Traditional methods to expanding utility infrastructure revolve around open trench construction. These methods are in reality far more expensive than they initially seem. The cost of remedial work such as the restoration of roadways, sidewalks, landscaping, etc., in addition to the concerns of traffic management and the risks involved in open trench construction, make open trench a far less desirable construction method than it would otherwise seem.
Horizontal Directional Drilling solves these problems with a safe and environmentally responsible alternative.

How It Work
Horizontal Directional Drilling (HDD) is a three-part process. First, a pilot hole is bored by means of the drill pushing the sonde (a transmitter located at the head of the drill string) into the ground toward the desired location. A locator positioned above the surface tracks the movement of the sonde and relays instructions to the drill operator via radio. Once a pilot hole has been bored, and the drill head has been brought to the surface at the exit pit, the second process, known as reaming and pull back, is conducted.
In the second stage, a reamer is attached to the front of the drill string and the drill operator begins the pull back and rotation. The rotation allows the reamer to expand the hole to the necessary width for the product installation. After pull back has been completed, the third process known as restoration can begin.
In this last process, any drilling fluid from catch pits is removed from the site and disposed of safely. Entry and exit pits are restored to their original condition. All equipment and obstructions are removed from the location, leaving the site in its original state with minimal impact.
Due to the simplicity and effectiveness of HDD, it is the preferred choice of underground utility construction and is one of the fastest growing technologies in the trenchless industry.
