Grain Corp


Grain Corp is the largest Eastern Australian grain storage and transport network and came to Wallmark with a problem. Grain Corp required a noise barrier along with fire rated panels to protect their work site from unpredicatable bush fires.


Terrawall was accepted as the economical answer, installed at 4 metres high and 75 metres long. The Terrwall system effectively relfects the noise and uses polyisocyannurate foam to protect the site from the dangers of bush fires.
