Utilities worldwide rely on Radiodetection Cable Avoidance Tools (C.A.T®) to prevent accidental damage to underground services when excavating. Trenchless products enable pipe-laying companies to direct the drill and so speed installation of utilities. Radiodetection's cable test products quickly locate problems such as breaks or deteriorating insulation. Down-hole inspection products from Radiodetection use the latest digital CCTV in difficult environments to enable water companies to perform regular inspection and maintenance, troubleshooting and repairing sewer and other pipes. A range of dehydrator products is available as a fixed installation in telephone exchanges maintaining cable health.
