  • How does horizontal directional drilling work?

    Pilot hole directional drilling is a process whereby a drill machine on an incline ramp bores a hole into the ground on a significant angle. This means a tunnel is created which covers great horizontal distance without the need for underground manual work. The general process is split into three parts:


    1. Pilot Hole – drilling a small diameter pilot hole along the designated path using a steerable drill stem
    2. Prereaming – increasing the bore diameter into the size needed for the installation of the utility
    3. Pullback – the drill cord is used to pull the pipeline or cable through the enlarged hole
  • What equipment do you use for directional drilling?

    Our main machine is a Vermeer D24x40 directional drill, but we also have an all-terrain Ditch Witch JT3020. Please view our Equipment page for more information.
