ABSTRACT:
An end cap is disclosed for terminating the end of a joint cover for sealing an elongated expansion joint between adjacent dynamic structures in such a manner as to permit movement of the joint while sealing the end of the joint against water and debris. The end cap includes an elongated convex elastomeric cover having portions thereon attached to each of the adjacent dynamic structures such that the convex cover spans the expansion joint between the adjacent structures to seal the joint. The end cap further comprises a transverse end wall member transverse to the direction of elongation of the expansion joint. The transverse wall member has at least one pleat formed therein transverse to the direction of movement of the joint, such that the transverse wall member folds and unfolds along the pleat as the expansion joint closes and opens.
