A tool to help designers, specifiers, contractors, and manufacturers make the best possible decisions in selecting materials for the repair of concrete surfaces. It fully describes a process used to develop sound selection criteria that will ensure that, for each project, the material properties needed to produce durable repairs are specified.

Short Description:
This guideline can be used to educate supervisors, craft workers, owners, and engineers in safe work practices for the concrete repair industry. The guideline will have universal appeal, as it has been developed to be a visual tool that depicts the safe performance of specific tasks and the hazards associated with those tasks. The requirements described are based on the most recent OSHA standards and are intended to provide guidance and training in the planning and execution of repair and restoration projects.
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 bundle includes the 110.1 (2016), 110.2 (2020), 110.3 (2021). 330.2 (2016) Guide Specifications. The documents cover Guide Specifications for Structural Concrete Repair, Epoxy Injection, Guide Specifications for Cementitious Bonded Overlay, and Externally Bonded FRP Fabric Systems for Strengthening Concrete Structures, respectively.
This guideline will assist contractors, owners, engineers, architects, and material suppliers in the selection of nondestructive evaluation (NDE) methods for evaluating the condition of concrete structures. NDE can be a very useful method 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 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.
Illustrates and describes the application methods commonly used for placement of concrete repair materials, along with material requirements, the best applications, and cautions and limitations for each. In addition, engineering considerations, surface preparation, constructability, environmental factors, quality assurance/control, and safety are addressed.
Moisture accumulation and water leakage into retail, commercial, and residential habitable spaces, including industrial facilities and below-grade parking structures, is the number one construction defect claim in our industry. The entire building envelope is a moisture barrier. Below-grade moisture barriers are required to keep water from leaking “into” and/or “out from” the structure. Water leakage inflow or outflow, and moisture accumulation within, can lead to health, safety and environmental issues involving the cost of operations and facility maintenance. Active water leakage, intermittent wetness, cavity wall moisture accumulation, and vapor transmission, can lead to costly problems: mold and mildew development, corrosion, contaminated water clean-up and disposal, slippery surfaces, and property damage.
Moisture-related problems with floor coverings and coatings are a serious and costly issue. Each year the direct and in-direct costs associated with such problems amount to billions of unplanned dollars. In this 5-part webinar series, experts in the field of moisture in concrete, testing, mitigation and repair will share information and experience in a ground up approach to the causes and solutions to such problems. The program covers the sources of moisture in concrete, the affect moisture has on slab behavior and the installation of flooring materials, the test methods used to properly assess slab moisture condition, moisture mitigation strategies, and more.
This demonstration will highlight the successful renovation of a concrete floor at the Flatstick Pub in downtown Spokane, Washington. The application of a self-levelling, polishable cementitious topping will be shown and the benefits of topping versus complete tear-out of the floor will be described.
