Solo is fixing Auckland’s dirty beaches under your feet – but you would never know. Solo is the country’s largest provider of onsite welding for plastic pipes and in this video, Solo’s highly trained technicians can be seen at work inside a 2.5m diameter branch of the Central Interceptor tunnel, sealing the joins. This is no quick job for Solo, the site teams start on the giant 4.5m diameter cavern of the main line soon!
