Newcomen Street Retaining Wall Remediation

Sector Public Domain
Year Completed 2011
Location Newcastle, NSW
Client Department of Commerce
Value $6m

The existing convict built (1840’s) retaining wall along the boundary of Newcomen Street, Newcastle, adjacent to John Hunter Hospital was unstable and threatened the heritage listed houses below. 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. 6 mature age palms were carefully replanted in order to preserve the traditional beachside ambience traditionally associated with this historical area.
