WHY CHOOSE HORIZONTAL DIRECTIONAL DRILLING?
Unlike traditional excavation techniques, directional drilling is a cost effective, environmentally-friendly, trenchless solution for a wide variety of underground installations.
Some benefits include:
Efficient installation times.
Greatly reduced requirements for permits.
Limited to no interruption to the general public. For example: road closures, flaggers, and traffic.
No disruption to the environment, existing infrastructure, utilities, or surface obstacles.
Small environmental footprint .
Possible Installations:
Utility Ducting
Electrical Cable
Fiber Optic
Tele-Communications
Solar/PV Cabling
Gas
Water
Pumped Sewer Lines
Drainage
Potential Job Sites:
Residential communities
Industrial and business complexes
Main roads and highways
Railroads
Rivers and other bodies of water
Airports
Municipal facilities
Stadiums
Golf courses
Farms
Wetlands
The horizontal directional drilling process has three distinct phases:
the pilot bore, expanding the pilot bore hole, and
pulling the desired product.
The pilot bore.
First, we complete the pilot bore using the drill bit and drill string to bore a small-diameter hole. A highly sophisticated locating system lets us track the progress of the drill bit at all times.
In almost all applications, a drilling fluid is required to help the drill bit cut through the different ground conditions encountered.
Expanding the pilot bore hole.
Secondly, after the pilot bore has been completed, the hole sometimes needs to be enlarged through a process called reaming. A specialized piece of tooling called a reamer expands the hole to a diameter that will fit the production pipe.
We may have to ream the hole several times depending on the final diameter of the pipe.
Pulling the desired product.
Lastly and most importantly, we pull the product through the hole with the drill rig.
