WHAT IS HYDRO EXCAVATION?

Hydro excavation uses pressurized water to break up soil while a powerful vacuum simultaneously removes the slurry into a debris tank. This method exposes underground utilities and structures with precision and reduces the risk of damage compared to traditional mechanical digging.

This process is commonly used for utility locating, daylighting, potholing, test pits, and excavation in areas where underground utilities must be protected.
