West Union Trenching
Iowa’s Trusted Specialist for Fiber and Power Infrastructure

West Union Trenching stands at the forefront of underground utility installation, delivering advanced fiber and power infrastructure solutions across Iowa, Minnesota, and Wisconsin. With more than three decades of experience, the company has become synonymous with reliability, innovation, and community-focused service.

Building and Protecting Underground Networks

Hidden beneath streets and cities, complex infrastructure networks power communities and industries. Modernizing and safeguarding these networks requires adaptability and expertise to navigate everything from rocky soil to tight urban grids. West Union Trenching partners with utilities to deliver end-to-end solutions that meet today’s infrastructure needs while preparing for tomorrow’s demands. The company specializes in cutting-edge directional boring technology to install fiber-to-the-home and underground power lines for both residential and commercial clients.

Founded by fourth-generation utility worker Erich Gamm, West Union Trenching has grown from a single-crew operation into a fully employee-owned, full-scale utility partner, covering projects from rural countryside to dense urban installations. Its state-of-the-art machinery lays the groundwork for subsurface optical fibers, cables, pipe conduits, and power lines. Advanced GIS mapping and GPS tracking technology are used to locate existing utilities and document new installations, minimizing disruptions while preserving space for future infrastructure.

Advanced Technology and Home-Grown Expertise

Speed and efficiency drive each installation project. From the earliest stages of network design and utility locating to construction, directional boring, ground splicing, testing, and final handoff, every step is managed in-house. Every project is digitally documented using an in-house GIS platform that integrates with GPS-enabled locating systems. Clients can review photos of splices and detailed mapping files remotely, gaining greater control and peace of mind through a mapped, traceable record that supports long-term utility management.

West Union Trenching’s expertise extends to specialized methods like rock drilling, sawing, and terrain-specific approaches. Whether installing cables and pipes with minimal environmental disturbance using advanced cable plows, maneuvering with hydraulic system-powered backhoes, or tackling excavation in residential areas and confined spaces with mini excavators, their team confidently handles even the most challenging projects. A wide range of machinery and skilled personnel trained in-house enable the company to complete projects on time and within budget, without depending on subcontractors.

Efficiency Found in Local Collaboration

Before a job begins, West Union Trenching’s intent is clear— minimizing environmental disturbance. Every project starts with diligent pre-construction coordination, whether in urban neighborhoods with tight spaces or rural areas with vast stretches and complex terrain. Clients value the consistency of a dedicated crew, with each project handled by the same foreman, supervisors, and team members. The team’s familiarity with the region’s terrain, utilities, and communities brings insight that outside engineers often miss, allowing for smarter route design and cost-effective solutions.

Strengthening Communities with Shared Ownership

West Union Trenching’s strong reputation is built on decades of experience and growth. The company’s story began in 1993, when Erich Gamm started installing cables at just 16 years old. By 18, Gamm had made significant investments in equipment to expand into larger construction and installation projects. Steady growth followed, driven by loyal employees. Today, West Union Trenching is a 100 percent employee-owned entity, with every crew member having a vested interest in the company’s success. The transition to employee ownership has fueled retention and fostered a sense of shared ownership while building deep community ties.

“We’ve always leaned on hard work and ingenuity in underground utility installation,” says Gamm, president. “But what keeps us moving forward is our ability to adapt through smarter equipment, better training and listening more closely to what communities need."

Building on a foundation of employee-centrism, West Union Trenching invests heavily in its people, including technical expertise and personality training for its foremen and other personnel. The intent is to help them better understand their coworkers and customers, strengthening collaboration and communication on projects. Open dialogues are maintained by asking the right questions to understand project needs and expectations, and identifying the tools or equipment that will improve service. This empowers the team to continually adapt and explore innovations in the utility industry, delivering solutions that exceed expectations.

Building Utility Networks for a Smarter Future

As demand for faster broadband and more resilient energy grows, the shift to underground infrastructure has become essential. West Union Trenching is expanding its capabilities to support data centers, AI-driven systems, and tomorrow’s complex power and fiber networks. Its expertise in underground infrastructure installation will play a critical role in meeting the accelerating demand for bandwidth and resilient utilities that fuel rapid technological growth. From first dig to final splice, West Union Trenching is building the connections that communities will rely on for decades to come.

The company brings together engineers and local utility partners to create custom plans, while locators mark existing infrastructure, verified by its crew through potholing. Directional boring is used to lay conduit with minimal surface disruption, followed by trenching and installing key structures like pedestals and transformers. Safety and precision are paramount, with equipment like hydro excavation tools, sewer inspection trucks, and GPS-tracked locators helping crews increase job accuracy and finish projects on time. Commitment to underground safety extends to disciplined use of the Iowa One Call system, ensuring accurate locating of underground lines and preventing costly strikes. The focus on safety and collaboration earned West Union Trenching Contractor of the Year by Iowa One Call and the state utility board.
