Continuous Fight Auger (CFA) piles were first used in Europe over 25 years ago. Similar technology has been used in the United States under the product name Auger Cast-in-Place (ACIP) Piling. The introduction of CFA piling to Western Canada began over 5 years ago and they have been used on a variety of commercial and industrial structures. Numerous load tests have been conducted in soft marginal soils, weak rock, and dense glacial tills common to Western Canada. CFA piles are an excellent alternative for sites where other deep foundation methods would either be too costly or take too long to construct. This presentation will describe the following as it applies to CFA piling: when they should be used, the design and installation methods, the load test history in Western Canada, the concrete mix design and steel reinforcement details used for successful installation, and quality control methods used during construction.
