Inside a Dudley's directional bore — drill head advancing through red clay

Directional
Boring

Horizontal directional drilling installs gas, water, sewer, power and fiber lines beneath streets, highways, streams and railroads without opening the surface.

Why trenchless

Less disruption,
cleaner results

Open trenching across a highway requires traffic control, detours and pavement restoration. A directional bore needs only an entry and exit pit, keeping roads open and surfaces intact while we guide the line precisely to its target.

Streets & highways — crossings beneath the traveled way with minimal encroachment.
Streams & waterways — no in-channel disturbance and simpler permitting.
Railroads — bored crossings built to railroad specifications.
Driveways & finished frontage — installations beneath concrete and landscaping without damage.

Paradise: 40 miles of underground fiber

The 2018 Camp Fire destroyed much of the infrastructure serving Paradise. Dudley’s crews have supported the AT&T fiber restoration since — installing 40 miles of underground fiber through red clay, rock cobble, and granite over a 6-year program.

How we bore

Our directional
drilling process

Every bore starts with planning. We locate and expose existing utilities by vacuum excavation, fuse the product pipe on site and install it in one continuous run.

Locate & expose — vacuum excavation confirms existing utilities before drilling.
Pilot bore — a guided drill head, tracked from the surface through clay, cobble and rock.
Ream & pull back — fused HDPE installed in a single continuous length.
Restore — pits backfilled, shoulders restored and disturbed areas hydroseeded.
