A: Landscape Tanks are made from 40mpa concrete and as such do not require sealing.However some external finishes may require a seal prior to application.See label for details.
Q: Do I need to prepare footings for the installation of the tanks?

Internal plumbing is pushed into place and the lids are then placed into position. Access of 2 metres wide by 2 metres high is all that is required.
Q: Do I need drainage around the bottom of the tank as with conventional retaining walls?
A: If the Landscape Tanks are to be used as retaining walls drainage is required. Aggie pipe surrounded by aggrigate as with standard retaining walls is ideal. Engineering drawings and computations are available on request.
Q: Can I have a deeper planter bed top?

Q: Can I store grey water in the tanks?
A: Grey water should not be stored for more than 24 hours because of the potential for deadly bacteria build up in the water.It is not recommended tanks be used for grey water.
Q: What are the delivery times?

Q: How long can I expect my tanks to last
A: Landscape Tanks are manufactured to Australian standard and as such have an "Implied" lifetime of over fifty years. A Landscape Tanks can be expected to outlast numerous timber or even brick retaining walls making the Landscape Tanks excellent value for money.
