In most cases a secant pile wall is installed with the resonance-free VDW (in front of the wall) procedure and serving at the same time as foundation for the building. Typical areas of application are underground parking, rain water retention basins and so on.

Beside secant pile walls also contiguous and tangential pile walls or single piles can be installed. Onto the VDW double auger head system a casing as well as a drilling head is attached. The tools are turning in opposite directions and the position of the auger head can be adjusted depending upon soil conditions. While pulling the tools concrete is pumped into the bore hole. Furthermore double auger heads serve as a tool for soil exchange procedures and full displacement piles.
