Sacrificial Guide Wall Formers

Sacrificial Guide Wall Formers are used to accurately form an in-situ concrete guide wall which is critical in the positioning and alignment of piles in a contiguous or secant piled wall. From a customer’s pile layout plan Cordek will produce a drawing detailing the size, shape and position of each former. After customer approval of the layout drawing each former is CNC cut from a solid block of Filcor (Expanded Polystyrene).


  • Improves the accuracy of pile guide wall construction
  • Can be used with both secant and contiguous pile wall constructions
  • Can accommodate most pile designs, including curved and circular pile walls
  • Quick and easy to install for rapid guide wall construction

The formers are designed for a single use only and do not need to be struck from the finished guide wall which allows the piling rig to auger directly through the formers.


For the formation of guide walls to allow the accurate positioning and alignment of both contiguous and secant piled walls.
