The Method

Mini HDD (or Mini horizontal directional drilling) is a guided trenchless method in which a pilot borehole is drilled along a pre-determined bore path, subsequent hole enlargement follows the path set by the pilot bore, from a pit or from the surface with minimum disturbance.

  • Pipes are installed straight or curved to steer clear of obstacles and existing services.
