Introduction
Existing concrete structures are continuously exposed to environmental, operational, and structural conditions that may lead to deterioration, cracking, corrosion, loss of durability, and reduction in structural performance. Effective assessment and timely repair are therefore essential to maintain structural safety, functionality, and service life.
This comprehensive five-day training course provides Civil and Structural Engineers with a practical and systematic approach to the inspection, assessment, diagnosis, repair, rehabilitation, and strengthening of existing concrete structures.
Throughout the training, participants will explore common deterioration mechanisms, structural defects, inspection procedures, Non-Destructive Testing (NDT), reinforcement corrosion, concrete condition assessment, repair materials, repair techniques, and strengthening methods. The course emphasizes the relationship between inspection, diagnosis, and the selection of appropriate repair solutions.
The course combines technical knowledge with practical examples, case studies, defect identification exercises, and repair strategy development to support participants in making sound engineering decisions.
