HDD – Horizontal Directional Drilling

HDD – Horizontal Directional Drilling

Horizontal directional drilling installs pipe and conduit along a designed curve between an entry and an exit point, without opening the ground in between. Where a crossing would otherwise mean closing a highway, disturbing a river bed or excavating through an established neighbourhood, HDD removes the surface disruption entirely — and with it most of the permitting, restoration and community impact that the open cut would have carried.

The method is precise but unforgiving of poor planning. Success is determined before the rig starts: by the geotechnical investigation that establishes what the bore will actually pass through, by a bore path designed within the pipe's allowable bend radius, and by a drilling fluid programme matched to the ground conditions. We treat all three as engineering deliverables rather than field decisions.

Our rigs cover everything from short utility crossings to long river and highway installations, with steering tracked continuously against the design profile so deviation is corrected while correction is still straightforward.
