Tunnelling includes a set of specialised drilling and ground reinforcement techniques used to ensure stability and safety during underground excavation.
These solutions are applied to support tunnel faces, reinforce the surrounding ground and control deformation in weak or fractured rock and soil.
Typical applications include rock bolts and forepoles, which are essential during sequential excavation methods.
Tunnelling technologies enable precise installation with low vibration, reduced disturbance and high operational safety, even in complex geological conditions or confined underground environments.
