- Section 175 guidance
This module provides a specification for designing and constructing ground improvement. It is specifically directed at ground improvement for liquefaction mitigation in single residential properties in Canterbury. However, it will also be useful for other areas of New Zealand prone to liquefaction.
The module covers four of the main ground improvement techniques. This is part of the Earthquake Geotechnical Engineering Practice series.
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) for the four
ground improvement techniques covered by this document. It is intended that the guidance is used
for small scale ground improvement Works as typically required for single residential sites (typically approximately 500m2 plan area).
