HDD Rock Drilling


Our years of experience and range of specialised equipment allows us to install pipelines in the toughest ground conditions and we have completed numerous difficult rock crossings.

We design, build and operate a versatile range of Rock Drilling equipment including maxi to mini drill rigs with pullback forces from 14te up to 300te. Our systems work from the surface with no need for deep excavations and allow pipes to be installed either straight or curved to steer clear of obstacles.
