Bored Piles

Also known as drilled shafts or cast-in-place concrete piles, bored piles are constructed by excavating a slender, cylindrical hole and backfilling the excavation with a reinforcing cage and concrete. Their load-bearing capacity is either derived from skin (side) friction between the concrete and the surrounding soil, is end bearing, or a combination of both.

Advantages:

  • The construction process generates less noise and vibration compared to other methods.
  • On-site engineers can observe the soils that are excavated, enabling a comparison of anticipated soil conditions.
  • Design changes (e.g. increase/decrease length, increase/decrease diameter) can easily be incorporated in the field.
  • Bored piles can be installed in most soil types, including cobble and boulders, and even into competent bedrock.
  • One large capacity bored pile can replace the requirement for many smaller piles, eliminating the need for a large pile cap.

Applications:

  • Bored piles are ideal for large loads that require a single pile with a small footprint and adequate capacity to resist axial, lateral, and moment loads.
  • Bored piles are versatile in their design and construction and can therefore be used for commercial, industrial, and infrastructure applications.
  • They are great foundation elements for high rise buildings, arenas, bridge pier foundations, electrical transmission tower foundations, etc.
