A new ecological noise barrier in Gatineau
At a time when noise pollution is a growing issue for the health of Quebec residents, the city of Gatineau installed a Ramo noise barrier as part of its project to widen chemin Pink from two to four lanes. An aesthetic, natural solution that delights local residents.
Chemin Pink, August 15, 2022. The widening of chemin Pink aims to improve traffic flow and enhance the safety of pedestrians and cyclists, while ensuring peace and quiet for nearby residents. The noise barrier is 223 metres long and made of willows, rock wool and larch.
"We hear much less noise than before since the noise barriers were installed, and the noise from trucks passing on chemin Pink is less pronounced."
This acoustic solution is carbon-negative, maintenance-free and blends seamlessly into the urban landscape. The technology is tested and proven to meet standards and requirements for quality, durability and acoustic performance. The willows used are grown by Ramo and capture a significant amount of CO₂. The addition of climbing plants greens the structure, giving it a unique design and aesthetic. A noise reduction of 5 to 12 dBA can be achieved for an area protected by an acoustic wall.
The city of Gatineau also called on several partners to carry out this project: WSP for engineering and design, Pavage Coco for the site works and les Entreprises JC Beaudet for installation.
