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.
Our factory manufactures various type of CFA drill rod and head matching with different drilling rigs, which can perform well in different soil conditions.
