Building movement will happen whether or not we want it to. If we do not account for where movement will occur during design and construction, the building will find its own way to move. This course will cover why building movement joints are needed, the differences between various types of joints, how expansion joints should provide continuity of the air and water control layers, as well as samples of what failures can occur. We will also review a case study showing failures which can happen when expansion joints are not designed and installed.
Learning Objectives:
- Review best practices for the location of expansion joints on building enclosures.
- Identify the difference between expansion, control, and isolation joints.
- Investigate building failures caused by poor expansion joint design and lack thereof, and premature failure due to improper installation.
- Cover the causes of sealant failure, the importance of proper joint design and how it can dictate performance.
