Loosen the soil
Pressurised water breaks up and loosens soil within the targeted work area.
Controlled excavation around sensitive assets
Expose buried services.
Expose buried services.
Work with precision.
StrongVac uses pressurised water to loosen soil and powerful vacuum recovery to remove the resulting material—supporting controlled excavation around buried services and constrained work areas.

A controlled alternative
Dig where the site leaves little room for error.
Hydro excavation focuses work on the required area while helping limit unnecessary disturbance around nearby assets and surfaces. Water loosens the ground; the vacuum system recovers the material as part of the same operating process.
How the method works
Loosen. Recover. Expose.
One coordinated process combines controlled soil breakup and material recovery to create access around the required work area.
Recover the material
The loosened material is removed using the truck’s high-powered vacuum system.
Expose the asset
The process creates controlled access while helping limit avoidable disturbance around nearby services and surfaces.
Site applications
Where hydro excavation fits.
Use controlled excavation where buried services, restricted access, existing surfaces or sensitive surroundings make a targeted approach important.
Underground service exposure
Expose services for inspection, maintenance, repair or new installation near existing infrastructure.
Pole and pile holes
Create targeted holes in areas where access or surrounding conditions require a controlled approach.
Tight-access trenching
Excavate in confined areas where conventional digging equipment may be impractical.
Tree roots and vegetation
Support trenching around foliage and sensitive root zones with less unnecessary ground disturbance.
Footpaths and driveways
Reach beneath or around existing surfaces while limiting avoidable disruption.
Work around transformers
Support controlled trenching around transformers and nearby underground power services.
