Oxidation ponds at the Christchurch wastewater treatment plant 

To deal with damage to the Christchurch sewer system as a result of the February 2011 earthquake, the city awarded rehabilitation and soil improvement works to March Construction, a New Zealand subsidiary of Menard Bachy. The goal was to reconstruct the levee banks of the oxidation ponds and treat the soils in place to prevent liquefaction under seismic loads. This was accomplished by the Vibrocompaction technique. The project also included the construction of 51,000 linear metres of access roads and 3 hydraulic structures to transfer water between the ponds and the estuary. 

The Menard group develops foundation solutions based on ground improvement and reinforcement technologies. Its treatments eliminate the need for the deep foundations traditionally used to support surface structures.
