Pilot Tube Auger Boring for Precision Utility Installation Nationwide
Pilot tube auger boring is our go-to method when jobs require exact line and grade. Crigger Power drills guided bores beneath roads, railways, and urban corridors—installing casing for sewer, water, and conduit without disturbing the surface.
This trenchless method combines laser-guided accuracy with pipe jacking force, allowing us to maintain tight tolerances through challenging ground. We drill through clay, sand, and fill while staying on target, even in shallow or congested areas.
We don’t subcontract or rent gear. Our team handles every pilot tube bore with in-house crews, our own guided boring equipment, and direct oversight from start to finish.
If your job requires accuracy, control, and clean results, Crigger Power delivers trenchless pipe installs without compromise.
How the Pilot Tube Method Works
Pilot tube auger boring combines guided boring accuracy with the power of traditional auger methods. The process begins with a small-diameter pilot tube that is steered along a precise line and grade using a theodolite or digital guidance system. Once the pilot path is established, a larger casing is pushed behind it while spoils are removed through the auger.
Crigger Power uses this trenchless method to install sewer mains, water lines, and utility sleeves with tight tolerances, especially where precision is non-negotiable. Our team handles every step in-house, from pilot steering to final pushback, without delays or third-party contractors.
If the job requires pinpoint accuracy beneath roads, railways, or developed zones, we use pilot tube boring to hit the target cleanly and keep your schedule intact.
Auger & Boring Services for Utility Crossings & Infrastructure Installs
Trenchless utility work demands accuracy, especially when installing infrastructure under roads, railways, or active sites. Crigger Power adjusts every bore method to fit the terrain, depth, and project constraints—no subcontractors, no delays.
These services reflect how we complete straight-shot utility crossings where trenching isn’t viable.
Pilot Tube Auger Boring FAQs
Pilot tube auger boring is one of the most accurate trenchless methods in today’s underground construction. But despite its precision, many clients still have questions about how it works, when to use it, and why it’s preferred over traditional bore methods. Whether you’re a municipal planner or utility contractor, understanding the process helps you bid smarter and plan better.
Below are answers to the most common questions we get about pilot tube auger boring, PTAB, and guided boring installations—including how Crigger Power controls line and grade, what makes this method so accurate, and how it fits into larger trenchless utility projects.
Pilot tube auger boring (PTAB) is a multi-phase trenchless method that uses a guided pilot tube system to establish a precise line and grade before enlarging the bore and installing casing. It’s ideal for utility installations that require strict alignment, such as gravity-fed sewer mains or pressurized water systems.
Crigger Power uses the pilot tube method to drill accurate bores in tight conditions, especially where traditional HDD or jack-and-bore methods would risk grade deviation. By combining real-time guidance with auger excavation, we deliver pinpoint accuracy with zero surface disruption.
While both methods install casing pipe underground, guided boring provides superior control over the bore path and grade. It’s the right choice when vertical accuracy matters, such as for sewer, stormwater, and other gravity-fed systems.
We typically recommend guided boring when the jobsite has strict tolerances, shallow cover, or limited surface access. If exact line and grade are required, Crigger Power’s PTAB crews keep the bore path clean, controlled, and on-spec from launch pit to exit.
Pilot tube boring offers some of the most precise results in the trenchless industry. Using a guided head and digital tracking system, our crews can maintain tolerances within fractions of an inch across long distances.
This level of accuracy is critical for public works, sewer installations, and utility corridors where even slight deflection can compromise pipe flow or alignment. Crigger Power’s field-tested approach means that every section of pipe follows the planned route without drift, deformation, or grade loss.
Pilot tube auger boring is best suited for municipal sewer and water projects, utility crossings under roads or railways, and sites where surface disruption must be minimized. It’s especially useful in urban or industrial areas where excavation would interfere with traffic or infrastructure.
Crigger Power uses PTAB across energy, telecom, and public sector jobs, especially when access is limited or the bore must be flawless. We adapt the approach to match site conditions and stay on grade without delays or third-party handoffs.
PTAB performs best in stable, displaceable soils like clay, loam, and fine sand. While it’s not designed for hard rock or cobble, Crigger Power evaluates every site ahead of time to confirm suitability or pivot to another trenchless method when needed.
Our crews bring multiple boring solutions to the table. If pilot tube trenchless technology is right for the job, we’ll drill it clean. If the soil shifts mid-bore or becomes unstable, we adapt on the fly using field-proven techniques and backup equipment.
