North Carolina Directional Drilling - Auger Boring Contractors

Auger boring is a trenchless construction method used to install underground pipelines, conduits, or cables. It involves a rotating cutting head mounted on a casing or pipe, which is driven horizontally through the ground by a powerful boring machine. As the cutting head advances, an auger (a spiral-shaped drill) inside the casing removes soil or other materials, transporting them back to the machine.

This method is commonly used for installing utilities under roads, railways, or other structures without disrupting surface activities. Auger boring is ideal for stable soil conditions and is widely used in the construction and utility industries due to its cost-effectiveness and precision.

Auger boring is a versatile trenchless method used across various applications due to its ability to install pipelines and conduits with minimal surface disruption. Here’s how it applies to each area:

Jack and Bore

• Auger boring is often referred to as “jack and bore” in the industry. It uses hydraulic jacks to push steel casings into the ground while the auger inside removes soil. This technique is ideal for crossing beneath obstacles like roads or railways without open trenching.

Horizontal Auger Boring

• Horizontal auger boring is the process where a rotating auger within a steel casing removes soil during horizontal drilling. It’s typically used to install pipelines, conduits, or cables along a fixed path beneath surface obstructions.

Trenchless

• As a trenchless construction method, auger boring minimizes surface disruption and excavation, making it an environmentally friendly and cost-effective solution for underground installations.

Oil & Gas

• In the oil and gas sector, auger boring is used for installing casings, pipelines, or conduits under existing infrastructure such as roads or railways. It’s commonly employed for midsized installations that require precise alignment.

Sewer

• Auger boring is effective for sewer installations that demand precision. The technique allows for gravity flow pipelines to be installed “on grade” (with a specific slope), ensuring proper wastewater drainage.

Drainage and Stormwater

• It is widely used for installing stormwater and drainage systems, especially where the pipes need to align with specific gradients for gravity flow. Auger boring ensures accurate placement and minimizes disruption to surrounding areas.

On Line and On Grade

• Auger boring is valued for its precision. “On line” refers to maintaining a consistent horizontal alignment, while “on grade” involves installing pipes with a specific slope or gradient. This is critical for gravity-driven systems like sewers and drainage pipelines.

Gravity and % Fall

• Gravity systems, such as sewers and stormwater drains, require precise grading or “fall” (expressed as a percentage). Auger boring allows for accurate installations to meet design specifications, ensuring proper flow.

Roads and Railroads

• Auger boring is ideal for crossing beneath roads and railways without disrupting traffic or operations. It’s a preferred method for installing utility lines under these critical infrastructures.

Municipal

• Municipal projects frequently use auger boring to install water, sewer, and utility lines beneath public roads and spaces. The trenchless nature reduces costs and minimizes inconvenience for the community.

Government

• Government-funded infrastructure projects often rely on auger boring to install pipelines and conduits efficiently and with minimal environmental impact. This method aligns with public works goals of cost-effectiveness and reducing surface disruptions.
