Hydrovaccing
Hydrovaccing uses high-pressure water and powerful vacuum systems to safely break up soil and remove it without damaging underground utilities.

Hydro Excavation: Safe, Precise, Non-Destructive Digging
Hydro excavation is a modern, non-invasive method that uses pressurized water and a vacuum system to break up and remove soil with precision. It’s ideal for exposing underground utilities, digging in tight or urban spaces, or working near sensitive infrastructure.
At 3 Gen Excavation, we use advanced hydro excavation equipment to safely access and dig around utilities, pipelines, and foundations with minimal disruption. This method greatly reduces the risk of damage compared to traditional mechanical excavation.

Michael Z. President
"I have had the pleasure of working with 3 Gen Excavation on various projects. These projects consisted of excavation for underground plumbing on a classroom building, lab facility, and some maintenance facilities. Each of the buildings required accurate excavation due to constricted schedules and 3 Gen exceeded our expectations each time. Throughout the project that required multiple mobilizations, the 3 Gen team delivered consistent professional service. Communication from the 3 Gen team is timely, direct, and professional. This is a contractor that stands behind their word and their work and delivers on their slogan "On time. On Budget. On Grade." We will continue to use 3 Get Excavation on future projects because of their unparalleled professionalism and quality of service. It is a peace of mind that I can continually count on consistent and quality service from 3 Gen Excavation as a subcontractor. Our underground plumbing needs have been successful because of the expertise 3 Gen Excavation has brought to our projects."
