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..

Water tank waterproofing in Alqunfudhah starts with the location itself. The centre of Alqunfudhah sits about 7 m above sea level, and the town is about 0.4 km from the sea coast. Because the site is so close to the coast, the technician should treat salt-laden air and ground moisture as a real factor when checking the tank, rather than assuming a dry inland environment. The first checks should therefore look at the tank's internal surfaces, the joints and the lid, with attention to any signs that water or damp has already reached the coating or the concrete beneath it.

Several things are left to the site visit, because they cannot be judged from a description. The technician should inspect the actual condition of the tank walls and floor, note the size and depth of any cracks, and confirm which surfaces are exposed to water and which are only exposed to air. The choice of coating depends on these details, as does the decision between treating the inside of the tank and repairing the structure around it. Access, the tank's current contents, and whether the tank can be emptied and dried before work begins should also be assessed on site, since these determine how the job can be sequenced.

For the technician, the most useful information is a clear picture of the scope before any materials are chosen. Record the tank's internal surface area, the length of any crack that needs injecting, and whether the warehouse roof or adjoining basement shares any surface with the tank. Note that internal tank coating is commonly priced between SAR 25 and SAR 60 per m², and crack injection between SAR 40 and SAR 120 per metre, so measuring these quantities accurately on the day will make the estimate far more reliable. Keeping these measurements, along with photographs of the tank's condition, gives the client a transparent basis for the work agreed.

For warehouses, work is phased around operations and stored goods.

When do you need water tank waterproofing?

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

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

Causes we see in the field

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

Tools and methods, and when we use them

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.
