Non Destructive Digging (NDD)

Non-destructive digging (NDD) is a precision excavation method that uses high-pressure water and vacuum systems to expose and clear ground without risking damage to existing underground services. This approach gives you clean, controlled excavation that protects utilities such as power, communications, water and gas infrastructure while reducing surface disruption.

Teoma’s NDD services fit seamlessly with trenching, conduit installation and site preparation, giving you a safer and more accurate option for excavation in tight or congested areas.

  • Hydro excavation and vacuum recovery

  • Excavation in high-traffic or sensitive areas
  • Pre-installation site preparation
  • Asset protection during trenching or boring works

  • Horizontal directional drilling (HDD)

Safe, Accurate Hydro Excavation for Civil and Electrical Works

NDD is the go-to choice for projects where traditional mechanical digging could cause costly strikes or service outages. By loosening soil with controlled water pressure and removing it with powerful vacuum systems, we preserve underground infrastructure while giving you safe, fast access without disruption.

Our team integrates non-destructive digging into broader civil and electrical scopes, delivering compliant, low-risk excavation that suits high-traffic or restricted sites. We bring the experience, accreditation and coordination that keeps complex projects running smoothly and delivered to the highest standard.
