CM2 structure in Rodez

Hydraulic works of the stream of Las Combes in Rodez

Currently, our concrete teams are moving in the Aveyron for the construction of a hydraulic structure on the stream of Las Combes in Rodez.


This new work is part of the RN88 project to create a link between Rodez and the A75 motorway and to develop the section Rodez-Causse Comtal. This development project includes no less than 12 new structures, 2 of which have been entrusted to Matière®.

One of them, the OA5 of Las Combes is also being finished.


This project will have mobilized the skills of our earthworks and civil engineering teams.
