Promax Corrugated tanks are so tough you can bury them up to 1 metre in the ground - and they still retain their 20 year warranty!

Often a project can have height restrictions but also the need for a large amount of water storage - the Promax Corrugated big tanks are a perfect solution to this problem.


Promax Underground tanks are vehicular traffic approved - tested to AS/NZS 2566:1-1988 with a load rating of 28kpa.
