Bored Piles

Continuous Flight Auger (CFA) piles

Piles are constructed by drilling with a continuous flight auger to the designed depth. Concrete is then pumped through the hollow stem of the auger during its extraction. CFA enables rigs to place concrete below groundwater level, eliminating the need for casing.


Amplus offers a full-range of mini-piling services using rotary percussive, down-the-hole hammer and augers.

The diameter, depth of mini-piles and need for casing are determined by ground conditions and the size of the rig that can access the location.
