What is Horizontal Directional Drilling

Horizontal Directional Drilling or HDD is an innovative procedure used for the installation of underground cables, pipelines as well as service conduit using trenchless methods. It revolves around using highly sophisticated directional drilling machinery, along with associated attachments, that help in drilling along the selected bore path as well as back reaming the needed pipe. 

The directional drilling machinery helps in the boring of the pilot hole, and consecutively many large-sized reamed holes, to pull out dirt as well as rock cuttings using drilling mud. 

The Need for Horizontal Directional Drilling

  • The process helps in getting utilities from a specific point to another, without causing any destruction of the existing obstacles or grounds. 


  • The method is much different from the traditional trenching procedure, as it helps to connect utilities as well as services in areas where trenching is difficult to carry out. 


  •     HDD drilling is primarily utilized for building crossing under roads, rivers, as well as existing structures, to install conduits and pipes for the transportation of different materials and fluids. 


  • The cost of construction, as well as restoration of wastewater pipes and new water pipes using the HDD method, is less expensive.
