Session Overview: 

Cracking in concrete is inevitable. Control, construction, and expansion joints are intentionally designed into concrete structures and flatwork to accommodate drying shrinkage, thermal movement, and differential movement between adjacent elements. Even with these preventative measures, concrete can experience cracking; moreover, repairs in concrete structures also suffer from cracking. This webinar will review the causes for cracking in concrete and the standard, preventative methods for addressing movement. We will build on this to gain an appreciation for identifying the root causes of cracking to ensure effective repair strategies can be developed to arrive at sustainable, long-lasting solutions.

Learning Objectives:

  1. Develop an understanding of the cracking that occurs in concrete structures and flatwork.
  2. Gain an appreciation of identifying the root causes for cracking.
  3. Identify various types of cracks in concrete and concrete repairs.
  4. Learn how to develop an effective, sustainable strategy for repairing cracks.
