NDT, Corrosion,CUI,Inspection InspecTerra's patented iCAMMTM inspection system is used to non-destructively quantify and map the degree of corrosion and defects in critical structural elements (e.g., steel members and reinforcing steel). The method is passive and not impacted by environmental conditions, such as salt and moisture. The iCAMMTM tool has been used to inspect embedded reinforcing steel in various structures, including bridges, dams, and parking garages. It has also been used to rapidly map the corrosion in steel structures and detect external and internal flaws in railway tracks.
