Piling - large diameter bored piles

Large diameter bored piles are widely used in civil engineering and have range of applications and they can act as containment for ground work or for foundations.They can be divided in two main types:

  • Bored piles
  • CFA (Continuous flight augers)


  1.  Digging the pile: dry; Using Bentonite; Biodegradable polymers;
  2. Cleaning excavation and displacing the slurry;
  3. Placing a reinforcement;
  4. Concrete casting;
  5. Cropping piles (cutting the pile);
  6. Load test


  • Pile diameter: 500 to 2500 mm
  • Depth: 75 ≈ m
