About Horizontal Directional Drilling (HDD)
Horizontal Directional Drilling (HDD) is a “trenchless technology” method of installing utilities and pipelines. HDD is ideal for crossing areas where open cut excavations are 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.
The depth and alignment the HDD drills are controlled by steering around structures and utilities. Upon completion of the pilot hole, the new pipeline is pulled back through the borehole. Pipes larger in diameter than the borehole are reamed out to a larger size prior to installing the pipe.
ECI’s Drills
Our drills are capable of installing steel, PVC, ductile iron, or HDPE pipe (up to 36 inch diameter). While most of our bores are in the 200 to 800 ft range, we have reached out as far as 2,700 feet in a single bore. Drilling depths of up to 80 feet or more are possible depending upon the total drilling distance. Our Ditch Witch 4020 and 100 All Terrain drills are specially equipped for efficient drilling and steering in rock conditions.
Our new Vermeer 330×500 maxi-drill provides a combined large diameter pipe with long distance capability using our 5 1/2″ drill pipe. We’ve paired this drill with a Tulsa Rig Iron MCS-1000 Portable Mud System and TT-660 Mud Pump. The 330×500 is capable of drilling a 36-inch-diameter pipeline over a distance of several thousand feet in soil or rock conditions.
All of our drills are equipped with the latest available location systems to guide and control the drill alignment.

Tooling and Other Equipment
ECI has a variety of specialty attachments for the HDD equipment, including a sensitive pitch sonde for gravity sewer installations; DigiTrak wireline system; Rail Head drilling bits with carbide teeth; steerable jetting assemblies for rock; and various types and sizes of back reaming tools for both soil and rock. In addition to tooling, ECI has a full complement of fusion equipment, pumps, pipe rollers, mud mixing equipment, mud reclaiming equipment, and a fleet of trucks to mobilize and support the work.
Horizontal Auger Boring
In addition to HDD, ECI is also capable of horizontal auger bores of up to 42-inch-diameter with our American Augers 42-600. This rig is typically used for shorter bores with steel casing and is launched from a jacking pit. We also have a 24/30-150 for smaller bores.
