CFA
Continuous flight auger (CFA) piles are a quick and economical solution suitable for most ground conditions and construction projects. It is also one of the quietest forms of piling methods which is virtually vibration-free. An ideal solution for projects in urban locations where noise levels need to be kept to a minimum.
WHAT THEY’RE USED FOR
This solution can be used in most ground conditions such as gravel, sand, silts, clay and low strength rock.
THE PROCESS
Continuous flight auger piles are a non-displacement technique. This means the soil excavated from the ground is brought to the surface and subsequently constructed using concrete/grout.
CFA piles are formed by drilling to the required design depth using a hollow stem continuous flight auger. This produces spoil arising from the bores. After reaching the required depths, concrete is pumped through the hollow stem. A reinforcing cage is then installed in the bore to form the pile.
