The $58 million Burrill Lake Bridge project, located on the Princes Highway, just south of Ulladulla, involved the construction of a new bridge over salt water. The new bridge, with access for pedestrians and cyclists, features reduced future maintenance needs and will withstand 100 years of flood event conditions.
To ensure durability of concrete structures exposed to a marine environment, NSW Roads and Maritime Services used the Penetron System to waterproof the precast prestressed beams. This helped the project meet RMS B80 compliance guidelines and address the high chloride content in the air. The use of Penetron products also enhances the overall durability of the bridge, increases resistance to extreme weather events, and reduces future maintenance.
