Water tank waterproofing for clinics in Jubail

Before we start: what we know about Jubail

Team note on Jubail: 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.. The centre of Jubail sits about 4 m above sea level (SRTM open elevation data).

Jubail is about 0.9 km from the sea coast (OpenStreetMap).

Water tanks at clinics in Jubail face a particular problem: because the centre of the town sits about 4 m above sea level, and the coast is only about 0.9 km away, the ground around a tank is often damp and salt-laden. Clinic tanks supply water for sterilisation, handwashing and treatment rooms, so a leak or seepage is more than a nuisance. The most common failure is moisture working its way through the tank walls and floor, leading to cracks, flaking coatings and contamination risk that is hard to spot until the damage is well advanced.

Because of these local conditions, the approach at a clinic in Jubail starts with the surroundings as much as the tank itself. Salt-laden moisture from the coast means the coating system must be chosen for the environment, not just the size of the tank. Tank internal coating is typically priced at SAR 25–60 per m², and an epoxy coating at SAR 35–90 per m², so the right system depends on how the tank is used and what the walls and floor are doing. Where cracks are present, crack injection at SAR 40–120 per metre is usually needed first, so the coating has a sound surface to bond to. Any sealing of the tank's external faces or nearby basement areas should be planned at the same time, using the basement waterproofing rate of SAR 50–150 per m² as a reference point for below-ground work.

Before the visit, ask the provider which coating system they recommend for a water tank in a salty coastal setting and why, and whether they will inspect for cracks before quoting. Ask them to explain how the work will be carried out without interrupting clinic operations, and how the tank will be cleaned and checked before it is refilled. Request a written breakdown by area and by method, showing the rate per m² or per metre for each item, so you can compare quotes on a like-for-like basis. Finally, ask what maintenance the clinic should carry out afterwards, and how often the tank should be inspected.

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

Signs that call for water tank waterproofing

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

The most common causes

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

How we choose the tool in Jubail

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.
