Water tank waterproofing for schools in Samtah

Before we start: what we know about Samtah

Samtah is about 22.6 km from the sea coast (OpenStreetMap). The centre of Samtah sits about 61 m above sea level (SRTM open elevation data).

Main roads in or near Samtah: Al-Turshiyah and Al-Najmiyah Road, Samtah. Team note on Samtah: 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..

A school administrator in Samtah usually manages a site with several buildings, staff toilets, a kitchen, and one or more water storage tanks on the roof or at ground level. The tanks get heavy daily use, and a leak can quickly affect classrooms, stored supplies and the building below. Waterproofing a tank is often treated as a routine task, yet the condition of the lining decides whether water stays clean and whether the structure stays dry for years.

The local setting matters. The centre of Samtah sits about 61 m above sea level, so the town is not at the coast, but it is only about 22.6 km from the sea coast. For a school owner, this means the site is exposed to a warm, humid coastal air mass while still sitting on higher ground that can see strong sun and sharp temperature swings. Tanks expand and contract, and damp air can keep surfaces wet for longer, so a coating that suits a dry inland site may not last as long here. Checking the tank lining and the roof below it should be part of normal maintenance, not an emergency response.

Start by emptying the tank and inspecting every internal wall, floor and seam for cracks, lifting paint or soft patches. Clean the surface and let it dry fully before any product is applied. Next, seal any cracks with crack injection, priced per metre, and then apply the tank internal coating, which is priced per square metre and suits food-safe water storage when the product is chosen correctly. Where the roof above the tank is also affected, a liquid roof waterproofing system or a bitumen membrane can be added, and XPS boards may help with insulation where heat is an issue. Finally, refill slowly, check for leaks over several days, and record the date and scope of work so the next inspection has a clear reference.

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

Signs worth paying attention to

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

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

Where the problem usually comes from

• Cracks in the walls or floor.
• A common cause: damaged old coating.
• Construction joints.

Tools and methods, and when we use them

From the first visit to the report

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.
