Flinders Street Railway Station 

The Challenge
Increase the structural strength of the Station's concourse to enable it to cope with the increased loads associated with current activities while preserving the historic value of this Australian icon.

The Solution
The concourse level upgrade works incorporated the use of state-of-the-art MBrace Fibre Reinforcement System.  Based on Carbon, Aramid and Glass fibre technologies, MBrace provides the ideal combination of high strength, lightweight materials and corrosion resistance.  The Flinders Street Station application involved the application of MBrace CF120 unidirectional carbon fibre sheets to the underside of the concourse structure.

Once the build-up of dirt and grime had been removed from the underside of the concourse slab, exposed cracks were injected with Concresive 1375, a low viscosity, high strength epoxy injection resin.  The surface was then levelled with BASF's Concresive 1444 - a thixotropic epoxy mortar paste binder and adhesive - prior to the application of the MBrace CF120 sheets, which are held in place using the specially formulated MBrace Saturant.  Over 2000m² of MBrace sheets were used in the Flinders Street Station project.
