PBF Drainage were tasked with repairing a very difficult pipe running under a block and beam floor where rats had been causing major issues for the residents.
The pipe was DN100 vitrified clay and had been fractured and broken, either during installation or over time, with large sections of pipe missing and the pipe surround continually washing in causing the flows to backup.
Multiple other companies had tried to clear the collapse, which ran for approximately 8m in total, and then an additional 8m with severe breaks and fractures along the other sections.
Despite working through a very hot and sunny day, the team carefully removed the debris using a vacuum tanker, light jetting and mechanical equipment. The debris was removed and several patches were installed to secure the pipe during the cleaning process.
Any intruding sections of pipe and sharp sections of the pipe were cut back using a Hachler Climbolino E lateral cutter to prevent damage to the liner.
Once the pipe had been fully cleared, pre-liner was installed and two separate flexible felt liners were installed using Bluelight LED light cure equipment. The high strength and ease of installation of these liners prevented further damage and risk of total collapsed.
Once the liners had been installed, the Hachler Climbolino E that was hired from Bluelight Lining Ltd, due to its small size and very flexible cutting head, was used to reopen the connections to restore full flow of laterals from the sink and bathroom.
The entire system was then surveyed including all connections to make sure no other damage was present. The complete works took 2 days to fully complete, and the client was over the moon as the issues had been going on for the previous 12 months.
Well done to the team for getting the works done, efficiently, professionally and for taking care of the elderly client.
