Before sheet piles can be installed, an ADU 1500
loosens ground consisting of sand, gravel, clay and small boulders with an auger and pilot bit designed for use in rock. Loosening the ground prior to installation, reduced vibration levels that could have damaged buildings located nearby.
Length of auger: 9 m (one piece)
Auger diameter: 500 mm
Pilot bit type: SFBC R3HD
Drilling speed: 1.2 – 1.5 m/min
