Deconstruction

Deconstruction is a key stage in the lifecycle of structures. It allows sites to be cleared, cleaned, and prepared for new uses while preserving natural resources.

With a responsible and certified approach, Premys, a subsidiary of Colas, supports public and private stakeholders in their deconstruction projects, from the initial assessment to the recovery of materials from the site.

Integrated expertise serving the sustainable transformation of regions

Thanks to its technical expertise and local presence, Premys works on all types of structures: buildings, industrial infrastructure, or sensitive sites. Our teams master all aspects of deconstruction: stripping out, asbestos removal, demolition, industrial dismantling, and material recovery, following a circular economy approach. Each project is designed to combine safety, environmental performance, and durability, thereby contributing to the sustainable transformation of sites and regions.
