Expansion Joint Systems for New Zealand’s Seismic Building and Design Changes

By inherently factoring all aspects of the new seismic design and assessment criteria reflected in the Building (Earthquake-prone Buildings) Amendment Act 2016, which introduced major changes to the way earthquake-prone buildings are identified and managed under the Building Act 2004 throughout New Zealand, the joint systems Facade Interaction Joint utilises unique manufacturing and design to encapsulate and protect entire building facade envelopes from the effects of fire, wind and acoustics whilst compensating for thermal (low range) and seismic (high range) movement.

joint systems, in conjunction with some of the world’s leading architectural designers and product specialists, developed the Facade Interaction System specifically for the new changes to the Building Act (Amendment) in 2014 by adding a new level of acoustic performance to Preformed Polyurethane Expansion Joints. The Amendment in 2016 has been added after several years of strong seismic activity with the Public’s safety in mind.

The recent changes addresses New Zealand’s “Degrees of Seismicity” as they reflect three seismic risk areas or zones, and sets time frames for identifying and taking action to strengthen or to remove earthquake-prone buildings entirely.

Fix Faulty Expansion Joints | New Zealand | Joint Systems Expansion Joints

As a custom solution provider, joint system the expansion joint division of retained earth, through years of product development and project experience, can deliver retrofit expansion joint products for the repair and replacement of defective joint seals and sometimes as a result, dangerous situations for your patrons and employees.

Through cyclic fatigue, it is inevitable that the seals positioned in walls and floors will deteriorate, albeit, some quicker than others.

Expansion Joints and Seismic Compensators for Earthquake Affected Structures | New Zealand

New Zealand is a highly seismic country with a long history of living with the constant presence of earthquake events. With the most recent event in Christchurch damaging a large amount of existing properties, some to a great extent, the National Building Codes have been adjusted to cater for new and improved regulations in order to further protect the public through the increased design and overall focus on seismicity.

retained earth are pleased to offer a vast array of product solutions relating to the protection from these earthquake events. With our product range including joint systems™ expansion joints and movement compensation systems such as reinforced and un-reinforced bearings, retained earth can design a suitable solution for both new build and retrofit/ remedial projects.

Global Stability : The Retained Earth Philosophy | Systems Development

When speaking in a Geotechnical Engineering sense, “global stability” relates to the overall stability of a structure. This extends outside the typical design considerations such as structural adequacy or “internal stability” and relates to preexisting site conditions such as seismicity or acceleration and general soil types and how they affect the internal design.

Retained Earth, as a business philosophy, have adapted this engineering consideration into our general business methodology and approach. We endeavour to encompass all components of seismic effects on buildings and general soil structures.

This is reflected in our approach in creating various cutting-edge systems in the retaining of soil and the buildings that are supported above and also the protection of the structure itself as it experiences the cycles of expansion encountered through thermal and seismic movement.
