Project Description

Project Details

Airport Link is the longest road tunnel in Australia. It includes road header and TBM tunnels with multiple cut and cover on and off ramps.


This complex project required diverse application methods for the waterproofing of all sections without excavation.


BCS managed the waterproofing of the TBM tunnels and most on and off ramps in 2010 – 2012. The company also developed and implemented a new system for the back grouting of Smoke duct roof supports.


BCS specialists used their engineering expertise and experience to develop quality solutions and meet the unique challenges of this construction project.
