About

Our Company History

TERRIX was founded with a clear purpose: to deliver professional, reliable sediment and erosion control solutions to civil, residential, and infrastructure projects across New South Wales and Queensland.


Since day one, we've built our reputation on quality workmanship, Blue Book compliance, and a hands-on approach that keeps projects moving. Over the years, we've successfully delivered projects across civil construction, renewable energy, infrastructure, and the public sector, building strong relationships with contractors, project managers, and government organisations along the way.


At TERRIX, our commitment to protecting sites and preserving the environment hasn't changed, and it never will.

Our Professional Background

TERRIX specialises in a full range of erosion and sediment control services, from silt fencing and coir logs to hydroseeding, drainage protection, and environmental compliance. Using specialised equipment, including vibrating plough installation, we deliver Blue Book-compliant outcomes efficiently and reliably.


Our experience spans civil construction, renewable energy, infrastructure, schools, subdivisions, and sewage treatment facilities across NSW and QLD, giving us the practical knowledge to handle projects of any scale or complexity.
