The CFA (Continuous Flight Auger) Drill Head is suitable for all kinds of applications: ground release drilling, dwell drilling, or pile
foundation drilling. The unit contains an injecting head used for the installation of CFA piles as well as part
and full displacement piles.
Difficult soil conditions can be made pilable by ground release drilling. This is the most economical and most
frequent practiced application in connection with piling and extracting works. High pressure swivels between auger
drive and auger head permit injecting of various medias for flushing purposes or concreting for CFA piles.
Our auger drives find a further use by wet and dry soil mixing procedures (WSM - Wet Speed-Mixing and DSM - Dry
Speed-Mixing). With single or twin auger drives single piles, groups or secant pile walls can be produced. The
existing soil material is mixed with a cement grout by WSM or with lime by DSM.
The Mobilram with CFA Drill head achieves high production rates with no excavation and operates as a noiseless
and vibration-free system.
