On this project, we were tasked with diverting a 219mmOD Gas pipeline under the River Eden and West Coast Mainline railway – drilling 640m through hard Permain Penrith Sandstone.

The strength of the Sandstone and ground conditions presented challenges for our team, with the heavily fractured rock resulting in a loss of returns during piloting. We overcame these by installing a steel sleeve over our entry drill and grouting sections of the bore using our specialist HDD Rock Drilling equipment.
