Directional drilling is a "trenchless technology" method of installing utility lines. The depth and alignment of the drill is controlled to allow steering around other known structures and utilities. Directional drilling is ideal for crossing areas where open cut excavation is not allowed, such as railroads, highways, rivers and streams, airport runways, and wetlands. It is also appropriate for busy streets, narrow corridors, and deep alignments where standard trenching would be cost prohibitive.

Our drills are capable of installing steel or HDPE pipe (up to 24 inch diameter) over a distance of up to 1200 feet or more. Drilling depths of up to 50 feet are possible depending upon the total drilling distance.

Our American Augers DD-10 has a torque of 15,000 foot-pounds and pull-back force of 95,000 pounds to handle a variety of soil conditions including rock. All of our drills are equipped with the latest available location system to guide and control the drill alignment.

ECI has a variety of specialty attachments for the directional drilling equipment, including a sensitive pitch sonde for gravity sewer installations; Rail Head drilling bits with carbide teeth, and various types and sizes of back reaming tools.
