WestConnex Highway Tunnels

Sydney, Australia

Description

WestConnex is designed to improve connections between Sydney’s eastern and western districts, ease congestion, and link the city’s network of highways. The $16.8 billion project is the largest road infrastructure project ever undertaken in Australia. This stage of the highway network expansion encompasses 33 km (21 miles) of mostly underground highway.


Products Used

During the planning phase of the WestConnex tunnels, the project engineers needed an optimal concrete admixture that would ensure impermeable and durable concrete tunnel walls for the most recent phase of construction. Penetron Australia provided test results that showed how PENETRON ADMIX-treated concrete provided enhanced corrosion resistance and substantially improved the durability of concrete, even under the high hydrostatic conditions of the subterranean tunnels of the WestConnex highway network.
