Duracrete Concrete Water Storage Tanks


Duracrete Products are continually improving the quality, strength and durability of our water tanks through modern technologies. Our efforts have been recognised by the NZ Concrete Society, by being awarded the 2003 Technology Award for outstanding innovation, in the advancement of concrete practice in design and construction.


Advantages of Duracrete Tanks

  • Provides a cool, clean and healthy environment for household water
  • Will not fail in the event of a fire
  • Does not need protecting from stock
  • Does not require anchoring restraints in high wind areas
  • Can be buried or partially buried in confined or restricted situations
  • Manufactured from natural raw materials produced within New Zealand

For Dependability


Concrete has been used over many centuries, as far back as Roman times and has proved to stand the test of time. During periods of disaster such as fire, flooding, cyclones or earthquake, drinking water is crucial for survival. Duracrete concrete tanks offer a secure water storage option.


For Performance


Duracrete concrete storage tanks can be used in many situations for reliable and convenient water storage. They provide high strength for buried or partially buried applications, including uses in industry, agriculture, horticulture and domestic households.
