A concrete pile is a component in a pile foundation which is driven or cast into the ground to ensure that a foundation is deep enough to distribute the weight of a finished structure safely. Cast in situ piles (bored piles) provide a versatile alternative to driven piles. The drilling method allows excavation in a wide variety of soil conditions, dry or water logged and can also penetrate through low capacity, soft rock formations.
As no shocks or vibration are induced the bored piling system is the most widely used in town centers or congested sites. Concrete of a specific mix design is placed into the pile using a concrete pump. The auger is withdrawn from the bore as the concrete fills the drilled hole behind it leaving a concrete pile up to 35 meters deep.
