Bored piles, also called as replacement piles are used for building a firm foundation to provide support and structure to the complete building. With high bearing capacity and perfect settlement characteristics, they help in transferring a load of manufacturing to the soil.

Furthermore, these piles are reinforced piles made of concrete elements that are cast into the drilled holes. They aid in transferring the heavy load of building into the soil or the rock foundation on which the building is placed.


When used with low-vibrating continuous drilling method, these pipes are used for securing pits as well as for strengthening foundations. Means of adapted drilling tools do the execution of the soils using these pipes.

Why people choose Bored Piles:

  • They are affordable
  • Environmental friendly
  • They are ideal for the situations that have difficult soil conditions
  • They offer less noise and vibration

Other Pilling Techniques:

Some of the other types of piling technique apart from the Bored piling, which most piling experts use, are:

Screw Piling:

This kind of piling is used at commercial, residential, bridge, industrial and infrastructure construction.  It is quickest and strongest method in the market used for building a strong foundation. Unlike the traditional piling techniques that use helical and multi-fin cast helix, the new technique uses robust and strong single helix to have firm structural integrality.

Screw piles are used because these piles are capable of transferring the load via a shaft to the helix plate thereby making the base of the foundation stronger.  The size and thickness of the screw pile are designed as per the load and geometrical condition of the area.


It is used to support or retain the old structure or building that needs some uplifting. Underpinningis used at locations like warehouses, factories, commercial stores that need some extension. It is cost effective and commonly used in external areas.

CFA piling:

CFA piles or Continuous Flight Auger is a cast in-situ process which is used on soft grounds. This type of piling is used for grounds where deep casing or drilling is needed. The sides of CFA are supported by soil-filled auger thereby minimizing the need for bentonite slurry or temporary casting.

How are Boring Piles drilled?

The Boring is used to make any foundation solid and rigid by gauging on the condition of theground. While the equipment of boring comes in different sizes and shapes, the kind of bore a foundation need depends upon the manufacturing requirements.

Boring plies are usually drilled with circular augers. Once done, they are cleaned properly and are then filled with concrete and steel cages to strengthen the foundation. However, if the surface has soil or rocks, it is first removed by using drilling tools like soil augers, rock augers, core barrels and clean-out buckets. These tools are capable of boring up to 30m and range in diameter from 200mm OD to 1200mm OD.

The piling experts first check whether the ground has soft soil, stiff clay or have rock layer. They also measure the level of groundwater and other environmental constraints of the area.


Bored piling or bored piles are one of the most effective piling solutions where load cases are applied to large pile loads like uplift, tension, lateral load, or at places where heavy pile load is required.

Boring is usually done on the constructions that need a strong foundation. It is especially for tall building and bridge work. So, now you know the technology and mechanism behind it, call your construction agent and decide which technique would be the best for your foundation.
