Horizontal Directional Drilling (HDD)
Horizontal Directional Drilling (HDD)
Horizontal Directional Drilling is a method of drilling used for laying subsurface pipes and cables without interfering with infrastructure (streets or railways) or harming the environment (e.g. rivers and lakes).
The first step in HDD-Drilling is a controlled pilot hole. Where necessary a reamer is then used for widening the borehole. Finally the cable or pipe is pulled through.
All three steps need an appropriate drilling fluid in order to proceed successfully.
Functions of the HDD fluid:
- Minimizing of sedimentation and friction
- Effective transportation of excavated soil
- Easy recycling of suspension
