![]() ![]() Reaming is done, if necessary, to upsize the hole. HDD is ideal for crossing areas where open cut. The pipe or cable is then installed by using the drill string to pull it through the excavated route back to the start point. Horizontal Directional Drilling (HDD) is a trenchless technology method of installing utilities and pipelines. These general contractors typically have a larger project but need HDD services for certain utilities. We own and operate the most technologically-advanced directional drilling equipment, with pullback forces ranging from 14te up to 300te, and with over 40 years of experience are able to complete small, medium and major pipeline projects throughout the UK and Ireland. Directional drilling is the process of drilling a pilot hole along a planned route between two predetermined points. With this method, we can install pipelines of almost any material, with diameters ranging from 25mmØ – 1,200mmØ in distances from 15m – 1,500m installed in one single operation. ![]() It will reduce those costs enabling total project costs to be more feasible. As with most trenching operations the impact on local surroundings can be massive and extremely unpleasing whilst also bringing very high installation costs. This prevents the need for costly and inefficient trenching methods which are harmful to the environment and create massive amounts of waste materials. Horizontal Directional Drilling (HDD) causes no disruption to roads or rail, does not scar the landscape and works from the surface, meaning this trenchless method is suitable for environmentally sensitive areas. Connecticut Directional Drilling Here at Directional Technologies, Inc, we specialize in utility directional drilling projects. Horizontal Directional Drilling (HDD) or Horizontal boring as it sometimes known, provides a safe and cost effective solution for the installation of pipes, ducts and cables where conventional open cut methods are not permitted, practical or viable.
