Cover the deco and crusher dust base with black builders plastic to prevent the tank being undermined in the event of torrential rain. You can purchase the black builders plastic at your local hardware store.
This firm stable platform must be of dimensions 250mm larger than the tanks diamensions.
Alternatively a properly constructed stand capable of carrying the weight of the tank when full using 1kg per litre as a guide.
These recommendations apply to all of our tanks regardless of the material used for construction.
If you have a difficult site or are unsure as to what is required call us and we will be happy to advise you.
Please note: overflows must be connected and discharged away from the base of the tank to prevent undermining.
