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 is the initial document in a series of guide specifications to be prepared by ICRI. The guide specification offers a methodology for standardizing the essential requirements for structural concrete repairs by providing specification text, optional requirements, and commentary to allow the user to tailor the document to a specific concrete repair project, and use as a technical specification section in a complete project manual. Both the printed and PDF copies include a Word document with hidden text for easy modification of text to meet specific repair project requirements.
This guide provides a recommended method of evaluating the adequacy of concrete surface preparation and tensile bond strength of cementitious and polymer concrete surface repairs using the in-situ drilled core tensile pulloff test. The guide outlines equipment and material requirements, the test procedure, reporting, and acceptance criteria. This update also includes failure modes for concrete substrate tests.

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 provide an introduction to hydrodemolition for concrete removal and surface preparation, the benefits and limitations of using hydrodemolition, and an understanding of other aspects to be addressed when incorporating hydrodemolition into a repair project. The guideline provides a description of the equipment, applications, safety procedures, and methods of water control and cleanup.
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.
This option is available for those who purchased the Certification course and completed the training Modules 1-5 and the knowledge exam — but failed one or more of the tests in the performance exam.

This guide is intended to provide an introduction to the techniques and procedures used to evaluate and repair existing concrete structures post-tensioned with unbonded single-strand tendons. This guide demonstrates how the strength and serviceability of a structure that has experienced deterioration can be evaluated and restored to its original—or greater—strength and serviceability. Post-tensioning design, evaluation, and repair requires specialized knowledge. There is no substitute for experience and knowledge in working with post-tensioned structures. An experienced contractor and licensed design professional team is essential when working with post-tensioned structures. [Replaces 210.2–2002 (Evaluation) AND 320.4–2006 (Repair)]
La preparación correcta de la superficie es un elemento clave para determinar el éxito de un proyecto de restaura-ción de concreto. La preparación inadecuada de la super-ficie puede llevar a la falla del sistema de protección o material de reparación, que resulta en mayores repara-ciones, gastos agregados y pérdida de uso, y puede en último término comprometer la integridad de la estructura. La preparación de la superficie es el proceso por el cual una superficie sana, limpia y adecuadamente raspada se produce sobre un sustrato de concreto. La preparación de la superficie incluye la remoción de lechada, suciedad, aceite, capas, pintura, recubrimientos, concreto sano o en mal estado y otros materiales que interferirán con la ad hesión o penetración de un sellador, recubrimiento, revestimiento de polímeros o material de reparación.
