What is specific about Albaha for water tank waterproofing

Team note on Albaha: 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 Albaha sits about 2178 m above sea level (SRTM open elevation data).

The first thing checked on a water tank job in Albaha is altitude, because the centre of Albaha sits about 2178 m above sea level (SRTM open elevation data). At that height, the local climate and the way water is supplied both shape how a tank performs, so the technician looks at how the tank is filled and how it is used before deciding on a coating. Tank internal coating is priced at SAR 25–60 per m², and the choice between products starts from the condition of the existing lining rather than from a fixed rule. The reason for checking this first is simple: a coating that suits a tank filled on a steady schedule may not suit one that is drained and refilled often.

Some points can only be settled at the site visit. The technician needs to see the tank itself, measure its internal surface, and find out whether there are cracks, flaking or staining. Crack injection is priced at SAR 40–120 per metre, so the length of any crack is one of the first things measured. The inside of the tank also has to be checked for damp patches, loose material and signs that the lining has lifted from the walls. The access route, the height of the tank and whether it can be emptied are also judged on the day. Epoxy coating (SAR 35–90 per m²) and spray foam (SAR 20–45 per m²) are each suited to different surfaces, so the final choice depends on what is found in person rather than on a quote made from a distance.

Information that helps the technician is worth gathering before the visit. Tell us the age of the tank, what it was built from, and when the lining was last renewed, if you know. Note whether the water is drawn from the tank every day or only occasionally, and whether the tank sits on the roof, at ground level or below ground. If there has been any leak, record where it appeared and how quickly the water level dropped. Clear photographs of the tank interior and of any cracks help the technician prepare the right materials. Keeping access to the tank open on the day of the visit, and emptying it where possible, saves time and lets the work begin as planned.

In a duplex, the two floors often share lines, so tests are done floor by floor.

When do you need 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.
• Construction joints.

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.
