Pilot Boring

High-accuracy trenchless boring with quarter-inch tolerance up to
400 feet. Ideal for sewer, water, and utility installations where precision line and grade are critical.

- Overview

What Is Pilot Boring?

Pilot boring is a trenchless installation method that uses a steerable boring head guided by a locating system to achieve extremely precise line and grade. Unlike conventional boring, the operator can make real-time steering corrections throughout the bore — delivering accuracy within a quarter inch over distances up to 400 feet.

JAG Enterprises uses pilot boring for projects where grade is critical — sewer lines, gravity-fed water lines, and utility conduits that must meet strict engineering tolerances. Our crews operate throughout Idaho, Montana, Nevada, Utah, and Wyoming.

- How It Works

Pit Preparation

Entry and exit pits are excavated at each end of the bore path. These are the only areas of surface disruption throughout the entire project.

Pilot Bore

A steerable boring head is launched from the entry pit. An operator uses a locating system above ground to monitor and guide the bore head in real time, making corrections to stay precisely on line and grade.

Accuracy Verification

Once the pilot bore reaches the exit pit the line and grade are verified against engineering specs before any pipe is pulled back.

Pipe Installation

The carrier pipe — sewer, water, conduit, or casing — is attached and pulled back through the bored path. The pits are then backfilled and the surface restored.
