Horizontal directional drilling, also known as HDD, is a trenchless method of installing underground pipelines and cables. The method involves drilling a pilot hole from the surface in the direction of the target, then reaming the hole to the required size and pulling the pipe or cable through. This method offers numerous benefits over traditional trench excavation, including reduced impact on the environment and surface features, lower costs, and reduced disruption to communities and businesses. With the increasing demand for underground infrastructure, HDD is becoming a popular choice for pipeline and cable installations.
