Water tank waterproofing in Tarout: preventive periodic check

Before we start: what we know about Tarout

Team note on Tarout: 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 Tarout: Uhud Road, Al Khaleej Road, Al Aimmah Bridge.

The centre of Tarout sits about 3 m above sea level (SRTM open elevation data). Tarout is about 0.9 km from the sea coast (OpenStreetMap).

Tarout is an island town on the Gulf coast of Eastern Province, and its centre sits about 3 m above sea level, which is low enough that the local ground and groundwater stay damp for much of the year. The sea coast is also only about 0.9 km from the town centre, so homes and rooftop tanks here are exposed to salty, humid air that speeds up corrosion and the breakdown of coatings. For a water tank, this means the surface seals and joints face a harder life than they would further inland, and a yearly look at the tank's condition is more useful here than a check left until a leak appears.

Those two facts shape the practical work. Because the ground sits close to sea level, moisture can move into the base of a tank, and a tank internal coating, priced at SAR 25–60 per m², should be inspected for blistering or lifting where water collects. Because the coast is close, salt-laden air attacks external surfaces, so the outer walls, lids and any exposed bitumen membrane (SAR 15–35 per m²) need checking for cracking or peeling. Where a hairline crack is found, crack injection at SAR 40–120 per metre is usually a quicker repair than replacing a large section, and a sound seal can stop a small problem growing into a costly one. The same logic applies to any roof surface beneath or beside the tank, where liquid roof waterproofing at SAR 8–25 per m² may need touching up.

Owners in Tarout commonly make a few avoidable errors. The first is waiting for water to show on a ceiling before acting, when moisture has often travelled for weeks through the structure. The second is covering a damp or dirty surface with new coating, which traps water underneath and causes the layer to fail early. The third is ignoring the tank lid and inlet seals, since salt and dust can loosen them without any visible crack. The fourth is treating a single repaired spot as the whole job, when the surrounding coating may be just as worn. A short periodic check, recorded each year and repeated after strong winds or heavy rain, lets you spot these signs early and keep the tank sound in a coastal setting.

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

Signs worth paying attention to

If you notice one of these signs in Tarout, 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 — we check this before anything else.
• A common cause: damaged old coating.
• Cracks in the walls or floor.

Tools we use in Tarout

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.
