Horizontal Directional Drilling (HDD) is a trenchless methodology that provides an installation alternative that can offer a number of benefits over traditional open-cut. It is used instead of other techniques to provide less traffic disruption, lower cost, deeper and/or longer installation, no access pit, shorter completion times, directional capabilities, and environmental safety.HDD can be implemented with very little disruption to surface activities, requires less working space, and may be performed more quickly than open-cut methods. HDD is used for installing various types of infrastructure: 

  • Product Pipelines
  • Telecommunications
  • Power cable conduit
  • Oil lines
  • Gas lines
  • Water lines
  • Environmental remedication casings

Horizontal directional drilling is done with the help of a viscous fluid known as drilling fluid. It is a mixture of water and, usually, bentonite or polymer  continuously pumped to the cutting head or drill bit to facilitate the removal of cuttings, stabilize the bore hole, cool the cutting head, and lubricate the passage of the product pipe.
