Liquefaction

The devastating effects of liquefaction induced damage include slope failures, bridge and building foundation failures, and flotation of buried structures. Liquefaction occurs when water pressure builds up in soils during earthquake shaking, turning the soils into a wet ‘jelly-like’ consistency, and leading to a severe reduction in their strength.

Tonkin & Taylor has a team of experienced geotechnical engineers and engineering geologists specialising in the investigations and analysis required to firstly determine whether a susceptibility to liquefaction exists, and secondly to develop practical and cost effective remediation solutions, such as stone columns and dynamic compaction, for those sites that are susceptible.

Expertise

The expertise T&T has to offer, as New Zealand’s largest geotechnical consultancy, has been gained while working on:

• Site development projects (residential, commercial and industrial)
  
• Landslide assessments and remedial design
  
• Oil and gas storage tank farms
  
• Major infrastructure developments including hydro electric power schemes, road and rail projects, port and harbour developments, water supply and solid waste (landfill) developments
  
• Airport and air industry projects.

Working closely with our clients and contractors provides the essential inputs to develop practical engineering solutions that meet client needs and economic constraints.

Our team can provide invaluable advice ranging from proven empirical solutions to the latest dynamic numerical methods to best suit the problem you are faced with. We provide services ranging from specialist analysis to detailed design, supervision and monitoring of your entire solution. This service can be tailored to meet client specific needs.
