Horizontal Auger Boring for Trenchless Utility Crossings Across the U.S.
Crigger Power uses horizontal auger boring to install casing pipe under roads, railways, and highways without disturbing the surface. This trenchless boring method is ideal for utility crossings where open excavation isn’t allowed or wouldn’t hold grade.
Our crews handle auger boring installation for sewer, water, and utility conduit across energy, telecom, and municipal projects. We drill directly through clay, sand, and mixed soils, maintaining line and grade with every push.
We don’t rent machines or hire third-party auger boring contractors. Every bore is handled in-house—with our own crew, our own gear, and field-tested control that keeps projects moving.
If your site needs trenchless utility boring with tight specs and minimal surface disruption, Crigger Power drills it clean and finishes it on schedule.
When to Use Auger Boring Instead of HDD
Auger boring is a trenchless method best used when accuracy in line and grade is critical, such asfor gravity-fed sewer mains or straight-shot utility crossings under roadways and rail lines. Unlike HDD, which excels at curved bores and deeper installs, horizontal auger boring uses a steel casing and cutting head to push a straight path forward with precise alignment.
Crigger Power uses auger boring on jobs where surface disruption needs to be low, but the bore path must be exact. It’s a proven method for municipal, industrial, and energy-sector work, especially in areas with shallow cover or where horizontal directional drilling could miss grade. Our crews bring their own equipment, plan every launch and exit pit in-house, and stay on-site until the last section of pipe is in place.
If the job calls for a straight, controlled bore through compacted ground, we’ll use auger boring to get it done right.
Auger & Boring Services for Utility Crossings & Infrastructure Installs
No two bores are the same. Every site presents different ground conditions, access challenges, and structural demands. Crigger Power adapts our trenchless boring methods to match the job, whether it’s pushing steel casing under a railway or cutting a precision grade through clay.
These services represent how we complete underground utility work where trenching isn’t an option.
Horizontal Auger Boring FAQs
Auger boring comes with its own set of questions—from how the method works to when it’s the right option over other trenchless techniques. Whether you’re a contractor, project manager, or utility planner, understanding the process can help you choose the right crew and avoid delays.
Below, our team answers common questions about horizontal auger boring and related trenchless boring services we provide across the country. If you don’t see your question, check out our Blogs and FAQs page for more information.
Horizontal auger boring is a trenchless pipe installation method used to push steel casing through soil while removing spoil with a rotating auger. It’s most commonly used under roads, rail lines, and embankments where open excavation isn’t allowed or safe.
Our crews set up on grade, install a casing pipe with hydraulic force, and extract soil through the casing using auger flights. It’s an efficient, clean process that keeps the surface intact and the bore accurate.
Choosing between auger boring and directional drilling depends on site access, bore length, and tolerance requirements. Auger boring is often preferred when:
- Line & Grade Tolerance: A straight, level path is required with no curve
- Short to Mid-Length Runs: HDD is more efficient for long distances
- Entry & Exit Restrictions: There’s no room for an HDD exit pit or tracking
- Steel Casing Required: For sewer or drainage pipe installations
In these cases, Crigger Power uses auger boring to maintain tight specs without needing high-entry angles or large clear zones.
Crigger Power typically performs auger bore pipe installation for casing diameters ranging from 8 inches to 60 inches. Run lengths vary by soil conditions and site layout but often range from 40 to 300 feet.
We match the bore to the utility, selecting the right auger boring machines, casing wall thickness, and spoil removal system. If your project has tight clearances or a short window, we can adjust to hit the mark fast.
Jack-and-bore is a type of auger boring service in which steel casing is pushed (jacked) through the soil while an auger removes the spoil. The two terms are often used interchangeably, but jack-and-bore generally refers to the full process of pipe installation under a roadway.
This method is ideal for sewer crossings, storm drains, or telecom conduit installs beneath hard barriers. Crigger Power handles jack and bore pipe installation projects nationwide with full crews and gear in-house.
Trenchless auger boring contractors typically work through cohesive soils, clay, silt, and soft rock. Auger boring is less effective in loose sand or highly mixed material unless reinforced casing or pilot tube boring is used.
Crigger Power assesses the soil before the first push, adjusting for moisture content, ground pressure, and stability. Our boring services are designed to adapt to changing conditions without sacrificing the grade or stalling the job.
Contact Crigger Power About Horizontal Auger Boring
Crigger Power takes on auger boring projects that most contractors won’t touch. We install casing beneath roadways, rail lines, and active sites using our gear and in-house crews—no waiting, no subcontracting.
If your project requires jack and bore installation, pilot tube boring, or trenchless utility crossings, we’ll review your plans, prep the setup, and keep the bore on grade from start to finish. Our team works clean, moves fast, and delivers without excuses.
