Horizontal Directional Drilling (HDD)
HDD is a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area. Directional boring is used when trenching or excavating is not practical. It is suitable for a variety of soil conditions and jobs including road, landscape and river crossings. Pipes can be made of materials such as PVC, polyethylene, polypropylene, Ductile Iron, and Steel if the pipes can be pulled through the drilled hole.
Utilizing this method of utility installation provides less traffic disruption, lower cost, deeper and/or longer installation, no access pits, shorter completion times, directional capabilities and environmental safety. The technique has extensive use in urban areas for developing subsurface utilities as it helps in avoiding extensive open cut trenches.
