• NIA Repair projects

     

    Our award-winning CISBOT, the cast iron joint sealing robot that enables us to repair older gas mains from inside the pipe, is only one of our NIA repair projects. CISBOT's pioneering technology minimises disruption to the general public as there’s no need for multiple excavations in the road and repairs can be carried out without shutting off the gas supply. The system is being used on larger mains in inner city locations and it also dramatically reduces the distribution company’s carbon footprint.

    CISBOT has won numerous accolades, most recently Innovator of the Year at the London Construction Awards.

    Our gas polymerisation project aims to demonstrate ‘proof of concept’ of the innovative  gas polymerisation technology, which uses gas sealants transported with the gas to remotely repair leaks by exploiting chemistry that reacts with unique environmental factors found at leak points.
