Concrete Water tanks

Issues with Concrete water tanks  

Concrete is a strong material but it has limited flexibility. This means that as the water tank naturally contracts and expands over time, the concrete becomes weaker. Eventually this can lead to leaks and cracks in the walls of the tank. Leaks like this can lead to further issues including bacteria contamination and water damage. 

Concrete is a porous material and over time can become a breeding ground for Legionella and other waterborne bacteria. If the water stored in the concrete tank is acidic, it can leach the calcium carbonate from the concrete into the water, resulting in hard water.
