Your steel liner tank will arrive on your site as a kit. It is recommended that it is only installed by qualified and experienced installers.

The Liner

Arguably the most important part of your steel liner tank, is the liner. It not only needs to be super strong, but BPA free, lead and phthalate free, water potable certified, chemical and stress crack resistant, plus able to withstand harsh conditions, -40°C to +70°C, and we can say the liner we use is all this and is proudly Australian made. A unique 7 layer liner made to the highest quality.

Pad Preparation

Your steel liner tank arrives as a kit. Installation starts with the proper preparation of the pad on which it will sit. This is the responsibility of the owner.
Use sand or crusher dust for the pad, to a depth of at least 150mm, compacted to a minimum capacity of 50kPa. Ensure there are no sharp objects in the pad. The pad is to be at least 2 metres wider than the diameter of the tank. If using crusher dust, ensured it is screed, removing anything over 5mm long. A geotextile covering over the crusher dust is recommended. It is essential that the pad is level.
Once tank is installed, the owner is responsible for adding at least 300mm of water into the tank. This helps correctly position the liner and provides weight, should strong winds eventuate.
To prevent erosion of the sand, around the tank, from overflow from the roof, blue metal or aggregate should be spread, 75mm thick, 40mm wide around the whole tank, to handle the drainage.
