Presented by Contech Services, Inc.

Pete Barlow—Vice President

A brief presentation of technologies available to replace and or supplement missing reinforcing steel in slabs and walls. Missing reinforcing steel can occur by field or detailing errors. Once the structural elements are cast, the application of external reinforcing may be a solution. Discussions on engineering properties and application procedures will be reviewed for the different technologies.


The concept of a building code for repair of existing concrete structures has been discussed for nearly thirty years. However, a major obstacle to the development of a concrete repair code was how it would interact with existing codes, such as ACI 318, the International Building Code (IBC), and the International Existing Building Code (IEBC). In June 2016, the American Concrete Institute published ACI 562-16, Code Requirements for Assessment, Repair and Rehabilitation of Existing Concrete Structures and Commentary. This code was developed to provide design professionals a code for the assessment of damage and deterioration of concrete structures, and the design of appropriate repair and rehabilitation strategies. ACI 562 includes both prescriptive and performance requirements, which provide great latitude and flexibility to the licensed design professional in satisfying the requirements of ACI 562. The presentation will describe the concrete repair code, focusing on how the code interacts with other codes and is to be used on concrete repair projects. Evaluation and analysis options will be discussed along with a worked example.

Benefits and knowledge our members can expect to take away from the presentation:

  • An introduction to ACI 562 code provisions

  • Learn how ACI 562 interacts with other codes to be used on concrete repair projects.

  • A worked example of the application of ACI 562 code provisions on a concrete repair project will provide insight on how the code is to be used in practice
