Nu Flow re-lines leaking stacks at The National Union of Mineworkers building

National Union of Mineworkers, Johannesburg, Gauteng

The National Union of Mineworkers building, a national heritage site, was experiencing water damage due to leaks in the old cast iron storm water pipes running from the roof down all 7 floors.

The pipes run with in the old buildings walls from the roof to the ground floor. Replacing these pipes using traditional methods was not an option due to the fact that the building is a national heritage site and traditional pipe re-placement would cause permanent scarring to the building detracting from its original state.

The building owners turned to Nu Flow for a solution.

African Pipe Re-lining, a Nu Flow licensee first did a CCTV pipe inspection to assess the pipes condition. African Pipe Re-lining then cleaned the old corroded cast iron pipes using Nu Flow’s unique cleaning tools.

Once the line was cleaned African Pipe Re-lining relined the stacks using Nu Flow’s pull-in-place structural liners working from existing access points and therefore without having to break through the buildings walls.

No damage to structures, no mess, no disturbance!
The end result is a new pipe with in the old pipe.
