Southern Response - foundation repair trials
From the Southern Response website (here):
Southern Response is partnering with Housing New Zealand to trial different methods of re-levelling earthquake damaged houses on TC2 and TC3 land. The trials are specifically for houses with concrete ring and concrete floor foundations. Housing New Zealand has produced two video clips - the first clip is an explanation of the project by structural and geotechnical engineers and the second clip is a demonstration of the jack and pack method of re-levelling. The website also includes a recorded presentation on foundation repairs from the CERA rebuild and recovery expo held in April 2013.
