The sequence of strong earthquakes in Canterbury in 2010 to 2011, most notably the devastating Mw 6.2 earthquake on 22 February 2011, the source of which was located within Christchurch, resulted in 185 fatalities and extensive damage to buildings and infrastructure. Liquefaction occurred on several…

This document has been produced in response to the Canterbury earthquake sequence that started on 4 September 2010 with the Darfield earthquake. The intention of this document is to provide guidance on what should be included in a technical specification when designing and constructing ground improvement (for liquefaction mitigation purposes)…
Abstract There are few practical methods currently available for liquefaction mitigation beneath existing structures, despite a growing demand for this due to a significant number of structures being targeted for seismic upgrading. One such method that is viable for liquefaction mitigation beneath existing structures is…
Resin injection has long been used internationally for the lifting or ‘level correction’ of buildings. For this purpose, expanding resin mixes are injected into the ground at relatively shallow depths, resulting in ground heave and building lift. It is logical to expect that this resin injection…
