How does a Hydrovac Excavation work?

How does Hydrovac Excavation work?Hydrovac trucks rely on two main components.

First, high pressure jets of water are used to loosen the material that is being excavated.

Second, a very strong vacuum hose sucks the loosened material and excess water into a large holding tank.

Hydrovac trucks can be used to excavate almost any type of material that typically needs to be excavated on a construction site, including hard packed clay, sand, ice and gravel.
