Continuous Flight Auger Piles

Continuous Flight Auger (CFA) Piles are built by drilling a hollow-stem auger into the ground to form the pile’s diameter and a concrete pump is utilised to deliver concrete through the hollow auger stem to the pile.

Pile diameters range from 300mm to 1.2 m.
Piling Lengths range to 36 m.
Rig weights range from 11t to 160t.

Applications

CFA Piles can be installed quickly and inexpensively without significant vibration or excessive noise being produced. They are ideally suited for most soil types. Avopiling’s own design of drilling tools is capable of drilling into certain rock layers. Once desired pile level is achieved sand-cement grout or special concrete mix is then pumped into the hole through the hollow stem of the auger while being extracted, eliminating the need for temporary casing and making them ideal for non-cohesive or water bearing soils.

CFA System is ideal for foundation piles and for embedded retaining walls such as contiguous and secant piled walls.

Advantages

Low noise and vibration
Works well in non-cohesive soils
Cost-effective
Minimal site preparation
Suitable for tension loads
Can be installed successfully into most ground conditions
Ideal for foundation and piled earth retaining systems
