Highways A71/A72, Germany 

The new alignment for the construction of A71 and A72 motorways in Germany had to go through areas where active collapse sinkholes could be encountered. A special application of Dynamic Compaction was developed for these projects by using very high-energy pounding with the patented MARS free fall system. Up to 6 m deep craters were created by this treatment allowing to collapse of the potential sinkhole. 

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.
