• Silos: Would you select Horizontal or Vertical?

For your consideration, we offer here a simple comparison of the two silo types. We think the case for horizontal is stronger and well worth considering even though the capital cost is higher.

20 Tonnes capacity horizontal cement silo mounted on load cells.

Typical Load Cell Mounting Detail


  • Looks like a standard HQ container and can be transported on a container truck.

  • Low profile helps the visual look of the site and makes it safer for roof access

  • Load cell mounting provides real time weight based measurement of its contents and can be integrated into existing systems

  • Aeration and vibration ensures the product settles into the integrally built discharge screw conveyor

  • Easy to install, lower installation cost and requires only a Franna with spreader bars to position it

  • Can be located anywhere close to the batch plant and does not need heavy foundations

  • Easy to maintain and reach the accessories

  • Needs no special council permissions as it can be easily re-located

Cons: - yes, there are always these but, in this case, there is only one!

  • The capital cost is higher than a bolted silo

Typical 55 tonnes capacity vertical bolted silo


  • Segmented manufacture

  • Bolted construction

  • Transportable in a 20’ container

  • Can be assembled with unskilled labour

  • Lower capital cost than a horizontal silo


There are a few of these!

  • Many components to assemble = longer time = more money

  • Care needed when assembling the wall segments to make sure all joints are tight with the rubber gaskets supplied.

  • Any leaky joints and water will seep into the cement

  • Many Boxes of bolts and nuts – enough to drive one “nuts”

  • Visually intrusive

  • Requires a large foundation to withstand wind loads

  • Will need council approval due to its size.
