There are various ways that trenchless tunneling is completed today. However, one of the most effective, and accurate is through the use of a guided boring machine (GBM). Guided boring is a highly accurate method for the installation of pipes, conduits and cables. A pilot bore is drilled using a rotating drill string and is then opened up to your required size for the product pipe by using a reamer. Guided boring is used in a range of trenchless techniques such as horizontal directional drilling (HDD) auger boring, and pipe ramming. During drilling when line and grade is crucial, the bit is laser guided allowing for a high degree of accuracy, often within 1 inch (or less) tolerances.
Barbco’s Pathfinder technology is a state of the art Guided Boring System. They have combined the proven technology of a pilot tube steering system with the dependability of a conventional auger boring machine to deliver accurate casing installations up to 60” diameter.
The Pathfinder Guided Boring System has hundreds of success stories since its birth in 2005.
