Creation of an Ecoproduct - Leroy Merlin


An innovative deconstruction-reconstruction operation of a Leroy Merlin building in the Lille metropolitan area generated an eco-product when crushing the concrete slab of the existing store: concrete fines.

In partnership with EtNISI, a material creator based in Roubaix in the North of France, we reused concrete fines as well as foundry sand in combination with a binder to create tiles from used materials.
