Augercast Pile

Augercast pile An augercast 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 While the cement grout is pumped, the auger is slowly withdrawn, conveying the soil upward along the flights.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

Auger Cast Piles

Auger cast piles are installed by rotating a continuously flighted hollow shaft auger into the soil to a specified depth. High strength cement grout is pumped under pressure through the shaft as the auger is slowly withdrawn. Reinforcing steel is added per pile specifications. An auger cast pile is both end-bearing and friction-based. Pile diameters of 12” to 18” are typical, but larger piles are available.
