Leighton Contractors was engaged to develop the Southern Cross Station, previously, the Spencer Street Station. Stone sealers and cleaners from Rockstar Sealing Systems were used by the contractor during the development of the historic site.

Rockstar Sealing products were chosen as the preferred sealing system for the award-winning station.

Rockstar Natural Finish Stone Sealer, Rockstar Dense Stone Sealer, Rockstar Miracle Cleaner and Rockstar Neutral Cleaner were used on 13,000 square metres of Bam Bluestone to provide superior protection in this extremely high traffic environment.
