Before we start: what we know about Aldiriyah

The centre of Aldiriyah sits about 655 m above sea level (SRTM open elevation data). Team note on Aldiriyah: 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..

Is it worth waterproofing a school water tank in Aldiriyah, and what will it cost? The centre of Aldiriyah sits about 655 m above sea level, and a tank that holds water for a whole building needs to stay sound year after year. Tank internal coating typically falls in the range of SAR 25–60 per m², while epoxy coating runs SAR 35–90 per m². Those figures let a facilities manager compare options before any work is booked, and they show that the right coating depends on the tank's condition and the surface area involved.

The inspection starts with a walk around the tank and a check of its inside surfaces for cracks, flaking, and damp patches. Where a crack is found, crack injection is quoted at SAR 40–120 per metre, so the length of each defect matters to the final figure. The inspector also looks at the tank roof and any exposed upper surfaces, where liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² may be considered. Measurements are recorded for each area so that the quote reflects the real work rather than estimates.

Before the visit, the school should prepare clear access to the tank, its roof, and the plant room, and arrange for someone who knows the building to be present. It helps to have any earlier repair records, a note of where leaks or stains have been seen, and the dates when they appeared. If the tank has been drained recently or is planned for cleaning, tell the inspector in advance so the work can be scheduled around the school timetable. With these details ready, the site visit can move quickly and the written proposal will match the school's actual needs.

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

Signs worth paying attention to

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

• Unusual colour or taste in the water
• A tank that leaks after testing
• Deposits and flaking inside the tank

Where the problem usually comes from

• Construction joints.
• Damaged old coating — we check this before anything else.
• A common cause: cracks in the walls or floor.

Tools and methods, and when we use them

The steps in order

1. Emptying and ventilation: The tank is emptied and ventilated before entry.
2. Cleaning and preparation: Loose material is removed down to a sound surface.
3. Crack treatment: Active cracks are treated first.
4. Coating layers: A material intended for drinking-water tanks is applied.
5. Disinfection and fill test: The tank is disinfected and the level is monitored after filling.
