CONTIGUOUS PILE WALLS

This non-waterproof form of site retention is constructed utilising cast-in-place piling techniques (typically CFA piles) to form a row of touching or closely spaced abutting piles. These piles are used for retaining adjacent structures and for lateral ground support to excavations, in ground conditions of all kinds, above the water table.

Pile diameters typically range from 400mm to 900mm and may be either in a cantilevered free standing, or anchored form. The use of reinforced concrete may offer a considerable economic saving over other forms of ground retention piling, particularly in circumstances where the piles can be incorporated as part of the permanent structure.

In situations where vibration or noise generated by driving piles is unacceptable, this form of retention piling has a distinct advantage.
