makkah: 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 school buildings in Makkah most often starts with failures that show up as damp patches on the wall below wet areas, peeling paint, and tile joints that stay dark after cleaning. In schools, these areas are used heavily through the day, and small leaks can spread into corridors and classroom walls before anyone notices. The usual cause is a membrane that was never properly bonded at floor-to-wall junctions, or a drain area that holds water because the slope is wrong. Treating the surface alone rarely solves it, so the first step is to find where the water is getting in.
Local conditions shape the approach. The centre of Makkah sits about 301 m above sea level (SRTM open elevation data), so the area is not low-lying, but heavy rain runoff from surrounding slopes can still push water toward older buildings and their ground-level bathrooms. For bathroom work, the typical range is SAR 15–40 per m², and the method depends on the surface. Epoxy coating is priced at SAR 35–95 per m² and suits smooth, sealed floors that must be cleaned often. Spray foam at SAR 20–45 per m² can be useful on awkward shapes. Where a cracked wall or floor joint is the source, crack injection is charged at SAR 40–125 per metre, which means the crack must be located before the job is scoped. A survey that maps wet areas and cracks will therefore affect the final price more than the size of the room.
Before the visit, ask the provider to confirm which surfaces they will test and how they will check for leaks, and whether the quote is per m² or per metre for cracks. Ask what preparation the school must do, such as clearing storage, arranging access outside class hours, and keeping water off the area during curing. Ask how long the works will take in days, and whether the bathroom can be returned to use in a set timeframe. Finally, ask what the warranty covers and who handles follow-up if a leak returns. Clear answers to these points make it easier to compare offers and to plan around the school timetable.
For schools, the larger jobs are planned for weekends and holidays.

Questions from Makkah
What does finishing work typically include?
It covers plastering, painting, flooring, stone or marble walls, ceilings, gypsum, doors, windows, and final electrical and plumbing installations. You can request full or partial finishing, with the scope clearly defined in the price quote.
Is it possible to renovate the building without evacuating the residents?
In many cases it can be carried out in phases without a full evacuation if the damage is limited. However, for extensive structural renovation, a temporary evacuation may be recommended to ensure safety, and the contractor will explain this in their proposal.
Does waterproofing require removing existing tiles?
It depends on the site condition. Sometimes surface waterproofing can be applied over tiles, while deep leaks require tile removal to treat the layer underneath. A technician will determine the best option after inspection.
