BC railway sound barrier turns into a real tree-hugger

November 3, 2015

In Port Moody, BC, the Klahanie Strata Council was concerned that the addition of the Evergreen Line LRT service to an existing CP Rail corridor would create even more unwanted noise for the property owners it represents. The AIL Sound Walls team consulted with the Council to come up with an effective sound mitigation solution that would be acceptable to both the Council and the BC Ministry of Transportation and Infrastructure. 

Little did they know, that their new sound barrier would turn out to be a real tree hugger – standing tall through one of the worst storms in BC’s recent history.

To the delight of some of the bordering property owners, the nimble nature and design flexibility of our lightweight wall with smaller footings, allowed it to deftly deviate around some of their beloved mature trees and hug very close to others in the straight sections of this 169 m installation.

With our wall partially installed, the worst storm in more than a decade hit southwestern BC. This caused severe damage to many homes and trees, knocking out power to half a million people for days. On returning to the site after the storm, there was no damage to our wall and it performed as it was designed to – perhaps even protecting its new-found leafy friends.
