The purpose of pile foundations is to transfer the weight of a structure to the bearing ground which is located beneath the surface. The key components of pile foundations are the piles themselves and the pile caps which are connected when the piles are driven into the ground.

There are several factors which need to be considered when choosing the method of pile installation in order to avoid causing any damage to the piles. The size and weight of the pile, the resistance that occurs when driving the pile, the amount of space and headroom on the site, access to cranes and any possible noise restrictions all need to be taken into account.

Pile driving methods can be split into two categories; displacement piles and non-displacement piles. Displacement piles can be driven using dropping weight, explosion, vibration, jacking (micro piling only) or jetting. Non displacement pile methods are continuous flight auger (CFA), underreaming and C.H.D.P.
