This project entailed the remediation of a 19th century convict-built retaining wall along the boundary of Newcomen Street, Newcastle. The remediation included complex wall reinforcement achieved by the design and installation of jet grout columns in a mass gravity arrangement behind the existing wall; ground anchors, wall repairs, road restoration and construction of a new sandstone retaining wall. To preserve the traditional beachside ambience associated with this historical area, six mature age palms were carefully replanted along the street.
