Company HISTORY
HOW WE STARTED
United HDD Owners started in the directional drill field in the 1990s when horizontal directional drilling was still an emerging technology. Our founders saw the potential to transform how utilities cross roads, rivers, and sensitive terrain—without the disruption of open-cut excavation.
Over three decades we've grown from a regional contractor into one of the most trusted HDD specialists in the country, completing projects in 48 states for municipal utilities, pipeline operators, telecommunications carriers, and energy companies.
What hasn't changed is our core belief: every bore deserves the same level of engineering rigor, crew expertise, and safety discipline—whether it's a 200-foot fiber crossing or a 4,000-foot river bore under 80 feet of cover.
