Steel Casing Boring is a trenchless method used to install protective steel casings under highways, railroads, airports, and other critical infrastructure. The casing acts as a durable sleeve, housing water mains, sewer lines, gas pipelines, power conduits, and telecom lines while ensuring compliance with DOT and railroad regulations.
At Trinity Boring Solutions, we specialize in safe, precise Steel Casing Boring using auger boring machines, jack-and-bore techniques, and engineered jacking pits. From small-diameter utility crossings to large municipal and industrial installations, we deliver efficient casing bores backed by QA/QC documentation.

What Is Steel Casing Boring?
Steel Casing Boring is the process of installing steel casing pipe underground without open-cut trenching. The casing is pushed or auger-bored through the soil, while spoils are removed using augers. Once installed, utilities are pulled or pushed inside the casing for long-term protection.
This method is required by DOTs, railroads, and airports whenever utilities cross under major transportation corridors. It ensures that if utilities ever need replacement or repair, crews can work inside the casing without disturbing the roadway or rail line above.

The Steel Casing Boring Process (Step by Step)
Site Preparation & Bore Pits
Entry and exit pits are excavated, shored with trench boxes or sheet piling, and prepared for auger boring equipment.
Equipment Setup
Auger boring machine or jacking frame is aligned with the bore path.
Casing Installation
Steel casing segments are welded together, pushed through the soil, and spoil is removed via augers or conveyors.

Utility Placement
Once casing installation is complete, product pipes or conduits are placed inside the sleeve.
QA/QC & Documentation
Final alignment, weld inspections, and as-built reporting provided.
