Water tank waterproofing in Sabya: the local context

Team note on Sabya: 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.. Main roads in or near Sabya: King Fahd Road, King Abdulaziz Road, King Abdullah bin Abdulaziz Road.

The centre of Sabya sits about 40 m above sea level (SRTM open elevation data). Sabya is about 16.7 km from the sea coast (OpenStreetMap).

Clinics in Sabya usually run into the same problem with their water tanks: leaks and seepage that start small and then spread. Water tanks in clinics are used for handwashing, sterilisation, and sanitary fixtures, so a slow leak can affect hygiene as well as the building. The usual cause is a cracked or porous concrete wall that lets water seep through over time, often hidden behind a wall or under a slab. Clinic staff may notice damp patches, a drop in water pressure, or a constant need to top up the tank before anyone sees the actual wetness.

Sabya's location shapes the approach. The centre of town sits about 40 m above sea level, and it is about 16.7 km from the sea coast. Because the town is inland and fairly elevated, a tank here is less exposed to the salt-laden coastal air that can speed up corrosion along the coast, so the focus shifts toward the tank's own concrete and joints. Many clinics also share a building with other tenants, so work that involves draining and opening a tank needs careful timing. Coating the internal surface of the tank, usually priced at SAR 25–60 per m², is a common route, while crack injection is charged at SAR 40–120 per metre when a specific seam is the problem. Clinic owners should compare these options against the actual condition of the tank rather than choose one by default.

Before the visit, ask the contractor to confirm the tank's capacity and how it is accessed, and whether the tank can be fully drained and kept empty for the work. Ask how they will protect the clinic's water supply for patients and staff while the tank is out of use, and when they can schedule the work around clinic hours. Request a written breakdown showing which rates apply to the tank interior, any crack repairs, and any work on surrounding areas such as a basement or bathroom, so the quote matches what is needed. Finally, ask how the surface will be tested before it is refilled, since that step tells you whether the repair has solved the leak.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

Signs worth paying attention to

The following signs are worth checking before they grow:

• 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 — we check this before anything else.
• Damaged old coating.
• Cracks in the walls or floor.

Tools we use in Sabya

How the work is done, step by step

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.
