Water tank waterproofing in Albaha: the local context

The centre of Albaha sits about 2178 m above sea level (SRTM open elevation data). 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..

At a school in Albaha, the first thing a technician checks is the height of the site, because the centre of Albaha sits about 2178 m above sea level (SRTM open elevation data). At that altitude, the air is thinner and the weather patterns differ from the coastal cities many people know, so the team looks at how the tank has been exposed to sun, wind and temperature swings before choosing a system. The condition of the tank's internal surface also comes first, since a school tank is used every day by many people and any failure affects the whole building. Technicians note which areas are already damp, where old coatings have lifted, and whether previous repairs have trapped moisture underneath.

Several details are left to the site visit, because they cannot be judged from a distance. The technician measures the tank's internal surface area in square metres, identifies any cracks and measures their length in metres, and confirms whether the tank is cast concrete, block or another material. The cost of each option is set by the scope the team finds on the day. For example, tank internal coating is priced at SAR 25–60 per m², crack injection at SAR 40–120 per metre, and epoxy coating at SAR 35–90 per m², so the final figure depends entirely on how much of each treatment the tank needs. Where the tank connects to a basement or a roof, the team also checks those areas, since basement waterproofing (SAR 50–150 per m²) and liquid roof waterproofing (SAR 8–25 per m²) are separate jobs.

To help the technician, school staff should prepare a few simple things before the visit. Share access details, the date the tank was last cleaned or emptied, and any record of past leaks or repairs. Make sure the tank can be drained or isolated for inspection, and tell the team when the water supply to the school can be interrupted. Point out any rooms or walls where dampness has appeared, even if the source is unclear. Clear information at this stage lets the technician compare the on-site findings with the price ranges and select the system that fits the tank, the building and the altitude of Albaha.

For schools, the larger jobs are planned for weekends and holidays.

Signs that call for water tank waterproofing

If you notice one of these signs in Albaha, it is a good moment to talk to the team:

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

Causes we see in the field

• Damaged old coating.
• A common cause: cracks in the walls or floor.
• Construction joints.

Tools and methods, and when we use them

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.
