Concrete is a composite material consisting of naturally occurring sands and gravels merged together with a fluid cement. This substance then hardens over time through a process called “hydration”, which solidifies the substance to concrete. Concrete is the most used, man-made product in the world and is extremely durable, which makes it a perfect product for the construction of water storage tanks. It is capable of withstanding fire, heat and ground movement and is a natural insulator, with the ability to keep stored water at a relatively constant, cool temperature in a dark environment which controls any algae growth. Heal offers a range of differing concrete tanks which can be tailored for any given requirement, please feel free to enquire for further information.
