TRAINING.

Overview

By the end of this course, you will be able to:

• Diagnose deterioration mechanisms in concrete structures using visual and advanced testing methods
• Select and interpret appropriate inspection and non‑destructive testing techniques to support sound engineering judgment
• Assess structural condition, durability, and remaining service life to inform repair, rehabilitation, or replacement decisions
• Develop practical, cost‑effective concrete repair and rehabilitation strategies aligned with applicable standards
• Evaluate repair materials and techniques to improve long‑term performance and durability of concrete structures

Description

Concrete structures play a critical role in the built environment, yet many are affected by deterioration mechanisms that are not always visible or well understood. Decisions related to inspection, rehabilitation, or replacement often must be made with incomplete information, time constraints, and competing technical and economic considerations. Relying solely on visual inspection or prescriptive solutions can result in ineffective repairs, increased risk, or premature failure.

This course provides a structured, practical approach to evaluating existing concrete structures, identifying the underlying causes of deterioration, and selecting appropriate inspection, testing, and repair strategies. You will examine common degradation mechanisms such as corrosion, environmental attack, cracking, and material incompatibility, and learn how these issues influence durability, safety, and lifecycle performance.

Through real‑world case studies, proven methodologies, and current industry practices, you will develop the capability to assess condition and risk, interpret test data, and make informed decisions regarding concrete repair and rehabilitation. The course emphasizes practical application, helping you determine when repair is appropriate, how to optimize restoration strategies, and when replacement can be avoided.
