UNDERGROUND CONSTRUCTION & HDD
PLANNED FOR THE CONDITIONS.BUILT FOR THE APPLICATION.
Rock Ridge provides directional drilling and underground construction for telecommunications, electric, renewable energy, water, sewer, pipeline and large-scale infrastructure projects.
Our approach begins with the installation—not simply the drill.
Product size, bore profile, geology, depth, terrain, existing utilities and site conditions are evaluated to determine the appropriate construction method, equipment and support resources.
HORIZONTAL DIRECTIONAL DRILLING
Rock Ridge supports HDD installations from approximately 1 inch through 12 inches, with equipment selected around the requirements of each crossing.

Applications include:
- Fiber and communications conduit
- Electric and power conduit
- Renewable energy infrastructure
- Water and sewer
- Pipeline crossings
- Roadway crossings
- Utility crossings
- Campus and data-center infrastructure
- Rural and long-distance networks
BORE DESIGN & EQUIPMENT SELECTION
The equipment should fit the bore. The bore should not be forced to fit the equipment.
Rock Ridge does not define drilling capability by a single maximum bore distance.
Bore feasibility and equipment selection depend on the complete installation—including product diameter, geology, depth, terrain, alignment, existing utilities, access and other project-specific conditions.
Rock Ridge and its construction resources utilize Ditch Witch and Vermeer HDD platforms across multiple size and application classes.
Equipment ranges from compact drills designed for congested utility environments through approximately 30 × 40 class systems for larger installations and more demanding conditions.
Specific equipment is selected according to project requirements rather than applying a single drill configuration.
VIBRATORY PLOWING
Where soil conditions and system design allow, vibratory plowing provides an efficient method for long production routes.
Equipment resources include Ditch Witch and Vermeer vibratory plows, with heavier dozer-mounted plowing systems available when project conditions require them.
Applications include:
- Rural fiber
- Communications infrastructure
- Conduit
- Underground cable
- Renewable energy
- Long-route utility installations
ROCK & DIFFICULT GROUND
Difficult ground conditions require more than simply increasing machine size.
Rock Ridge can deploy construction methods and equipment for:
- DRILLING
- CUTTING
- HAMMERING
- TRENCHING
The appropriate method is selected based on geology, installation requirements, production objectives and site conditions.
EXCAVATION & TRENCHING
Supporting capabilities include:
- Mainline excavation
- Conduit installation
- Utility crossings
- Bore and receiving pits
- Handholes and vaults
- Utility exposure
- Tie-ins
- Site utility construction
- Restoration support
UTILITY EXPOSURE & DAMAGE PREVENTION
Existing utilities are treated as a construction constraint that must be understood before underground work proceeds.
Rock Ridge incorporates locate review, potholing, daylighting, crossing verification, bore planning and field documentation into the underground construction process.
PLAN IT. VERIFY IT. DOCUMENT IT. BUILD IT.
LET'S REVIEW THE ROUTE.
Every underground project presents a different combination of product, geology, utilities, terrain, access and production requirements.
Send us the route and project requirements. We'll evaluate the conditions and determine the construction approach and resources required to execute the work.
