Directional Boring
What is Directional Boring?
Directional boring, commonly called horizontal directional drilling or HDD, is a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path by using a surface launched drilling rig, with minimal impact on the surrounding area.
Directional Boring, also known as Horizontal Directional Drilling (HDD) is the most efficient method known for installing utilities underground.
Directional boring eliminates the need for trenching or open cutting roadways and other hard surfaces, reducing interruption to traffic and disturbance to landscape as well as existing surfaces.
The trenchless drilling process is used for installing power and telecommunications cable conduits, water lines, sewer lines, gas lines, oil lines, irrigation lines, product pipelines and casings used for environmental remediation.
HDD is used to cross rivers, roadways, congested areas, environmentally sensitive areas and any area where other methods are more expensive or aren’t feasible. Use of the directional boring method is growing rapidly and is expected to increase for the foreseeable future.
Directional boring is used in place of other drilling techniques for the following reasons:
Deeper installation possible
Directional and curved capabilities
Less traffic disruption
Longer installation distances possible
Lower costs
No access pit required
Safer for the environment
Shorter project completion times

We utilize a technology called air/vacuum excavation to locate, expose and map facilities. Air/Vacuum technologies are employed to quickly and efficiently move soil from the test hole to holding tank on the truck.
Location & Surface Opening:
Utilities are designated and marked using highly specialized electromagnetic and radio frequency instruments. Once marked, a square opening is made just above the utility area.

Buried power lines and other facilities can be easily damaged and are dangerous to contact. Before you can safely cross or work close to an underground utility line with power digging equipment, you must see the lines with your own eyes.
Exposing or day-lighting: Existing buried utilities are uncovered via an air vacuum high pressure

Depth Measurement & Mapping: With the utilities exposed, facility depth can be verified, and mapping/surveying activities can be accurately performed.
