Abstract
An expansion joint and seal for an expansion joint for use in structures where the joint has an intersection uses a seal with a solid thick keel extending along a lower edge of a central portion in an area of the intersection. The keel commences in a transition area between a conventional seal and the intersection. The seal increases in depth as the intersection is approached until it reaches a maximum depth at a mid point of the intersection. The keel minimizes distortion from racking during expansion or contraction of the joint. The seal is shaped to enable debris to be easily removed.
