Nexstone
A Colas brand, bringing together the production, recycling, and recovery of construction materials.
A Colas brand dedicated to the production and recovery of materials
From aggregate extraction to the production of high-performance concrete, Nexstone prioritizes local presence, quality, and resource reuse to reduce the environmental footprint of construction sites. Thanks to proven industrial expertise and a network of local facilities, Nexstone supports sustainable construction and the development of resilient territories.
Construction materials from an integrated model
As a key industrial player within Colas, Nexstone brings together expertise in producing essential construction materials:
- Aggregates sourced from managed quarries,
- Ready-mix concrete, designed to meet the technical requirements of construction sites,
- Recycled materials, produced from valorized construction and demolition waste.
This integrated approach ensures the traceability, quality, and environmental performance of every material. By reducing transport distances and controlling the entire production chain, Nexstone minimizes its carbon footprint while optimizing technical performance.
A dense and locally rooted industrial network
Present across France, Nexstone relies on a network of quarries, platforms, and local production units.
Each site combines industrial efficiency, local presence, and responsiveness, while optimizing resources available near construction sites.
This decentralized production model supports the activities of municipalities, businesses, and construction partners, promoting both proximity and sustainability.

Solutions supporting the circular economy and innovation
Recycle, transform, and reuse materials
At Nexstone, every resource matters. Materials from demolition or earthworks sites are collected, sorted, and then reused in the production of new aggregates and recycled concrete.
This circular approach allows for:
- Preserving natural resources,
- Reducing landfill disposal,
- And lowering CO₂ emissions.
In collaboration with group entities such as Valormat (recovery) and Premys (deconstruction), Nexstone participates in a virtuous cycle where every material is given a new life.
A key player in the sustainable transition of construction
Committed to Colas Group’s CSR strategy, Nexstone works toward a more efficient, local, and innovative materials industry. Its priorities include:
- Optimizing production processes to reduce energy consumption,
- Developing low-carbon concrete and high-performance recycled formulations,
- Promoting short supply chains and local material recovery,
- Supporting clients in implementing sustainable construction projects.
Nexstone combines industrial performance with environmental responsibility, advancing a more circular construction sector.
