Sectional Tank Installation Guidelines

The tank type determines the type of foundation that may be used for installation. Base guidelines are provided for each tank ordered.

Externally flanged base tanks 

Option 1 – Solid bearers 
Concrete dwarf walls – placed at 1000mm centres for metric tank panels.  As space is required underneath the tank, externally flanged base tanks must be placed on an elevated structures outlined in the image.

Option 2. Steel supports 

Parallel steels beams placed on raised steel supports. Steels placed at 1000mm centres metric tank panels.

Option 3. Secondary Steels 

Concrete dwarf walls with parallel steels running perpendicular to dwarf walls. Primary walls centres no less than 750mm. Steels placed at 1000mm/500mm centres metric tank panels. This arrangement becomes necessary where access is restricted due to primary supports at 500mm centres.
