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 or 4ft centres for imperial 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 or 4ft centres for imperial 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 or 4ft/2ft centres for imperial panels. This arrangement becomes necessary where access is restricted due to primary supports at 500mm centres.

Space requirements for installation 

 

A B C D
Tanks up to 3m deep 600 425 750 500
Tanks 2m – 2.5m deep 600 525 750 500
Tanks 3m – 4m deep 600 625 750 500

Clearance dimensions in mm
Clearance may be varied by agreement for small tanks where access is deemed suitable.
Ladders with hoops will require a space of at least 1030mm.

Internally flanged base, Internally flanged (IF) and Totally internally flanged (TIF) tanks

Option 1 Concrete plinth
Flat concrete plinth- ensuring the plinth is level and that it extends 150mm beyond the tank internal length and width dimensions
