Horizontal Directional Drilling Stotts Construction Co. Columbia, KY
Horizontal Directional Drilling is a guided trenchless method in which a pilot borehole is drilled along a pre-determined bore path, subsequent hole enlargement follows the path set by the pilot bore, from the surface with minimum disturbance. Short, medium and long lengths of pipe can be installed without intermediate pits.

All About Horizontal Directional Drilling JB Trenchless
Horizontal directional drilling (HDD) consists of several installation steps. First, a pilot bore is made with a suitably sized drilling rig. The bore is steered to create an initial hole at the required line and grade. Successive reamers are then pulled back to enlarge the bore diameter to the desired size.
Horizontal Directional Drilling What Makes this Technique Useful
What is Horizontal Directional Drilling? Traditional open cut pipeline installation (digging a trench and laying the pipe in it) can be very challenging when a pipeline must cross under obstacles. Instead of a surface trench, the HDD approach involves drilling a horizontal hole beneath obstacles and pulling the pipeline through the hole.
