Our in-depth Grouting and Reinforcing Masonry Training (GRMT) gives BAC craftworkers practical knowledge of code compliant procedures and industry standards to reinforce and grout masonry wall systems.
If you want to be sure the masonry craftworkers on your project are trained under GRMT to properly grout and reinforce masonry, use our sample specification language.
GRMT is a program covering the role of masonry craftworkers in the overall execution of reinforcing and grouting masonry wall systems, including an in depth understanding of materials, placement methods, testing and inspections in masonry construction. The learning modules actively engage masonry craftworkers – through lecture, discussions and hands-on training sessions lead by experienced IMI and IMTEF instructors. The course also draws on assistance and participation from building owners, members of the architectural design community, members of the architectural design community, and product manufacturers.
Students learn the importance of properly installed reinforcements in structural and non-structural masonry.
This module discusses the holistic behavior of building structures, including load pathways and what types of loading is typically considered in structural design. The discussion transitions to how masonry systems function within a structural system, highlighting masonry’s capacity to resist compressive forces and the reasoning behind reinforcing bars (rebar) and grout. Students gain a more in-depth understanding on how masonry responds to loading within plane walls as well as around openings, including a review of available unit shapes and lintel/bond beam requirements.
In this module, craftworkers get an overview of the various codes and standards that are most applicable to grouting and reinforcing masonry. A review of TMS 602 Mandatory and Optional Specification Checklists helps students to know what to expect when reviewing construction documents. Participants are also exposed to ASTM Standards that regulate various materials, testing methods (including who should perform certain tasks), and delivery methods.
This module introduces students to the types of problems that may arise during any grouting or reinforcing procedure, as well as appropriate testing and remediation work required. Typical sources of various problems are discussed as well as ways to avoid potential issues.
This module provides an overview of the most typical reinforcement used in masonry construction. Reinforcing bar (rebar) identification, splices, couplers, and ties are discussed along with placement tolerances and positioners. Anchor bolts and joint reinforcement are also covered.
This module provides in-depth information pertinent to the grouting process. Students learn the importance of taking all the appropriate steps to ensure the grout makes full contact with the reinforcement and masonry.
This module emphasizes the importance of personal protective equipment and appropriate use of specialty equipment, tools, and procedures associated with the reinforcing and grouting process. Emphasis is given to protecting against exposure to hydrating cement in grout. Grout pumping, rebar placement, rebar capping safety, and limited access zones during construction are also addressed.
Students team up to build a reinforced masonry mockup in order to demonstrate an understanding of the requirements taught in the previous modules. The process generally includes the erection of masonry units and placement of rebar in one mockup, and the grouting of a second prebuilt mockup. Verbal interaction between students and instructors are important aspects that convey an understanding of materials taught throughout the program.
GRMT is offered in the following locations:
Design professionals and project owners can contact IMI for more information about the program or to access a list of qualified contractors in your area. BAC signatory contractors can also contact IMI for additional background or to inquire about employee certification.
BAC craftworkers should contact their local training center or coordinator to inquire about program availability. BAC Local Officers and Training Coordinators can contact IMTEF to enroll members or to get additional information about program availability at the International Training Center. To find out about upcoming classes at the BAC/IMI International Training Center, see the International Masonry Training and Education Foundation’s training calendar.
