Horizontal Directional Drilling (HDD) is a trenchless method of installing underground pipelines, cables, or conduits in a curved or horizontal manner. It involves the use of a drilling rig, which drills a borehole underground at an angle, and then the drilling assembly is steered to achieve the desired horizontal direction. This method is commonly used to avoid surface disturbances, obstacles, or environmentally sensitive areas. Once the borehole is drilled, the pipeline or conduit is pulled th

Horizontal directional drilling (HDD) is a trenchless drilling method used to install underground pipelines, cables, and conduits without the need for traditional open-cut excavation. It involves drilling a borehole at a shallow angle beneath the ground's surface and then gradually curving the drill path to reach the desired location.
