Underground & Civil Works
Non-Destructive Excavation
Safely expose underground infrastructure before construction begins.
Non-destructive excavation (NDE) uses pressurised water or air together with vacuum recovery to break up and remove soil without the mechanical force of conventional digging.
Because the excavation method itself is far less likely to damage what it uncovers, NDE is well suited to exposing live telecommunications, electrical, water and gas assets in congested or sensitive locations.

Benefits
Why Projects Use This Approach
Reduced asset damage risk
Soil is removed without striking the service being exposed.
Greater excavation accuracy
Small, controlled excavations confirm exact position and depth.
Lower surface disruption
Smaller footprints mean less reinstatement and less impact on access.
Suited to congested sites
Practical where multiple services share a narrow corridor.
