Seismic Expansion or Movement Joints

As New Zealand has experienced earthquakes between 4.0-8.1 magnitude in the past 21 years. It's mandatory as stated by building code, that all new buildings are compliant with the rulings on seismic activity.

Scentre Group Design and Construct specified Unison's product for their new Westfield Centre in Newmarket, Auckland. Unison's expansion joint systems were compliant to the stringent code.
