The Sydney Metro Central Walk is an 80 m (265 feet) long and 19 m (63 feet) wide underground pedestrian concourse connecting passengers to trains, light rail, and the new Sydney Metro underground platforms. Running perpendicular to the Central Station tracks and above the new metro platforms 27 m (90 feet) below the station, the concourse will help meet a more than doubling of customer traffic expected over the next two decades.
PENETRON ADMIX, a crystalline waterproofing admixture, and PENETRON, a topically applied crystalline slurry, were specified to provide extensive waterproofing protection for the precast modules, shotcrete, and cast-in-place concrete elements of the underground concourse. PENECRETE MORTAR, a crystalline waterproofing repair grout, was also used to treat all internal tie bolt holes.
