Sectional Flight Augered
- Mini Piles 200mm – 350mm diameter
- Midi Piles 200mm – 600mm diameter
Sectional Flight Augered Piles are constructed by drilling short sections of hollow stemmed augers into the ground (typically 1.0m – 3.0m long). Additional sections of augers are added to the drill string until the augers have reached the required depth.
Once at depth, concrete or cementitious grout is injected down the hollow stem of the augers to the pile under pressure.
The augers, filled with spoil from the drilling method, support the pile bore as they are withdrawn from the ground in a controlled manner.
