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 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.
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.
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 guideline is intended to provide information for the selection and application of materials
for fluid-applied waterproofing systems to concrete for horizontal pedestrian and vehicular
traffic surfaces.
Concrete is subject to deterioration by a variety of mechanisms. Properly selected and applied
traffic membrane systems can protect concrete from deterioration caused by abrasion, moisture
intrusion, environmental forces (freezing-and-thawing cycling), and chemical attack. This
guideline provides information on the common service conditions, basic review of the properties
of concrete, surface preparation, system designs, and materials used for traffic membranes.
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).
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.
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.
Outlines the steps in preparing concrete for replacement material in areas where corroded reinforcing steel has caused cracking, spalling, delamination, or other types of deterioration. Topics covered include exposing and undercutting reinforcing steel, edge and surface conditioning, repair of reinforcing steel, and removal geometry.
