TECHNICAL ACTIVITIES COMMITTEE
Chair: Mark Nelson, Nelson Testing Laboratories
TAC recommends, implements, and oversees technical activities consistent with policies established by the ICRI Board of Directors. This includes monitoring and oversight of all technical activities for content, progress, and compliance with approved policies. Activities include production of guidelines and other documents for use by the concrete repair industry as the committee deems necessary and appropriate and oversight of convention technical sessions, including selection of speakers and session moderators.
A TAC subcommittee was appointed in 2014 to conduct a detailed review of the current document development process and propose revisions as appropriate for TAC consideration. As a result of this study, TAC has increased emphasis on development of technical offerings from technical committees other than printed media. These products include PPT presentations, videos, Webinars, guide specifications, and input for certification programs. A number of suggestions to streamline the overall production process have been adopted by the Strategic Implementation Committee.
- TAC-A Technical Programs
Chair: Peter Golter, 3M
This subcommittee is responsible for selection of presentations for technical sessions at each ICRI convention.
Chair: Jeffrey S. Barnes, Barnes Consulting Group, LLC
The Coordinating Committee roster includes officers of all ICRI technical and administrative committees (Chairs, Vice-chairs, subcommittee chairs or chair designated participants), Executive Committee members, Secretariat Members and TAC members. The objective of this committee is to facilitate harmonization of document development and the committee operation process between ICRI committees.
The Coordination Committee’s training breakfast meeting had 24 attendees at the Fall 2016 convention. The acting Chair, Mark Nelson, led a discussion of recent progress in implementation of the Strategic Plan. Four Secretariats (Mark Nelson, Rick Edelson, Bud Earley, and Jeff Barnes) have been selected to implement and oversee ICRI offerings from idea to finished product. An IDEA summary form for submittal of proposed project information was shown followed by discussion of how proposals are evaluated and processed. Dale Regnier discussed the current status and immediate plans for the Causeway website voting system and reported that he was currently concentrating on establishing correct rosters and transferring committee files for all technical committees.
The Coordination Committee’s Spring 2017 meeting had 22 attendees. Implementation of the Causeway Committee Management System was the primary topic for discussion. Dale Regnier reported that the Causeway site is functional for all technical committees and Committee pages have been populated with rosters and, except for TAC and Coordination, all committee files from the CAM website. Addition of administrative committees will begin following the convention.
The Causeway site is accessed through a link on the ICRI website. An effective training session on the use of the Causeway program, including information on; logging in, document storage, committee member maintenance, balloting, and other useful tips was provided by Causeway in December 20, 2017. This 1-hr session was recorded and viewing of the WebEx Video is highly recommended. Judging from the ensuing enthusiastic discussion, reactions to the potential for the Causeway system appeared to be very positive.
COMMITTEE 110 - GUIDE SPECIFICATIONS
Chair: Liying Jiang, Simpson Gumpertz & Heger, Inc.
The ICRI guide specification and commentary 110.1, “Guide Specifications for Structural Concrete Repairs,” was published in January 2016. The purpose of this guide specification is to aid the Design Professional in the preparation of technical specifications, for inclusion directly into contracts for construction of concrete repairs that are in line with the state-of-the-art materials and methods used in the concrete repair industry. Its primary focus is to provide an outline for developing the three parts of the specification through suggested text, references, and commentary for evaluating alternatives. The Committee also developed a PowerPoint presentation that describes the guide specification. Committee 110 is currently developing guide specifications for, “Epoxy Injection of Concrete Cracks,” and “Cementitious Bonded Overlays.”
COMMITTEE 120 - ENVIRONMENTAL HEALTH AND SAFETY
Chair: Paul Farrell, Carolina Restoration & Waterproofing, Inc., a C.A. Lindman Company
The committee continues to explore potential methods for improved marketing of Technical Guideline No. 120.1-2009, “Guidelines and Recommendations for Safety in the Concrete Repair Industry.” A presentation to introduce the Safety Guideline to ICRI chapters has been developed and is available for download and use by members HERE. A Spanish version of the guide was produced and introduced at World of Concrete 2013.A Task Group continues to make progress revising the original Guideline 120.1. Three White Papers developed by Committee 120 can be downloaded from the ICRI website Free Publications page.
The committee continues to draft content for “Safety Solutions,” a new column that was introduced in the Mar/Apr 2010 CRB. The committee is currently working with the Awards Committee to include a “Safety” element in documentation for project awards. Also, they are developing criteria for a “Safety Award” with a Fall 2017 goal for confirmation.
COMMITTEE 130 - PROCUREMENT METHODS AND RELATIONSHIP ARRANGEMENTS
Chairs: Jeffrey R. Carlson, Consulting Engineers Group, Inc. and Michael Saulnier, Pegasus Painting & Waterproofing
Guideline No. 130.1R, “Guide for Methods of Measurement and Contract Types for Concrete Repair Work,” was published in 2009. This guide is intended to assist owners, consultants, and contractors in defining recommended methods of quantity measurement and contract types for concrete repair work.
The committee is developing a procurement document to provide guidance to owners, designers, and contractors on ways to formalize agreements among themselves to design and/or perform restoration projects. The guideline will discuss responsibilities and liabilities of each member of the restoration team, give examples of different contracting methods, and establish an ICRI recommended process to serve as the industry standard.
ICRI 130.2, Guideline for Procurement of Concrete Repair Services,” has been reviewed by TAC and approved pending satisfactory compliance with review comments (Spring 2017). Once the committee has revised the document, it will be returned to TAC for a compliance check and publication.
COMMITTEE 160 - LIFE CYCLE AND SUSTAINABILITY
Chair: I-Wen Huang, BASF
Committee 160 drafted a chapter, “Sustainable Concrete Repairs,” included in the US Green Concrete Council’s book, “The Sustainable Concrete Guide – Applications.” A White Paper, “Sustainability for Repairing and Maintaining Concrete and Masonry Buildings,” was reviewed by TAC and approved for publication in April 2014. An Introduction to the White Paper was published in the Sept/Oct 2014 CRB. The entire White Paper can be downloaded from the Free Publications page.
The committee has also drafted guidance on how sustainability issues can be addressed in other ICRI technical documents and criteria for the Awards Committee to use in judging nominations for a Sustainability Award. Criteria for the Sustainability Award were approved and submitted for TAC review (Spring 2016). There were a number of questions about some criteria for the sustainability award, particularly carbon footprint, being available to those preparing nominations. The Committee160 Chair volunteered to lead further discussion of these questions with the 160 and Awards committee.
A draft document, “Guideline for Evaluating Concrete and Masonry Building for Sustainability,” was posted on the 160 website following the Fall 2013 meeting. Subsequent reviews indicated that division into two individual guidelines for concrete and masonry buildings was preferable. Consequently, separate document development requests were submitted to TAC and approved at the Spring 2014 meeting. The committee reported (Spring 2015) that progress is being made on both guidelines. The committee reported (Spring 2016) that sections from the Life Cycle report will be incorporated into the concrete sustainability document. Plans were to complete this document by the end of 2016. A PowerPoint presentation will also be created to lead the user through the process.
COMMITTEE 210 - EVALUATION
Chairs: Charles Mitchell, Smislova, Kehnemui & Associates, P.A. and David Rodler,Smislova, Kehnemui & Associates, P.A.
The committee reported (Fall 2015) that they planned to create an educational program based on Guideline 210.3R–2013, “Guide for Using In-Situ Tensile Pulloff Tests to Evaluate Bond of Concrete Surface Materials.” This video and “how to guide” will be a companion document to the existing guideline. A Document Development Request for a 1 to 2 hour web-based educational module for applications, testing, and interpretation of in-situ pull-off tests was submitted to TAC and approved at the Spring 2016 meeting. Committee 210 reported (Spring 2017) that work on format and content for the training webinar continues toward a goal to ballot by May 2017.
A task group was developed (Fall 2016) for investigating educational materials from extra technical content that was prepared as part of the surface repair technician certification program. A conference call will be held after the convention to further develop this effort. In addition, a task group was formed (Spring 2017) to explore development of potential products (rebar samples, photos, etc.) that could be used to illustrate the various stages of reinforcing steel corrosion, cleanliness, etc.
Guideline 210.4-2009, “NDE Methods for Condition Assessment, Repair, and Performance Monitoring of Structures,” has been reviewed and revised. Proposed changes will be reviewed by key personnel in the testing industry prior to an anticipated ballot in April 2017.
COMMITTEE - 310 SURFACE PREPARATION
Chair: Pete Haveron, Texas Concrete Restoration Inc.
Guideline 310.1R-2008, “Guide for Surface Preparation for the Repair of Deteriorated Concrete Resulting from Reinforcing Steel Corrosion,” was published in March 2009. A Task Group was formed at the Fall 2015 meeting to revise Guideline 310.1R. The revision is continuing with current to include a PPT presentation with 10-15 questions that could be used for continuing education credit. There are similar plans for Guidelines 310.2 and 310.3. The revised Guideline 310.3R, “Preparation of Concrete Surfaces for Repair Using Hydrodemolition Method,” was published in June 2014.
COMMITTEE 320 - CONCRETE REPAIR MATERIALS AND METHODS

Chair: Peter Kolf, CTLGroup
The revised Guideline 320.1R-1996, "Selecting Application Methods for the Repair of Concrete Surfaces," was approved by TAC pending satisfactory compliance with review comments (Fall 2014). Committee 320 then proposed to update selected sections of the document in accordance with TAC comments and submit for a preliminary TAC review (June 2015) before proceeding with the entire document. Based on a preliminary review of three sections (September 2015), TAC concluded that the revised format was acceptable pending consideration of review comments. Current plans are to update the remaining sections, including photos and graphics, and submit for 320 ballot by June 2017.
- 320-B Materials for Concrete Surface Repair
Chair: Ashish Dubey, PhD, FACI, USG Corporation
Guideline No. 320.2R-2009 (formerly 03733), “Selecting and Specifying Materials for the Repair of Concrete Surfaces,” was successfully balloted in March 2014 with 4 negative votes to be resolved. The document was revised based on comments from the previous review and successfully balloted in January 2015. The revised guideline was submitted for TAC review June 2015. TAC approved pending compliance with review comments October 2015. The revised draft was checked for compliance by TAC and approved document was submitted to staff for publication Nov 2016. ICRI staff has requested color photographs. The goal is to publish the guideline before the Fall 2017 Convention.
- 320-C Grout Material Data Sheet Protocol
Chair: Aamer Syed, Sika Corporation
The “Guideline Structural Grouts Material Data Sheet Protocol” was submitted for TAC review in January 2014. TAC returned the document to Committee 320 for revision, reballot, and resubmittal to TAC. The revised document was successfully balloted September 2015 and submitted for TAC review March 2016. TAC approved the document, pending satisfactory compliance with review comments, Sep 2016. Current plans are to update the document to address the TAC review comments and submit for 320 approval ballot by June 2017.
- 320-D Pictorial Atlas of Concrete Repair Equipment
Chair: Kevin Robertson, King Construction Products
Guideline 320.5R-2014, “Pictorial Atlas of Concrete Repair Equipment,” was revised to include a section on finishing and hand tools, approved by TAC, and published in May 2014. The committee is currently collecting information on other types of equipment (i.e. pumps, shotcrete equipment, slab jacking equipment) to expand the guideline. Current plans are to expand the pictorial guide to include a new chapter on pumps and shotcrete equipment by Nov 2017.
A Committee 320 request to develop a guideline, “Concrete Cracks - Identification, Cause, Prevention, and Repair,” was approved by TAC at the Fall 2014 meeting. TAC emphasized that the committee concentrate on development of a document that will educate users in evaluation of potential causes of cracks based on physical appearance, location, size, etc. Plans were to base this educational/training tool on courseware provided to the committee by Simpson Strong-Tie. TAC reviewed the craze cracking module and endorsed the concept and format (Spring 2016). TAC also noted that this effort should be coordinated with Administrative Committees, including Education, Marketing, and Finance for assistance in their areas of expertise.
A Go To Market Form was recently submitted to ICRI. Also, an IDEA Form was submitted to ICRI Secretariat. A task group was formed to develop technical content for five (5) individual crack modules and assigned all other modules to members for preparation of technical content (PowerPoint). Plans are to submit the initial 5 modules for TAC preliminary approval in July 2017.
COMMITTEE 330 - STRENGTHENING AND STABILIZATION
Chair: Tarek Alkhrdaji, Structural Technologies
Guideline No. 330.1-2006, “Selection of Strengthening Systems for Concrete Structures,” was reapproved in 2012. It was noted (Spring 2016) that the document should be revised to include fiber-reinforced cementitious materials (FRCM); however, a schedule for revision has not been established. Instead, the committee has concentrated on drafting a guide specification and commentary for externally bonded FRP fabric systems for strengthening concrete structures.
TAC approved the specification pending satisfactory compliance with review comments at the Fall 2014 meeting. The revised draft was submitted to TAC (December 2015) to determine compliance with review comments. Following format changes, ICRI 330.2, “Guide Specifications for Externally Bonded FRP Fabric Systems,” was forwarded to staff (March 2016).for final edit and publication (October 2016). Future plans include development of additional guide specs for FRP laminates and FRP NSM.
A review of a draft outline for a FRP Applicator Certification Program (Spring 2015) generated significant discussion, questions, comments, and concerns. A revised outline was successfully balloted September 2015. Work assignments were made for committee members to supply slides/videos, etc., for the technical content of the certification program (Spring 2016). Based on discussions at the Spring 2017 Committee 330 meeting, it was decided to replace “Applicator” with “Inspector” in the title of the certification program. A revised outline and content requirements for the FRP Inspector Certification program was submitted for TAC review in April 2017.
COMMITTEE 410 - MASONRY
Chair: Jason Coleman, O'Donnell & Nacarrato, Inc.
Guideline No. 410.1-2008, “Guide for the Evaluation of Masonry Facade Structures,” was released in March 2009. This guideline describes the tools, techniques, and processes that are used in the evaluation of masonry facade structures.
Following publication of the evaluation document, the committee began drafting a guideline for repair and strengthening of masonry facade structures. Reportedly, a committee ballot of the repair guideline was initiated with a closure date of Dec 12, 2013; however, no results were reported to TAC. This effort remained inactive until the Spring 2017 meeting when the current committee leadership decided to explore completion of the guideline and requested a current copy of the draft document along with any available TAC comments.
New committee topics and goals were discussed at the Fall 2014 meeting and the committee proposed development of a series of “Practice Guides.” A document development request, “Practice Guide: In-place Stabilization of Terra Cotta,” was submitted to TAC and approved at the Fall 2014 meeting. TAC advised that the guide should emphasize “how to use” appropriate stabilization techniques and detailed technical background on procedures should be minimized or avoided.
Recent committee meetings and interim virtual meetings have been devoted to development, review, and editing of the Practice Guide. Currently, the guide is approximately 85% complete and scheduled for completion by the Fall 2017 convention.
COMMITTEE 510 - CORROSION
Chair: Jorge Costa, Durability, Inc.
A request for development of a “Guide for Conducting Half-Cell Potential, Corrosion Rate, and Resistivity Testing for Steel Reinforced Concrete Structures” was reviewed and approved by TAC at the Fall 2014 meeting. Recent committee meetings at conventions and interim virtual meetings have been used to draft and review sections of the guideline. Current plans are to complete and ballot the guide by the Fall 2017 convention. The committee also plans to develop presentation(s) to introduce the guide/testing techniques.
- 510-A Electrochemical Techniques for Corrosion Mitigation in Concrete Structures
Chair: David Whitmore, Vector Corrosion Technologies
Guideline 510.1, "Electrochemical Techniques to Mitigate the Corrosion of Steel for Reinforced Concrete Structures,” was approved by TAC in January 2013 and published in June 2013.
- 510-B Corrosion Inhibitors
Chair: Tim Gillespie, Sika Corporation
Guideline No. 510.2, ‘Use of Penetrating Surface Treatments for Corrosion Mitigation of Reinforced Concrete Structures,” was submitted for TAC review at the Spring 2015 meeting. The TAC Review Group recommendation to approve the document pending satisfactory compliance with review comments was approved by TAC. Responses to TAC review comments were completed and approved by Spring 2016 committee meeting ballot. The document was revised in response to review comments and was submitted to TAC Aug 2016 for a compliance check. Upon receipt of the additional information requested, the document was deemed to be in compliance with TAC review comments and the approved draft was submitted to staff Nov 2016 for publication. Images requested by staff will be provided by committee by the end of Mar 2017, with publication of the document shortly thereafter. Committee 510 submitted a Document Development Request for a PowerPoint presentation describing the corrosion inhibitor guideline for TAC consideration and approval at the Fall 2016 meeting.
COMMITTEE 710 - COATINGS AND WATERPROOFING
Chair: Mark Nelson, Nelson Testing Laboratories
- 710-A Horizontal Waterproofing of Traffic Surfaces
Chair: Kevin Buck, Huntsman
Guideline 710.2-2014, “Guide for Horizontal Waterproofing of Traffic Surfaces,” was published in October 2014.
- 710-B Moisture-Related Issues with Concrete Floor Finishes
Chair: Lee Eliseian, Independent Floor Testing and Inspection
The draft Guideline, “Moisture-Related Issues with Concrete Floor Finishes,” was submitted to Committee 710 for ballot in March 2014. The ballot was unsuccessful because at least 1/2 of all voting members on the committee roster did not cast an affirmative vote. A new subcommittee ballot was initiated with a Dec 1, 2015 closure. Enough votes were received to make this a valid ballot. Unfortunately, results of this ballot (list of voters, comments, etc.) were apparently lost in the website transition to Ewald. After the balloting issue was resolved, the document was reballoted Feb/Mar 2017. This ballot was unsuccessful because of negative votes that must be resolved.
- 710-D Polymer Flooring Systems
Chair: Tom Murphy, Adhesives Technology Corp.
Guideline No. 710.1-2004, “Design, Installation, and Maintenance of Protective Flooring Systems,” was published as a joint document with NACE and SSPC. The Guideline contains detailed information on the aspects of flooring technology, performance properties, surface preparation requirements, installation procedures, and testing to help the user attain long-term service from a variety of polymer flooring systems in a wide range of applications.
A signed MOU was executed with SSPC/NACE in November 2014 for joint participation in updating Guideline 710.1. A number of conference calls and meetings since then have resulted in a draft to be balloted by ICRI (April 2017) and SSPC and NACE (Summer 2017). If approved by all parties, the document will be forwarded to TAC by the end of summer (2017).
- 710-E Grouting
Chair: David Dorsch
The Grouting Task Group produced Guideline No. 340.1, “Guide for the Selection of Grouts to Control Leakage in Concrete Structures,” in 2006. TAC disbanded the Task Group when ICRI adopted the current Committee structure and transferred responsibility for document maintenance to Committee 710 (Spring 2014) that Committee 710 initiate a ballot to reapprove this document, then begin a revision as appropriate. The committee reported (Fall 2014) that a subcommittee has been formed to revise the document.
Reportedly (Spring 2015) the document has significant deficiencies and should be completely rewritten. Also, the subcommittee proposes to revise the title to “Nonstructural Grouting for Leaking Structures.” Multiple conference calls have been used in the revision and others are tentatively scheduled to complete revision, address committee ballot comments, and TAC review comments. The subcommittee plans to complete the revision by June 2017 and initiate a ballot at that time. If successful, the document will be submitted for TAC review by the end of summer.
