Gippsland Premier Trenching & Drilling Experts
About Us
Family-Owned. Gippsland-Focused. Decades of Trusted Work.
Built from the Ground Up
Founded in 1990 by Colin Stoll, Jaco Trenching began as a one-man operation with a truck and backhoe. Over the past 35+ years, we’ve grown into one of Gippsland’s most trusted names in trenching, directional drilling, and civil works. Our family-run business is built on reliability, safety, and getting the job done right—every time.
We specialise in essential underground services including water, gas, electrical, sewer, and communications infrastructure. Our clients range from local councils and contractors to utility providers and private developers.
With a team of certified operators, a modern fleet, and in-house project oversight, we manage everything from simple digs to complex infrastructure installs. And because we’re local, we understand the conditions, terrain, and expectations of working in regional Victoria.
