Nexstone

Nexstone, formerly CMSE and part of Colas, is a major producer of construction materials serving the building, public works and civil engineering sectors in southeastern France. Its products include natural and recycled aggregates, ready-mixed concrete and precast concrete elements. The company also accepts, sorts, crushes and screens materials from construction and demolition, supporting their reuse throughout the materials life cycle.

Nexstone operates an extensive regional network comprising 37 active quarries, 27 materials platforms, 18 concrete plants, two precast factories, 20 recycling sites and 19 sites for receiving and transferring inert materials. The business employs 414 people. Its materials help supply projects such as roads, bridges, homes and public facilities.

The company promotes local supply chains and aims to reduce the environmental impact of its operations. Its commitments include protecting biodiversity, advancing the circular economy, rehabilitating sites and producing more environmentally responsible concrete. Nexstone also works to manage its impacts and engage with stakeholders, seeking to ensure that quarrying remains only one stage in the longer-term life of natural spaces.
