Earth Pressure Balance Machine (EPBM) tunneling utilizes a Tunnel Boring Machine (TBM) that allows for installations in unstable ground. The ground at the cutting face is supported by ‘earth pressure’ by balancing the advancement of the tunnel with the discharge rate of the excavated soil that is contained through a screw auger.

The EPBM monitors targeting data, pressures, position, speed, torque and flow in order for the operator to accurately achieve maximum productivity. Because of its unique advantages, this System allows our expert operators to tunnel soft, wet and other unstable ground conditions with speed and safety not usually possible.
