For jobs where surface obstacles and the cost of restoration are issues, trenchless construction provides an efficient alternative to conventional trenching. Most cable and pipe can be installed with directional drilling technology including underground power lines, communications cables, pipe for natural gas, and water and sewer lines to name a few.

How it works:

No starting pits are needed; bores are launched from the surface and proceed downward at an angle until the necessary depth is reached. Then the path of the bore is leveled, and the bore head is steered to a designated exit point where it is brought to the surface.

As the bore progresses, lengths of drill pipe are added. When the initial bore is complete, material to be installed is attached to the drill string, often with a back reamer to enlarge the diameter of the bore hole, and the installation is made by pulling the product back through the bore hole, removing drill pipe sections as the drill string approaches the drill frame. Drilling fluid is used in making the initial bore and during pull back.

Directional drilling equipment goes under:

• Busy streets
• Highways
• Freeways
• Sidewalks
• Expensive landscaping
• Driveways
• Parking lots
• Runways
• Existing utilities

Advantages:

• Minimal surface damage
• Minimal interruption of vehicular traffic
• Minimal interruption of pedestrian traffic
• Reduced restoration, time, and cost
• Reduced inconvenience
