Hydro Excavating is

The process of Hydro Excavation, the only non-destructive method of digging, utilizes pressurized water and a vacuum system to quickly and safely expose underground infrastructure.

During the hydrovac process, pressurized water is injected into the ground through a handheld wand. As the soil cover is liquefied, the resulting slurry is simultaneously extracted by a powerful vacuum and stored in a 14 yard HydroVac_Excavating_Times_Squaredebris tank onboard the hydrovac.

Hydrovacs can dig effectively in all soil types, including clay, and with the aid of onboard heaters, hydrovacs provide a safe means of digging in frozen ground. Our powerful hydrovac systems can excavate up to 60' deep and at distances of 600' from the truck, enabling work to be done in areas of limited access. 

We recently completed a job for the City of Kingston, NY vacuuming out debris from a tunnel collapse 90 feet deep and 220 feet laterally.

How Hydrovac Can Help You

Beneath the soil lies a complex maze of facilities carry petroleum products, electricity, water, wastewater, natural gas, and telecommunications. Every single day incidents occur across the country that leave utilities damaged, property destroyed, and sometimes, workers injured or worse. The added cost of using a hydrovac on a project can be negated by the increased productivity achieved on the job. By clearing a path through utility conflicts, a hydrovac can help contractors put more pipe in the ground per day, install more poles per day, or complete more service repairs in a day.

Hydrovacs add value to projects by helping contractors get more out of their existing resources. The beauty of the hydrovac solution is that all of this can be done without the risk of causing damage to existing infrastructure. Improved productivity and safe work methods translate into profit for those working in today's underground environment.
