What is specific about Bishah for water tank waterproofing
Main roads in or near Bishah: King Saud Road, Riyadh Street. The centre of Bishah sits about 1169 m above sea level (SRTM open elevation data).
The facility manager of a school in Bishah usually inherits a water tank that has been in service for years, often on a rooftop or in a ground-level reservoir that supplies washrooms, kitchens and sports facilities. Daily use, staff turnover and a busy calendar mean that leaks are often noticed late, once staining has appeared on classroom ceilings or pump rooms have turned damp. The owner needs a plan that protects the tank without disrupting term time.
Bishah sits at about 1169 m above sea level, which is a useful fact for planning. Sites at this altitude see strong day-to-night temperature swings, and those repeated expansion and contraction cycles tend to open hairline cracks in concrete and loosen old coatings over time. For a school, this means the tank lining and the roof or slab beneath it should be inspected as a single system rather than in isolation. Costs also vary widely by method, so the facility team should match the scope of work to the actual condition rather than assuming a full replacement is needed.
A sensible sequence starts with a full inspection of the tank interior and the surrounding surfaces, marking every crack and any area where coating has lifted. Next, cracks should be sealed by crack injection, which is priced per metre, and the internal surfaces then treated with tank internal coating, priced per square metre. Where the roof or slab above is exposed, liquid roof waterproofing or a bitumen membrane can be applied, and bathroom or basement areas served by the same supply should be checked and treated where needed. Finally, the owner should schedule a re-inspection after the first full season and keep a simple written log of any new damp patches so that small problems are caught before they spread.
For schools, the larger jobs are planned for weekends and holidays.

How we choose the tool in Bishah
| 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 |
| Crack injection (polyurethane or epoxy) | Stopping active water through cracks | Limits: treats the crack, not the water source |
| Fill test with level monitoring | Whether a tank coating holds after the work | Limits: takes time to monitor the level |
How the work is done, step by step
- Emptying and ventilation: The tank is emptied and ventilated before entry.
- Cleaning and preparation: Loose material is removed down to a sound surface.
- Crack treatment: Active cracks are treated first.
- Coating layers: A material intended for drinking-water tanks is applied.
- Disinfection and fill test: The tank is disinfected and the level is monitored after filling.
