Driven piles are a quick and cost-efficient technique suitable for a variety of ground conditions. Soils are displaced rather than removed, resulting in zero spoil arisings.
Piles are constructed by driving a close ended tube, using a free-fall hammer into a dense ballast plug at the bottom of the casing. Additional casing is welded as required to achieve required depth. Once a designed set is achieved, piles are concreted and a reinforcement cage is inserted.
The steel cased bottom driven system is associated with low levels of noise and ground borne vibration. Piles of this nature are therefore well suited for use in close proximity to existing structures.
