An innovative solution for the CSIR

The Council for Scientific and Industrial Research, commonly known as the CSIR, is a world-class African research and development organisation established through an Act of Parliament in 1945.

When the CSIR building was experiencing water damage from leaking bull bores, the innovative facility did not hesitate to call in Nu Flow.

The problematic down pipes are a combination of 50mm and 75mm Galvanized and PVC. The pipes run within the buildings walls and columns passing through floor slabs thereby making a traditional pipe replacement nearly impossible.

Nu Flow camera inspected the pipes to determine how much pipe was in need of lining and how much cleaning was needed. The galvanized pipes were then cleaned and descaled using a Nu Flow micro cutter to remove all rust and scale build up. Once the pipes were cleaned, descaled and returned to their full diameter the pipes were relined using structural liners.

How it works:
An epoxy saturated liner is pulled into the pipe.
With in the liner is an inflatable bladder. When the liner is in the correct position the bladder is inflated and left inflated until the epoxy has cured. Once the epoxy has hardened the bladder is removed leaving behind a “nu pipe” within the host pipe.
