C.F.A. (Continuous Flight Augers)

Large-diameter CFA piles are widely used in low-density soils. CFA piles make it possible to avoid soil decompression and the use of bentonite slurry during drilling, greatly simplifying the disposal of debris.

WORKING PHASES

1. Drilling the pile;
2. Extraction of the auger while concrete is simultaneously pumped through its hollow stem;
3. Placement of the reinforcement;
4. Load testing.

TECHNICAL DATA

• Pile diameter: 400 to 1000 mm
• Depth: 25 ≈ m
