Colebee Housing Estate


The residential estate of Colebee NSW was backing onto the noisy M7 Freeway in Sydney with an excessively high noise factor problem. There was a need for a sound barrier to allow the land to be buildable. The ground was not flat and the noise barrier needed to allow for integration of part retaining wall sections.


Evowall proved to be a turn-key solution. Installed at 2.4 metres high and 400 metres long, the Evowall was erected in just one week plus painting. Retaining wall sections were installed for part of the sound barrier and installation allowed for the ability to work around other trades making the final result timely and cost-effective.
