Cased Flight Auger Piling or CFA through Casing

This equipment and methodology has been designed to enable flight auger piles to be constructed with the added benefit of temporary casing, and permanent casing if required, which can be installed to a depth of 16.0 metres with the finished piles to a depth of 27.0 metres.

The auger is still offered in sections as are the casings in this instance.

Benefits include:

  • CFA piles may be terminated at any desired level below piling platform level
  • Improved verticality for CFA piles
  • The ability to insert longer reinforcement cages
  • The ability to install permanent casing using the CFA method
