The Australian teams implemented 58 jet grouting columns 

The columns were installed to stabilise the soil in the heart of Adelaide and to support the creation of priority lanes and a tunnel for the O-Bahn guided busway. 

Created in the mid-1980s to relieve traffic congestion in the city, the O-Bahn continues to modernise and adapt to new patterns of mobility and the growth of new neighbourhoods. 

In addition to the jet grouting columns (with diameters ranging from 1.2 to 1.6 metres), 36 temporary ground anchors were installed. A cyclone with winds gusting at 140km/h and heavy precipitation disrupted the work. 

Between September and October 2016, Menard made its expertise and professionalism available to its client McConnell Dowell, coping with the complex weather and ground conditions, carrying out the project near road traffic and removing muddy spoil via vacuum trucks so as to protect the environment and avoid unpleasant site impact on local residents and motorists.
