2 x 7.5m Long x 600mm Diameter Continuous Flight Augers (CFA) + 1 x Bits all professionally newly hard faced & 1 x Column Holders
An Auger Cast Pile, often known as a continuous flight augering (CFA) pile, is formed by drilling into the ground with a hollow stemmed continuous flight auger to the required depth or degree of resistance. No casing is
required. A cement grout mix is then pumped down the stem of the auger. While the cement grout is pumped, the auger is slowly withdrawn, conveying the soil upward along the flights. A shaft of fluid cement grout is formed
to ground level. Reinforcement can be installed. Recent innovations in addition to stringent quality control allows reinforcing cages to be placed up to the full length of a pile when required. A typical reinforcing cage will
consist of 4 to 8 bars from #5 to #8 bars typically 1/3 the length of the pile with longitudinal circular ties spaced along the length of the cage. Where tension loads are present it is typical to see a single full length bar placed
at the center of each pile.
Auger Cast Piles cause minimal disturbance, and are often used for noise and environmentally sensitive sites.
