Bored Piles are circular piles made of concrete and steel being installed in the soil by various drilling
When the piles are side by side and not linked together they form a retaining wall for excavation pits or terraces. Depending on the application of the contiguous pile walls, the length, diameter, material, formation, and placing of the individual piles can be adapted to meet many different requirements.
This can be done via:
- Kelly Method
- Continuous Flight Auger
- Rotary Twin System
Each one has it own advantages and disadvantages.
