NDEA (Non Destructive Excavations Australia Pty Ltd) is Greater Sydney’s leading subterranean safety specialist, protecting underground infrastructure. Below the surface there is a vast city of subsurface utilities, buried infrastructure that supplies our gas, water, sewerage, electricity and communications. Whilst essential, these subsurface utilities pose a danger for any excavation or building work, any damage to the utilities can result in expensive damage claims, delays and possible injury to workers or the public. It is therefore critical to safely and quickly locate all the underground infrastructure before any site works. Most utility providers require that any contractor working with near their underground infrastructure, prove the existence and location of the utility, and some require the utility to be fully exposed before commencing any works. To achieve this Dial Before You Dig (DBYD) recommends the use of non destructive excation (potholing/trenching) as the best practice method to identify, locate and protect any subsurface utility. NDEA can perform all the required services in order to meet the DBYD requirements: Non Destructive Excavation (Potholing): Safe and effective method of exposing a subsurface utility using hydro excavation and vacuum techniques without damage Vacuum Excavation: Use a sucker truck to quickly and safely remove wet or dry materials Backfilling: Reinstatement of potholed areas, using sand, roadbase and cold mix Electromagnetic Locating – Use radio frequencies to locate subsurface utilities Roadsaw & Core Drilling – Quickly cut through asphalt and concrete CCTV Inspection. Check the condition of pipes, joints and find blockages easily
