Expansion Joints--Terms and Terminology:

Adhesion In Tension--In principle, the weakest way to use an adhesive, yet the principle on which many expansion joint and sealant technologies rely for their performance.  Adhesives are best used in shear.  The more durable joint sealing technologies rely either on adhesives in shear as in "membrane/nosing" type products, or use inherent compression to diminish or eliminate adhesion in tension on the bond line as well as within the sealant or adhesive material itself.


NOTE: The definitions of terms and terminology herein are rooted in the context of use in the field of construction-related joint sealing in EMSEAL's experience.  They are provided with the intent of offering a fuller understanding of the context of their usage.
