Improving the performance of concrete structures

A9 motorway

Eleven roadway water treatment structures for the A9 motorway upstream of the infiltration basin were not providing complete satisfaction, in particular concerning the protection of the water in the vicinity. Saint Dizier Environnement was therefore mandated in 2010 by the client to audit the structures in place in order to compile a technical proposal for improving the purification performance.
