Who We Are


DERT is a joint venture between OPEC Systems and Liberty Industrial that has been strategically established to combine the capabilities of two of Australia’s most progressive remediation companies to provide leading edge, comprehensive, large scale site remediation and demolition services for complex contaminated sites.

In conjunction with our proven remediation technologies and deconstruction expertise, DERT is able to deploy teams of highly trained technicians skilled in managing some of the complex engineering, safety and environmental risks potentially encountered at the DSM site such as UXO, explosive residues, asbestos, heritage and environmental remnants and engineering works adjacent to waterways and residential precincts.

DERT draws upon the internal resources of OPEC Systems and Liberty Industrial to execute and support projects throughout Australia. These significant resources include over 150 staff and a broad portfolio of plant and equipment regularly used on civil engineering, remediation and demolition projects. DERT is a matrix organisation and resource sharing between state offices is regularly practised. This capacity allows DERT to combine the right staff and specialist equipment for any project throughout Australia.
