Because the soil-filled auger supports the hole while it is drilled, CFA piling needs no casing or drilling fluid, which makes it fast and quiet. Concrete pressure and volume are monitored throughout the withdrawal.
CFA is suited to moderate diameters and depths; very large or deep piles, or hard rock, usually call for bored piles instead.
How Civova handles it
Civova records CFA piles alongside bored piles (type, depth, diameter, concrete and rig), so every pile on a project is costed the same way.
