SOPREMA WATERPROOFS THE UNDERGROUND WORKS
SOPREMA FLAGON PVC tunnelling system was installed in a few of the deepest stations on the city’s metro train line, which are expected to host large buildings above the stations: Martin Place, Victoria Cross, Pitt
Street, Crows Nest, and Waterloo Station sites.
Thanks to its flexibility and high mechanical resistance to geological movement and high hydrological pressure, SOPREMA’s FLAGON PVC system was chosen to waterproof these challenging underground structures.
- The waterproofing system can be repaired, even years after its installation, without any excavation or destructive investigation.
- The system allows for application onto wet or irregular substrates.
- Quality control of the waterproofing system is very reliable and easily achieved.
- High mechanical resistance to geological movement and high hydrological pressure are present.
- The system is cost efficient, on both materials and installation time levels.
- The system has a long service life.
THE INTRODUCTION OF AN INNOVATIVE PRODUCT TO THE AUSTRALIAN TUNNELLING INDUSTRY
Thanks to the John Holland CPB Ghella Joint Venture (JHCPBG) for selecting PVC membranes from SOPREMA. SOPREMA initiated a change to market trends and offered the Australian market a proven technology for waterproofing underground structures that is easier to install.
The JHCPBG Project Manager was impressed by SOPREMA’s overall service and was pleased to be associated with the introduction of an innovative product and a new company to the Australian tunnelling industry.
