Since 2002, the laboratory has been involved in the construction of living noise barriers along highways. The construction principle of these walls is based on the use of long willow stems, and exploits the extraordinary growth potential of certain species (in particular, Salix viminalis and S. miyabeana) as well as the capacity of these shrubs to root rapidly.
Through our research projects, we seek to verify the feasibility of this approach for urban areas in southern Quebec. We are therefore working with municipal partners to establish such structures, as well as provide scientific follow-up, in order to evaluate the pertinence and sustainability of these living walls in Quebec’s climatic conditions.
To date, living walls have been established in the Quebec municipalities of St. Bruno, Boisbriand and Laval. For more information, see this PDF document.
