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).
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.
Please contact the Cordek Technical Team for assistance with determining the suitability of Sacrificial Guide Wall Formers in relation to the project they are being considered for.
The manufacture of Filcor is a low pollution process. Steam is he key component and the water is re-used many times. There is no waste in the process as all cut offs or rejects are recycled.
Filcor is 98% air. This makes Filcor a uniquely resource-efficient material with small carbon footprint.
Filcor is HFC, CFC and HCFC free and Pentane is used as its blowing agent. Pentane has a low Global Warming Potential* (GWP) of less than five. (The EU does not register pentane as a substance hazardous to human health or environment.)
Styrene, used in the manufacture of Filcor, occurs naturally in many commonplace items including strawberries, beans, nuts, beer, wine, coffee beans and cinnamon
