Service overview
What HDD Work involves
Horizontal Directional Drilling (HDD) allows pipelines or ducts to cross obstacles without opening the surface throughout the crossing. A pilot bore is drilled along the engineered path, enlarged in stages and prepared for controlled pullback of the pipe string.
How we support the work
Our site team coordinates manpower, operators, access and equipment around the approved client scope. Execution is sequenced so each work front is ready for the next pipeline activity with minimal avoidable delay.
