SISTAM is the first advanced and transportable NDT system for deep inspection aimed at detecting corrosion in civil infrastructures. It employs an innovative, distinctive, and non-invasive technique that enables the detection of corrosion processes in reinforced concrete structures at great depth. It delivers accurate and reliable diagnostics, invisible to other technologies, with a significant impact on maintenance and conservation operations. SISTAM will support public authorities managing critical infrastructures, operators, construction companies, concessionaires, and engineering firms in optimizing their operations, while reducing maintenance, conservation, and rehabilitation costs. With a focus on intelligent and sustainable maintenance, SISTAM will contribute to safer, more sustainable, and longer-lasting transport infrastructures, extending the service life of bridges and viaducts.
