This updated and revised guideline will assist contractors, NDE service providers, owners, design professionals, and material suppliers in the selection of nondestructive evaluation (NDE) methods for evaluating the condition of concrete structures. NDE methods can be very useful to perform a condition assessment prior to repairs and to provide quality control and assurance of repairs and long-term performance monitoring. Considerations in planning and executing an NDE program, including correlating with destructive methods, are discussed in the guideline. Guidance, including a brief synopsis of each method, is presented for selecting which NDE methods are appropriate for the concrete property/condition being assessed.
This guideline is intended to provide information on electrochemical techniques used to mitigate the corrosion of steel in atmospherically exposed concrete structures. The information presented is based on testing and the experience of owners, engineers, contractors, and suppliers. This guideline includes information on impressed current and galvanic cathodic protection, electrochemical chloride extraction, and realkalization.

This guideline provides information on the properties and characteristics of grout materials for selection of a proper grout material to control water leakage through cracks and other discontinuities in concrete structures. It is also for the selection of grout materials for crack injection to control leaks through cracks in concrete structures. (formerly no. 03738).
Familiarity with contract types, the selection of appropriate repair work items, and documentation of completed work is essential for successful completion of a concrete repair project.This guide is intended to assist owners, consultants, and contractors in defining recommended methods of quantity measurement and contract types for concrete repair work.

Short Description:
Este Lineamiento pretende ser una herramienta usada para educar a supervisores, trabajadores del oficio, propietarios e ingenieros sobre las prácticas de trabajo seguras en la industria de reparación de concreto. El lineamiento se ha desarrollado para ser una herramienta visual que representa el desempeño seguro de tareas específicas y los peligros asociados con ellas. Los requerimientos descritos aquí se basan en los estándares de OSHA más recientes y pretenden proporcionar una guía y capacitación en la planeación y ejecución de proyectos de reparación y restauración.
This guideline is intended to assist the contractor, licensed design professional, and owner in the development of performance specifications for quality assurance and quality control of epoxy injection of concrete cracks. It includes process-control methods to assess if satisfactory injection work is being performed. Quality assurance methods described include visual observations and testing samples during the injection work, and removing concrete core samples and performing nondestructive testing of completed repairs.
This guideline is intended to assist architects, engineers, owners and their agents, developers, general contractors, and flooring contractors who are accountable for the successful installation of a floor covering or coating over an interior concrete sub-floor that is on, below, or above grade. This guideline provides information regarding moisture issues, moisture testing methods, interpretation of test results, and moisture mitigation strategies. The information provided in the guideline is meant to assist in the successful installation of floor coverings and coatings.
Provides information and guidance for the selection, evaluation, and use of surface applied corrosion inhibitors (SACI) for corrosion mitigation and supplement sound judgement by engineers, consultants, or others specializing in the repair of reinforced concrete structures experiencing corrosion induced damage. Understanding the existing concrete conditions and corrosion levels in the structure, the function and limitations of SACI materials, requirements for proper application and quality assurance/control during application, and evaluation and monitoring the performance are addressed.
An aid for the selection process, this guideline describes several methods of strengthening structures including externally bonded systems, post-tensioning, section enlargement and supplemental supports (formerly no. 03742).
