  • Polishing (fat removal)
  • High-pressure root cutting
  • Urethane pressure grouting to seal leaks in manholes, joints, lines and connections


  • Specialised Panoramo system captures still images as it moves through the pipeline, which overlaps to produce high-resolution 3D colour digital modelling and dimensioning
  • Panoramo downhole camera for detailed manhole and soak hole imaging and measurement
  • Large tractor units and smaller units operated from the same multi-capable vans – for pipelines 50mm to 2m in diameter

  • Real-time viewing and/or video reporting for offsite analysis


  • True 3D modelling with Panoramo for high-quality and detailed colour imaging
  • Six times greater than the traditional resolution
  • Image does not blur when mouse scrolling along the pipeline, even at the highest speeds
  • Zoom capability and powerful LED illumination (with additional bolt-on lighting) to enable clear focus and easy views of high or overhead inlets

  • CCTV consent compliance work for new subdivisions in Christchurch and Auckland – in Christchurch, this has involved working under tight time pressures to get the post-earthquake rebuild underway
  • CCTV services to facilitate the ongoing maintenance of Auckland’s extensive sewer, water supply and stormwater networks for Watercare and other clients
  • Cyclic CCTV sanitary sewer inspections and cleaning for Gisborne District Council
  • In the industrial sector, CCTV inspection and cleaning of Fonterra’s milk powder ducting
I’ve been using Intergroup for five years now. Their service is very good – we always get a quick response and they always do what we want. We get on well with the crews and they are willing to go the extra mile for us. Problems with drainage can occur at unusual times but they respond promptly no matter the hour and help us complete inspections with CCTV. In my view, they’re a very good company.
