Floor & balcony waterproofing for schools in Hail
In short: In Hail (Hail), 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 Hail sits about 1002 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.
What is specific about Hail for floor & balcony waterproofing
The centre of Hail sits about 1002 m above sea level (SRTM open elevation data). Team note on Hail: 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..
Ponding water on school roofs and balconies is the most common problem we see in this property type. Flat floors and open walkways collect rainwater, and where drainage outlets are blocked or set too high, water sits on the membrane for days. Over time it finds hairline cracks around drains, parapets and joints, and the damage appears inside classrooms and corridors below. In a building used by many people every day, a leak that starts small can close rooms and disrupt lessons before anyone notices it.
Hail sits at about 1002 m above sea level, and that height shapes how we approach these jobs. Higher ground brings a wide daily temperature swing, so surfaces expand and contract more than they would in a lower coastal city. For that reason we pay close attention to movement joints and crack-prone edges, and we often recommend a flexible system such as a bitumen membrane or liquid roof waterproofing rather than a rigid finish that could split. Where balconies or walkways need a harder, easy-to-clean surface, epoxy coating can be considered, with the cost range depending on the area and the condition of the base. Crack injection, priced per metre, is used where a single defined line of movement is causing the leak.
Before the site visit, ask the provider to confirm which areas are included: roof, balconies, walkways or bathrooms, since each is priced differently. Ask how the existing drainage will be checked and cleared, and whether the outlets will be raised or reset to prevent future ponding. Request a written breakdown showing the per-square-metre or per-metre rate for each part of the work, and ask which materials are proposed so you can compare them with the building's needs. Finally, confirm when the work can be done without disrupting school hours, and ask who will be your point of contact during the job.
For schools, the larger jobs are planned for weekends and holidays.

Tools we use in Hail
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
The steps in order
- 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.

Questions from Hail
Is foam insulation suitable for Hail's dry climate and cold winters?
Yes, foam reduces heat entering in summer and limits heating loss in winter, but a suitable protective layer must be applied over it to resist strong sunlight.
Do bathroom leaks affect the safety of a building?
Yes, if they continue for a long time they can weaken the concrete, cause the reinforcing steel to rust, and spread moisture into the adjacent rooms. Therefore, early inspection is recommended as soon as the first signs appear.
How does Hail's climate affect epoxy flooring?
Heat and cold require choosing suitable materials and applying them under appropriate conditions to avoid bubbles and weak curing.

We start with checking the falls (where water collects and where it should go), then details (thresholds, drains and upstands).
