Water tank waterproofing in Alqunfudhah: the local context

The centre of Alqunfudhah sits about 7 m above sea level (SRTM open elevation data). Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

Team note on Alqunfudhah: 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..

Alqunfudhah sits about 7 m above sea level, and its centre is roughly 0.4 km from the sea coast. That combination matters for water tanks. Sitting close to the coast means the air carries salt and humidity, which can slowly attack exposed coatings, fittings and concrete surfaces. Because the land is low and close to the water, tanks here are often under constant exposure to moisture, so a small defect can stay damp for longer and spread further than it would inland.

These two facts shape how we approach the work. Salt-laden air means we check the external skin and the roof seams as carefully as the inside, since salt can creep into hairline gaps and accelerate corrosion of metal supports. The modest elevation means water does not drain away quickly from low spots on the roof or around the tank base, so we pay close attention to where water pools after rain and make sure those areas are sealed and sloped correctly. Owners in similar coastal-adjacent districts often find that a periodic inspection catches problems at the stage when a repair is a small, targeted job rather than a full recoating.

Owners often make the same few mistakes, and a preventive check is designed to avoid them. The first is waiting for a visible leak before inspecting, when water has usually already passed through the structure. The second is patching a single crack without checking the surrounding surface, which lets the failure simply move a short distance away. The third is ignoring the roof because it is out of sight, even though liquid roof waterproofing and bitumen membranes are the first line of defence against rain and salt spray. The fourth is choosing a coating only by price, without matching the product to the exposed surface. A regular check lets the right repair be chosen early and kept in proportion to the actual condition of the tank.

Preventive checks follow a written schedule instead of waiting for a fault.

Signs that call for water tank waterproofing

These are the signs most often linked to water tank waterproofing:

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

Where the problem usually comes from

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

Tools we use in Alqunfudhah

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.
