CFA Piling Continuous Flight Auger

This is a method that will suit semi-open and open sites such as new builds. The piling rig that can be used, dependent on the pile specification, is from-15 Ton up to 60-Ton rigs. A string of auger goes into the ground as one hit and depending on the piling rig specification, strings of augers can be ranged from 12m down to 25m including a special kelly bar which will push augers down. This is a quick method of piling, taking only 10-15 min for a pile including concreting (again we can leave the borehole open or we can concrete the borehole through the middle of augers). Pile diameter from 300mm to 600mm.
