Floor & balcony waterproofing for schools in Madinah
In short: In Madinah (Madinah), floor & balcony waterproofing for schools begins with the roof, falls and drains survey and the moisture meter for ceilings and walls; nothing is opened until the position is clear. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Published price: Bathroom waterproofing (per m²), SAR 15–40 per m²; anything else is quoted after the inspection.
Before we start: what we know about Madinah
Team note on Madinah: 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.. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data).
Madinah's city centre sits about 589 m above sea level, which places it on a high plateau rather than on the coast. For floor and balcony waterproofing in schools, that elevation matters because the area sees large temperature swings between day and night, and the hot dry climate can dry and shrink surface layers quickly. We plan the work around these conditions: we check that the substrate has cured and is dry before any membrane goes down, and we schedule application for cooler parts of the day so the coating sets evenly and does not blister.
Each part of a school's floor and balcony system calls for a different approach, and our quotations reflect that. Epoxy coating typically runs SAR 35–90 per m² and suits classroom floors and wet corridors where a hard, easy-to-clean surface is needed. Spray foam at SAR 20–45 per m² and liquid roof waterproofing at SAR 10–25 per m² are commonly used on open balconies and flat roof sections above classrooms. Where a balcony shows movement, crack injection at SAR 40–120 per metre seals the line before any surface work begins, so the new layer is not undone by a crack beneath it. Bitumen membrane at SAR 15–35 per m² and XPS boards at SAR 10–30 per m² are options where insulation or a thicker protective layer is needed.
Owners who avoid the most common problems tend to share a few habits. They do not skip crack repair and coat over a split slab, because the water simply finds another route. They do not apply a coating to a damp surface, since trapped moisture causes bubbling within weeks. They do not choose the cheapest option without checking how the finish will handle foot traffic and cleaning during term time. And they do not leave balcony drainage outlets blocked or undersized, which is one of the quickest ways for ponding to undo good workmanship. Planning these details before work begins keeps the floors dry and the building in use throughout the school year.
For schools, the larger jobs are planned for weekends and holidays.
Signs worth paying attention to
The following signs are worth checking before they grow:
- Damp under the light well
- A wrong fall towards the door threshold
- Water passing from the balcony to the floor below
Where the problem usually comes from
- A blocked drain — we check this before anything else.
- Incorrect falls.
- A common cause: a threshold without waterproofing.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
How the work is done, step by step
- Checking the falls: Where water collects and where it should go.
- Details: Thresholds, drains and upstands.
- Waterproofing: The layer is applied and protected.
- Flood test: Tested before the finish goes on.

Short answers for Madinah
What is the difference between standard spraying and integrated pest management?
Standard spraying treats visible symptoms only, while integrated pest management includes diagnosis, sealing entry points, and multiple methods for longer-lasting results.
Could the leak be caused by weak waterproofing rather than the pipes?
Yes, damage to the waterproofing layer beneath the bathroom floor is one of the most common causes of leaks, especially in older buildings. In this case, water seeps through the tile joints into the screed and then down to the ceiling below. A specialized inspection can distinguish this from a pipe leak.
What is the difference between drain unblocking and drain cleaning?
Unblocking removes an existing blockage that prevents drainage, while cleaning is a preventive procedure that removes deposits and grease from pipes before they cause a blockage.
What is the first step of floor & balcony waterproofing for schools?
We start with checking the falls (where water collects and where it should go), then details (thresholds, drains and upstands).
