Horizontal Directional DrillingHORIZONTAL DIRECTIONAL DRILLING · HDD
A trenchless technology for underground HDPE pipe installation without surface excavation, executed in three key stages: pilot hole drilling, reaming to the required diameter, then pipe pull-back through the hole — all monitored by a Sonde/Digi-Track radio guidance system ensuring real-time path accuracy. The safe and proven practice for HDD insertion of HDPE pipes.
- Stage 1 · Pilot Hole — precision drilling
- Stage 2 · Reaming — hole enlargement
- Stage 3 · Pull-Back — pipe installation
- Sonde / Digi-Track radio guidance system
- High-pressure Bentonite injection
- Road & facility crossing without service disruption
