Water tank waterproofing in Tarout: before summer & rain season

What is specific about Tarout for water tank waterproofing

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

Main roads in or near Tarout: Uhud Road, Al Khaleej Road, Al Aimmah Bridge. 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..

Before any coating goes on a water tank in Tarout, the first thing we check is how close the site sits to the coast, because that shapes how we read the tank's condition. The centre of Tarout sits about 3 m above sea level, and the town is about 0.9 km from the sea coast. That combination means salt-laden air and moisture can reach tank surfaces and roof fixings, so we look for salt crust, rust staining on supports and any sign that damp has been working into the concrete or steel for a long time. Because the town is low-lying, we also check how rainwater runs off the roof and whether it pools around the tank base, since standing water in the rain season is a common route for leaks.

Some things can only be settled on the day, once we are standing next to the tank. We inspect the tank walls and floor for cracks, check whether the existing lining is lifting or blistering, and decide whether the surface needs grinding or a patch before any new layer goes on. Access, the height of the tank, whether it holds potable water or non-potable water, and the state of the roof slab are all judged in person. Scope and cost depend on these findings, so any quote we give before the visit is only a rough starting point. Ranges such as liquid roof waterproofing at SAR 8–25 per m², tank internal coating at SAR 25–60 per m², or crack injection at SAR 40–120 per metre only become meaningful once the measured area and the actual defects are known.

To help the technician, it is useful to have the tank's approximate size and capacity ready, a note of when it was last cleaned or recoated, and any photos of leaks or staining taken after recent rain. Tell us if the tank sits on a roof, at ground level or partly below ground, and whether there is a water pump, a ladder or a manhole that affects access. If the tank was installed with an insulation board or an older membrane, mention that too. Clear notes like these let us bring the right materials, from epoxy coating at SAR 35–90 per m² to bitumen membrane at SAR 15–35 per m², and complete the job before the summer heat or the rain season arrives.

Checks before summer and before the rain season catch problems while they are still small.

Signs that call for water tank waterproofing

The following signs are worth checking before they grow:

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

The most common causes

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

Tools we use in Tarout

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.
