Safe and precise vacuum excavation technology

Our vacuum excavation services use high-pressure water and industrial suction to dig without disturbing underground utilities. It’s the safest method for working around electrical, water, gas, and comms infrastructure, especially in tight or high-risk sites.


Traditional digging methods can damage vital underground assets. Hydro vac digging reduces this risk significantly, making it ideal for complex or congested environments.

Why choose vacuum excavation

  • Non-destructive utility location  – expose underground cables and pipes with zero damage
  • Reduced risk of service strikes – protect assets and avoid costly repairs
  • Precise excavation in tight spaces – ideal for urban or constrained sites
  • Minimal site disruption – clean, controlled and less mess than mechanical digging
  • Compliant with safety regulations – meets all BYDA and site safety standards
  • Fast and efficient process – complete more work with fewer setbacks
