Following the New Zealand earthquakes of 2010 and 2011, the footings of Christchurch's Art Gallery sank unevenly across the entire footprint. It tilted 182mm to one side.
Mainmark NZ initially strengthened the foundations by jet grouting 124 soil-crete columns. This was then followed by the re-levelling of the structure using JOG computer-controlled grouting at 350 injection points across the structure. Using 1,500,000 litres of grout the Art Gallery was raised to within millimetres of the correct levels.
During the whole process the building was able to be occupied by the Art Gallery staff.
