About Moreno Trenching

Over the past 32 years Moreno trenching has become synonymous with dry utility construction in Northern California. Originally as a subcontractor to PG&E, our company took off with the advent of applicant (developer) installed dry utility contracts to become one of Northern California’s largest and most respected dry utility contractors.

We have continued to grow our services to where we can now offer our clients not only joint trench installations; but also our most recently added services, electric, gas and composite engineering and design services.

Our ability to provide these services put all your project ancillary functions in the hands of one contractor, saving you time on your project schedule and in your back office.

We believe the ability to provide a turnkey joint trench project to our developer clients gives them the best opportunity to have a quality installation in the shortest time possible eliminating a number of co-ordinance points between subcontractors working for you.

We call it hassle free joint trench and it is what we pride ourselves on providing. We would be very happy to add you to our list of satisfied customers.

I have worked with Moreno Trenching for well over 10 years and they have always been an excellent subcontractor. They are customer oriented and have great relationships with the utility companies all over Northern California. They have the capacity to man the job and complete it with a minimum of headache to other owner or general.
