L & M Underground, Inc.

We provide horizontal directional boring to install all types of utilities including water, sewer, electric, gas and fiber optic.  Our fleet of drills range in sizes from small drills for residential bores to larger drills with rock capabilities for highway and mountain projects. We can place multiple pipes in one bore hole or single pipes up to approx 36 inches diameter depending on conditions. We do not perform vertical well drilling, pipe bursting or auger boring.

We provide and install commercial EV Charging stations in new construction and existing parking lots.

In addition to vacuum potholing for subsurface investigations to verify depths of existing utilities, we also perform hydro-vac slit trenches and pits and other hydro-excavation as needed to protect existing utilities. We own a fleet of 500-800 trailer vacs.  For larger projects we rent vac trucks on weekly and monthly basis as needed.

HDPE fusion may be performed on site by our crews or by factory certified fusion techs provided by our supplier partners.

We install underground utilities of all types including gas, electric, water, sewer, and fiber utilizing directional boring, trenching and plow methods. We place utilities in right of ways, highways and new neighborhood developments.  However, we generally do not bid to GCs on site utilities for ground up new builds as we are more suited to work directly with the individual trades (i.e. plumbing, electrical contractors that require boring for their connections)

We have worked on a number of CDOT projects placing fiber and electric along I-70 and I-25 utilizing both horizontal directional boring and trenching.  We are certified SBE for CDOT, prequalififed for projects up to $5,000,000 and have experience with the certified payrolls and LCP tracker.

The types of conduits we commonly install with HDD include HDPE, Certa-Lok, Fusable PVC, and TR-Flex ductile Iron.

We also provide open trench installation of conduits and have experience with installing spacers, and providing concrete cap as needed.

We perform all forms of outside plant construction including conduits,  setting of utility vaults, handholes, transformer pads, and fiber placement.

We utilize pneumatic missiles for small bores where set up space does not accommodate a horizontal directional drill.  A missile bore requires a small excavated pit on each side of the bore approximately 2' wide, 4' long and as deep as the bore is planned. The missile is placed in one pit and pushed through the ground using a compressor.
