Description

CFA Pile, also known as auger cast piling or  cast-in-place piles, is a technique used in construction to create a concrete deep foundation. As it is cost-efficient solution and the low vibration nature, today CFA pile is a popular foundation type in construction. Continuous flight augers (CFA) consist of a hollow stem auger with continuous flights and head. It can be used to drill in most soil condition with diameter varies from 300mm-800mm. Once drilling to a specified depth, a high performance concrete is pumped through the hollow stem to then fill the cavity as the auger is extracted.
