The Canterbury earthquakes severely tested interior linings and bracing systems, and GIB® systems performed extremely well. In doing so they protected homes and people from more serious harm.
With the recent seismic events in the Wellington and Upper South Island regions in mind below are links to specific information that will assist in the assessment and rebuild process. More information will be added as we continue to investigate and determine the best ways to deliver GIB®plasterboard systems that are the most efficient and effective for specific applications.
Testing at Canterbury University shows how flush finished non-structural plasterboard partitions in commercial buildings can suffer significant earthquake damage, even at low levels of inter-storey drift. To see these tests in action please click on either of these links below:
