It is also known as a movement joint, which is an assembly consisting of separation in the wall a flexible material like a bond breaker or sealant. Bond breaker materials may comprise of sprays, liquids, rods, or tapes. They are required for breaking the bond between building sections for ensuring the sections can separate. The material being compressible, it can accommodate the movement of adjacent materials. For closing the joint opening and mitigating moisture from entering the joint, a flexible sealant is applied along with accommodating movement between wall sections. When performing a building envelope survey, all of these factors must be taken into account.
