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.
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 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.
The intent of this document is to provide objective, standards-based comparison for the
specification, evaluation, and approval of the degree of surface preparation of exposed
conventional reinforcing steel by abrasive media blasting and mechanical hand tool methods.
This guide is designed for use with associated illustrative materials available in digital or
physical form through ICRI.
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)]
Summarizes the capabilities, operating requirements, and limitations of the various methods used to prepare concrete surfaces for the application of protective sealers, coatings, polymer overlays, and concrete repair. Benchmark profiles are included which provide visual standards for purposes of specification, application, and verification. In this updated version of the guideline you will find; surface retarders and handheld breakers have been added to the surface preparation methods; surface preparation methods have been updated; and a new appendix summarizes considerations for selecting surface preparation methods and describes various test methods used to evaluate the prepared surface. Plus, concrete surface profile (CSP) 10 has been added to reflect a more aggressive CSP used for concrete repair.
This comprehensive book describes the causes, effects, and remedies for concrete wear and failure. It is a practical guide to evaluation of deterioration and its causes, selection of repair methods and materials, surface preparation, and quality assurance of the finished product. Hundreds of illustrations show users how to analyze, maintain, and repair concrete structures for optimal performance and cost-effectiveness.
This guide specification aids the Design Professional in the preparation of technical specifications for inclusion directly into a project manual for the construction of cementitious bonded overlays that are in line with the state-of-the-art materials and methods used in the concrete repair industry. The document provides an outline for developing the three parts of the specification through suggested text, references, and commentary for evaluating alternatives. This specification section must be used with ICRI 110.1, Guide Specifications for Structural Concrete Repairs. Both the printed and PDF copies include a Word document with hidden text for easy modification of text to meet specific cementitious bonded overlay project requirements. PDF version is free to ICRI members when ordered online.
