The thrust boring method is generally used for single duct installs under road ways in un drillable ground (stoney). This technique involves two excavations where a mole shaped torpedo is lined up in the pit and hammers its way through from one pit to the other.
We can install up to a diameter of 110mm OD pipe right down to the smaller diameter of 20mm foot path crossings for installs of water pipe, telephone, power, gas and drainage.
This method can be used where access is an issue as minimal space is required.
Who are we
