Firth’s revolutionary flooring system RibRaft® EQ TC3, a system created by Firth to help Christchurch home owners deal with earthquake liquefaction in future events, was unveiled recently in Christchurch. Canterbury’s Earthquake Recovery Minister, Gerry Brownlee, launched Firth’s latest RibRaft® technology which allows for construction to sit ON the ground not IN it
Mr Brownlee spoke at the pouring of a new concrete foundation solution on a TC3 property in the Christchurch suburb of Hoon Hay with TV crews from New Zealand’s TV3, TVNZ, CTV and Mainland TV present. He thanked all those that had worked so hard to create viable options to speed up the delivery of solutions for Christchurch residents.
There are around 28,000 properties in TC3 areas – areas where damage from liquefaction is possible in future large earthquakes and further geotechnical investigation and specific engineering input may be necessary. Approximately 12,500 of these homes have major foundation and pile damage requiring further investigation of the ground around them. Engineers must look at TC3 land in more detail when deciding what foundations are required so the property will perform well and be safe in future earthquakes.
