Winter is here, and even though temperatures and snow can be a nuisance, we still find opportune days that allow us to complete our utility installation projects. We are currently working on irrigation projects for our golf course customers, drainage solutions for HOA's, and multiple other jobs placing fiber optic and electrical conduits for customers in Wyoming and Colorado.
We're here to help. Get in touch with us for HDD or trenching services at https://www.lmunderground.com/

We're so excited about the future of electric vehicles, and how could we not be? Fresh air and blue skies courtesy of environmentally friendly charging stations. L&M has provided directional boring for multiple customers who are installing EV charging stations across the state. Directional boring is the cleanest way to get electrical conduits to these new stations. A special thanks to our crews who make bore pits as clean as our air!
