H.L. Chapman has averaged over 1,000 MILES per year of underground trenching allowing oil & gas infrastructure to expand across areas of need for over 45 years. Our machines ditch dirt faster than excavators and can remove rock significantly cheaper than blasting. With own haul trucks, mechanic trucks, welding, fueling and support services, we provide turnkey trenching operations that accelerate your schedule and save you money overall.
