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.
