What is Hydrovac Excavation?
Hydrovac excavation, also known as hydro excavation or vacuum excavation, is a non-destructive digging method that employs high-pressure water and a powerful vacuum system to safely expose and extract soil, debris, and underground utilities. This cutting-edge technique utilizes a hydrovac truck, equipped with a water tank, pressure pump, suction system, and debris storage, to create a controlled excavation process.
How Does Hydrovac Excavation Work?
The hydrovac excavation process begins with the hydrovac truck positioning itself near the excavation site. A skilled operator controls a wand attached to the truck, directing a high-pressure water stream to break up the soil and create a slurry. Simultaneously, the powerful vacuum system extracts the slurry, depositing it into a debris tank for later disposal. The extracted soil and debris are carefully separated, allowing for further analysis if required. By gradually excavating the soil layer by layer, hydrovac excavation provides precise access to the subsurface, reducing the risk of damage to underlying utilities.
