CCTV Inspections

USi specializes in CCTV inspection of pipeline.  Our equipment will traverse 6” pipe to tunnels providing clear visual data of every defect we find.  Every one of our CCTV operators is PACP qualified and has undergone extensive training before making calls in accordance with NASSCO guidelines.  Our Quality Assurance / Quality Control staff provides a valuable check to make sure we get it right before submitting any data to our clients.
