Horizontal Directional Drilling

September 28, 2010

Horizontal Directional Drilling is a trenchless technique of installing underground pipes and conduits that is gaining
in popularity. Besides enabling crossings underneath rivers, roads and structures where open trench techniques
would be impossible, HDD technology can help avoiding soil disturbance and the costs associated with an
excavated trench. Horizontal Directional Drilling can accomodate any size pipe or conduit.
