CHF - Macchine per CFA

Particularly suitable for urban interventions due to its quietness, cleanliness, and absence of vibrations, the continuous flight auger (CFA) technology is one of the most widespread methods for executing drilled and cast-in-place piles. The process is based on the use of hollow augers that are initially driven into the ground at a constant penetration speed. The auger is then slowly extracted while concrete is simultaneously pumped through the cavity of the continuous auger to create the pile.
