Atrium on 5th, Sandton City

Site:
Atrium on 5th, Sandton City

The Atrium on 5th, previously known as the Twin Towers offices, was refreshed in 2014 with a facade and the introduction of a glass atrium which centrally links the two structures from top to bottom, creating a statement feature for this 32 year old iconic property in Sandton CBD.

Situation:
When such a state of the art building in the heart of South Africa’s busiest city experiences piping problems, only state of the art technology can be used.

Contractors were replacing a number of old galvanized pipes in the building, which were exposed and easily replaceable. However there was a 110mm and a 160mm galvanized pipe running under concrete and walls. Management were not keen to have these pipes replaced as this would involve chopping open sections of walls and floor slabs. The contractor awarded the pipe replacement project contacted Nu Flow for a non-invasive solution.

Solution:
Nu Flow’s technicians cleaned and descaled the galvanized pipes using Nu Flow’s specialized Micro Cutter cleaning machine. Nu Flow then relined the pipe with Nu Flow’s structural lining technology.

Epoxy saturated liners were pulled into the pipes. Within the liners is a rubber bladder, which is inflated when the liners are in position.
The bladder is left inflated until the epoxy has cured. Once the epoxy has cured, the bladder is removed leaving behind a ‘nu pipe’ within the host pipe.
