We’ve had a relationship with Ranelagh for over 15 years now. At first, they asked us to reline their nine-inch boundary trap. Since that time, we have relined most of their subsoil exterior drainage. Over time, the building realised that they were actually starting to develop issues with the cast iron stack drainage. Cast iron is now defunct material, and it actually rust from the inside out.
Some of the symptoms that the residents were experiencing in relation to the dilapidated cast iron network were smells, leaks, blockages, and in the most extreme case, flooding. It would have been best if we could actually move the residents out of the building. Because that was logistically impossible, we had to break down the project into individual length reline shots. We brought on our friends from Time to Reline, which enabled us to have two inversion teams and two junction robot teams doing two shots per day and also cutting out all the junctions as necessary. We were able to reline over a kilometre of drainage, do 800 cuts, and remove one and a half tonnes of metallic silt within a six-week time period.
