Detection At Its Finest.

Caledonia Group has been offering expert identification methods in corrosion under insulation monitoring for nearly a decade. Our highly skilled insulators work with our engineers and suppliers to incorporate components into our insulation systems that allow us to detect leaks and moisture within the insulation system. One method that Caledonia utilises to detect CUI is by carrying out thermographic inspections.



Caledonia has the expertise and knowledge in remediating corrosion under insulation. Sometimes asset owners are not able to detect CUI as quickly. Rest assured, we can drain the moisture using inspection hatches, drain plugs, flange belts, drains and collection glasses, polysurlyn coatings and hydrophobic insulation materials
