What Demex does

DEMEX is an Australian specialist demolition, remediation and civil contracting company founded in 1993 and incorporated in its current form as DEMEX Pty Ltd in 2019. The company delivers complex, high-risk decommissioning and demolition projects across all Australian states and territories, serving industrial, infrastructure, mining/resources, government/defence, marine, urban & commercial development, education and health sectors. Its service portfolio covers demolition (decommissioning, demolition consulting, high-reach, industrial, mine-site, bridge), remediation (hazardous materials and asbestos removal, contaminated site remediation) and civil contracting (bulk and detailed excavation, mobile crushing, site preparation), sold primarily on a project-based B2B contract model as both principal contractor and subcontractor through tenders and government procurement portals.

The company's core technology is a specialist equipment fleet and proprietary engineering methods rather than a software platform: high-reach excavators, the Brokk 200 remote-controlled demolition robot, custom-engineered suspended platforms, a submersible diamond wire saw for large-diameter concrete piers, and environmental protection systems including multi-layered floating blankets and a crocodile-dive enclosure for marine pile cutting. Go-to-market is sales-led direct engagement, supplemented by government procurement registrations (QLD PQC Level 3, NSW buy.nsw, Federal Safety Accreditation FSC 598), industry association memberships (Austmine, CODA) and content marketing through the demex.com.au website, capability statements, project case studies and recurring award recognition (World Demolition Awards, Australian Workplace Health & Safety Awards). The company reports 90%+ on-site recycling on most projects, up to 99% in some cases, and is privately held with no disclosed parent company, investors or external funding.
