Tank services are often confused. Understanding the difference helps you ask for what you actually need.
Cleaning and washing
Removing sediment and dirt and washing the tank walls and floor. Suitable as routine maintenance or when you notice sediment.
Disinfection
An additional step after cleaning using dedicated products, offered on request where available.
Waterproofing
A layer that stops water leaking out and groundwater seeping in, applied to a structurally sound tank or after repair.
Repair and rehabilitation
Treating cracks and damage in the tank walls. Usually comes before waterproofing when cracks exist.
