Front of Wall (FOW) method
Special dual-head drilling drives permit simultaneous drilling in of the auger and the piping. The advantage lies in low-noise and low-vibration work, for example directly on foundations of existing buildings. This process is called Front of Wall (FOW) method. Another auger drilling process is the CFA method.
