Protect your insulated systems from environmental damage while ensuring optimal performance and regulatory compliance.
For over 26 years since 1999, Caledonia Group has delivered comprehensive lagging services to leading industrial clients across the Northern Territory.
Our expert lagging solutions provide durable, weather-resistant protection for insulated systems, safeguarding your critical infrastructure from environmental damage, mechanical impact, and corrosion whilst ensuring optimal performance and compliance.


















Caledonia were chosen based on cost, site experience, previous performance and their ability to mobilise experienced personnel quickly. Their scaffolding builds are exceptional, and we’ve never been disappointed with what we’ve asked for or how urgently we’ve needed it built. The standard of scaffolding on this site has never been a question. All scaffolds were built in time during the shutdown, and no safety incidents were recorded.
