HORIZONTAL DIRECTIONAL DRILLING
Introduction
Horizontal Directional Drilling is a trench less methodology providing an installation alternative that can offer a number of benefits over traditional open cut.
HDD can be implemented with very little disruption to surface activities, requires less working space, and may be performed more quickly than open cut methods.
Although there are currently no national standards regarding HDD installations activity, HDD pipeline installations are becoming really common and may be the fastest growing trenches construction method to day. They can be used to install new pipelines or replace existing ones.
