In case of a big flood in the region, a trench was planned to allow the transfer of water to temporary storage (quarry).
The trench is partly equipped with a reinforced concrete framework, while a linear of about 60 meters remains in the open air and must be reinforced to avoid landslides
The exposed rock face has fractured planes that can generate local instability. TECCO system, consisting of a G65/3 mesh associated with a P33 spike plate, was selected.
The resistance of the TECCO G65/3 mesh allowed us to propose a flexible-facing solution adapted to the site.
