JAM Underground
Utilities LLPMinnesota Underground Utility Contractor
We provide professional underground drilling, trenching, utility bores, horizontal directional drilling, conduit installation, main line construction, and underground utility support for telecommunications and infrastructure projects.
A dependable underground utility partner for demanding infrastructure work.
JAM Underground Utilities LLP is a professional underground utility subcontractor headquartered in Minnesota. We support telecommunications carriers, utility companies, and civil infrastructure contractors with skilled field operations and reliable project execution.
We built the company around a simple idea: crews that show up, deliver safe quality work, and leave the site ready for the next phase. That mindset drives every bore, every trench, and every conduit run we install.
Deliver safe, dependable underground utility construction that our partners can build on.
We are committed to safety, quality, and integrity in every phase of field operations — protecting our people, respecting our customers' schedules, and building long-term relationships through consistent, honest work.
