Transnet – Leaking Drain Pipe

Transnet, Park Station, Gauteng Province, South Africa

Transnet had a 110mm cast iron drain pipe that had in some places rusted through completely causing water damage inside the building. The pipe ran within a concrete slab and replacing the pipe was not an option. There was also a 50mm pipe that tied into the main pipe from the urinals that was not inserted properly and was leaking.

Nu Flow South Africa used pull in place structural liners to reline the rusted pipe, even where the pipe had completely rusted away. Nu Flow relined the pipe without having to break through the buildings walls and floors. Nu Flow South Africa relined straight over the 50mm pipe and then reinstated the 50mm tie in.

The end result is a “nu pipe” with in the old pipe.
