Equipment set-up times are relatively short; subsequently it is possible to drill short distances economically. Most importantly borehole alignment does not necessarily have to be straight, because the technology makes it possible to change the borehole alignment and elevation to avoid intersecting existing utilities and other underground obstacles.
For installations at depths 3m or greater, horizontal directional drilling can even provide a cost-effective alternative to open-cut applications. Directional drilling is ideal for installing infrastructure beneath highways, roads, and railway tracks, without affecting traffic load on these networks. The technology can also be used for crossing of rivers, streams, lakes and buildings.
