Pionnering expertise in landscape restoration
Essential expertise for rehabilitation projects
We possess the full range of expertise and complementary knowledge required to manage your depollution and rehabilitation projects, whether they concern industrial, urban or natural sites, from start to finish.
Tailored solutions
We provide manufacturers, real estate developers and local authorities with solutions that are tailored to suit the characteristics of the site and ensure regulatory compliance, including making the site safe, using confinement where required, deconstructing buildings, removing asbestos (even within occupied buildings), conducting chemical, biological and pyrotechnical depollution and landscape restoration.
Controlling hazards
As leading experts in hazardous waste, we guarantee the highest standards in protecting human health and the environment. Our expertise in decontamination, along with our proficiency in various confinement techniques, enable us to treat asbestos, hydrocarbons, heavy metals (such as lead, mercury, zinc, etc.) and even pyrotechnic waste (including ammunition, airbag cylinders, and flairs).
Our employees receive specific training to guarantee the highest levels of individual and collective safety at work. They also monitor habitats, installing networks of piezometers on the outskirts of site, conduct compliance assessments and monitor air quality.
Furthermore, our laboratories characterize waste, and monitor environmental indicators (such as discharge into the air and water, analysis on soil and the water table), leading to pilot studies, which can be conducted in situ, to find an innovative response to suit each specific situation.
Toward a circular economy
Our solutions to recover waste, the energy contained in waste, as well as reuse excavated land, enable our clients to reduce their overall environmental footprint.
Tailoring projects to you
Studies and decision-making tools
We assess the cost of work, develop innovative solutions, analyze samples in the laboratory, and conduct work upstream, including the preliminary draft plan, preliminary measurements, and implementation studies.
