Hydrovac excavation is a non-destructive excavation method that uses high-pressure water to break up and liquefy soil while simultaneously removing it with an industrial vacuum into a truck-mounted debris tank. No mechanical equipment contacts the ground during the process.
Trenchless vs open cut trenching is not a question of which method is better. It is a question of which method fits the site. On developed urban roads, crossings, and congested utility corridors, trenchless methods typically deliver lower total project cost because they eliminate the restoration, traffic control, and excess soil costs that inflate open-cut budgets. On greenfield sites with no pavement to protect, open-cut remains faster, simpler, and cheaper. The tender documents should force that analysis, not default to either method by habit.
Horizontal directional drilling is a steerable trenchless method that installs new underground utilities by drilling a guided bore path beneath the surface and pulling product pipe through the completed hole. The process works in three stages: a steered pilot bore establishes the path, a remaining pass enlarges it to accommodate the product pipe, and a pullback operation pulls the pipe into position. The surface above the bore path remains intact throughout.

An underground utility contractor installs, repairs and supports underground infrastructure such as water, sewer, telecom, hydro, fuel and geothermal systems using specialized construction methods and equipment.
CC Underground provides horizontal directional drilling (HDD), hydrovac excavation, utility ploughing, HDPE pipe fusion, geothermal loop installation and related underground construction services across Ontario.
Hydrovac excavation uses pressurized water and vacuum removal to safely expose underground utilities, daylight services, slot trench and excavate around existing infrastructure with less surface disruption.
HDD provides trenchless installation of water, sewer, telecom, hydro and other utility lines beneath roads, rail corridors, waterways and developed areas while minimizing surface disruption.
The company is registered with ComplyWorks , has CROR-qualified crews for live rail corridors, and is currently pursuing COR certification through IHSA.
