Frequently Asked Questions (FAQ)

Q: What is directional drilling, and how does it work?

A: Directional drilling, also known as horizontal directional drilling (HDD), is a trenchless method for installing underground pipelines, conduits, and cables. It involves drilling a pilot hole along a pre-determined path, followed by reaming to enlarge the hole, and finally, pulling the pipe or conduit through the expanded bore. The process minimizes surface disruption compared to traditional trenching.
