Retaining walls and cofferdams are the main applications for sheet piling. Continuous Flight Auger Piling generally being ideal for environmental and noise sensitive sites. These types of piles are for both load bearing piles and excavation support. (Can otherwise be known as Auger Cast Piles.)
No casing is required, for a hollow stemmed continuous flight auger is rotated into the ground to the required depth or degree of resistance. A high slump concrete mix is then poured or pumped down the stem of the auger. While the concrete is pumped, the auger is slowly withdrawn. A shaft of fluid concrete is formed to ground level.
