Tank PAD Preparation (Rural)

Learn more about the various methods to prepare the base of your tank for installation to ensure a correct foundation is laid.

Pad Preparation Guidelines

The preparation of the base pad is the responsibility of the customer. Our preferred base material is free draining sand. It must be free of sticks, stones and clay lumps. If you have to cut or fill the site, ensure adequate compaction of the sub soil to avoid subsidence.


The pad must be level to +/- 10mm.
