Developed in consultation with the town of Loison-sous-Lens, this new nature and leisure area is part of an initiative to enhance the living environment. Located near the banks of the Souchez river, the park is a natural and recreational area combining ecological facilities and leisure zones accessible to all.

Explore our photo gallery dedicated to the manufacture and installation of the fertile substrate for the future Parc du Sempin in Chelles. These images illustrate every stage of this innovative process, from the preparation of green waste compost and inert soil from the construction industry to their mixing and application on site. Find out how our teams transform these recycled materials into fertile soil, ready to be planted in the park.
