Our highly trained crews are certified in the transportation of dangerous goods, confined space entry, hold current First Aid & WCB safety training standards, and are equipped with the tools required to enable a safe work site.

Residential Services

“Non-destructive hydro excavation”, performed with a hydrovac unit, is the process of using high-pressure water to break up various earthly materials. This material and water mixture is continuously vacuumed up into a debris tank for later disposal.  

Hydro excavating is a much more efficient method than hand-digging, yet far less evasive as other hydraulic means, making it the perfect option for your residential excavation needs!

While hydro excavation remains our main area of focus, check out our several other services listed below: 

  • Liquid waste management & disposal
  • Utility locating with BC One Call
  • Tank pumping & cleaning (septic, holding, etc.) 
  • Storm & sanitary sewer system maintenance 
  • Fluid transfer & water intake  
  • Material storage & disposal
  • Utility pole hole & anchor installation
  • Custom services, we’re always eager for a challenge!
