Bored pile is another type of reinforced concrete pile which is used to support high building which has a heavy vertical load. The bored pile is a cast-in-place concrete pile where the bored piles have to be cast on construction site, while other concrete piles like Spun Pile and Reinforced Concrete Square Pile are precast concrete pile which they’re cast in the factory.

Normally bored piling has been to carry on those tall buildings or massive industrial complexes, which require foundations which can bear a load of thousands of tons, most probably in unstable or difficult soil conditions. Bored piling is cast by using bored piling machine which has specially designed drilling tools, buckets, and grabs, it’s used to remove the soil and rock. Normally it can be drilling into the 50metres depth of soil. The advantage of bored piling is its’ drilling method, little vibration, and lower noise level.


The drilling method is depending on the condition of the soil, piling contractor has to do soil investigation and decide which drilling technology has to be carried on. Piling contractor decide the correct drilling technology and minimize disturbance of the surrounding soil. For cohesionless soils such as sands, gravels, silts etc, whether it’s under the water table or not, the pile borehole must be supported using steel casing or stabilizing muds such as bentonite suspension. After these, reinforcement bar will be put into the borehole and concrete will be poured into the borehole.

Bored piling is popular to be used in construction as a foundation especially for bridge work and tall building as well. Bored piling work has to be done by specialist bored piling contractor, normal piling contractor can’t be done without experience and knowledge about bored piles.
