Carlton Mill Road, Christchurch >>
The 6 storey, Riverside Apartments on Carlton Mill Road suffered foundation settlement following the earthquake of February 2011.
It was proposed to relevel the building and strengthen foundations to provide better future seismic performance.
Jet grout columns, 2.5m in diameter, were installed from the bottom of the foundation to the dense, non-liquefiable sand layer. Grout injection techniques were also used in the relevelling process. As part of the design process, KGA reviewed existing geotechnical data for the site and assisted during the jet grout design and levelling to ensure it complied with the relevant New Zealand standards and codes.
