Auger Cast Pilling (2-Hour Live Webinar)

Andres Baquerizo, PE

Auger cast piling, also commonly referred to as Continuous Flight Auger (CFA) Piling, are cast in place piles, using a hollow stem auger with continuous flights. The auger is advanced into the soil to a designed depth and the concrete or grout is pumped through the hollow stem, maintaining a head pressure to fill the cylindrical cavity created as the auger is slowly removed. The pressure and volume of the grout must be carefully controlled to construct a continuous pile without defects. A reinforcing cage is placed through the freshly placed concrete/grout to the design depth. Auger cast piles are commonly used are to provide structural support but can also be used to provide earth retention, especially on-site boundaries. This type of installation can be a very cost-effective foundation system and should be consider in the correct applications. This presentation will review when that it is and how auger cast piles may benefit your projects.

Keller North America provides a wide range of geotechnical engineering and construction services to improve soils in-place and to both construct new and to rehabilitate foundations. Within our range of services, a Ground Modification solution is generally available for the toughest subsurface conditions.
