What defines a compression joint seal?

A compression joint seal is defined as a rectangle of neoprene with a honeycomb cross-section. This design allows for flexibility and durability, enabling it to effectively manage the movement between two bridge elements. The honeycomb structure provides strength while maintaining the ability to compress and expand under pressure, responding well to thermal expansion and contraction, as well as to the dynamic loads experienced by bridges.

The use of neoprene material enhances its weather resistance and longevity, making it suitable for outdoor applications where exposure to the elements is significant. This kind of seal is typically utilized in bridge expansion joints to prevent water and debris from entering the joint while accommodating the necessary movement between structural components.
