Bored piles

Coming to the point.

Bored piles and large-diameter bored piles are primarily used as foundation elements where heavy loads need to be transferred to deeper levels where the soil has a greater load-bearing capacity.

The following foundation types may be used:

  • Single-pile foundations with punctual load distribution
  • Pile group foundations with broad load distribution
  • Special case: combined pile plate foundations

Bored piles are rigid and can absorb both vertical and horizontal loads. The fabrication process allows for flexible adaptation to suit the required pile length and diameter. Owing to the lack of vibration and noise generated in fabricating bored piles and their resistance to settlement, this option is ideally suited to inner-city use.

Common fabrication methods include:

  • Standard pile methods using kelly rotary drills with cased boring or suspension-supported boring
  • Gripper boring procedures with casing machines
  • Continuous flight auger piles (CFA-piles)

Bored piles are usually made with the use of advance casing, which is in turn drilled into the subsoil. The soil material is extracted from inside this tubing using an auger drill or drilling bucket.

Once drilling is complete, a reinforcement cage is inserted and in-situ concrete poured through a tremie pipe.
