The purpose of a masonry control joint is to allow free movement while maintaining the weathertightness of the construction.
Brick wall expansion joint.
This allowed movement helps prevent distortion and cracking.
Cracks in brick walls.
Expansion control joints to control the expansion and protect the wall structure from cracking under pressure masons install vertical control joints at specific locations.
In the past when cmu and brick walls were constructed as bonded composite walls control joints and expansion joints needed to be coordinated and aligned through both the block and brick.
Accommodate these movements with a series of expansion joints.
Of expansion joints can be applicable to all structures.
Foundations how to recognize diagnose repair or prevent brick wall or foundation cracks due to thermal expansion factors that determine the extent of thermal expansion damage to a brick wall or structure absence of control joints or expansion joints in long brick walls leads to extensive cracking damage photographs of foundation damage patterns and types of.
Review each structure for the extent of movements expected.
An information series from the national authority on concrete masonry technology ncma tek 10 2c 1 control joints for concrete masonry walls empirical method introduction concrete masonry is a popular construction material because its inherent attributes satisfy the diverse needs of both exterior and interior walls.
Determine the spacing of expansion joints by considering the amount of expected wall movement the size of the expansion joint and the.
While these attributes are the primary basis for concrete masonry s.
