Masonry Movement Joints - 1 LU/HSW

Tuesday, November 2, 2021 | 12:00 - 1:00 p.m. Eastern Daylight Time

Presented by: IMI

Explore the movement characteristics of various types of masonry and how to successfully accommodate those movements for a crack-free building. We'll analyze the different sources of building movement including a material’s temperature changes, moisture changes, and deflection of building elements. Review industry guidelines for location, spacing, and width of movement joints. You'll learn how to handle both vertical and horizontal movements, including the detailing of flashing and other elements that may be required. Finally, we'll discuss building code requirements for showing movement joints on the construction drawings.
 Learning Objectives:
  • Understand the difference among the often confused terms “movement joint,” “expansion joint,” and “control joint,” and be able to use these terms in correct context on project documents.

  • Learn all the typical conditions of a masonry building that require movement joints in order to prevent cracking and become familiar with concepts that dictate typical locations and spacing.

  • Understand building code requirements for the type of information describing the movement joints required to be shown on the construction documents.

  • View case studies of cracked walls and other failures, diagnose their causes, and learn how the proper detailing for movement may have prevented the cracking.
