Abstract
In the current practice of using an extruded elastomeric strip as a seal in a concrete expansion joint, in which the transverse walls more particularly are embodied with a chevron shape, the improvement thereto consisting of making the angled walls of the chevron steeper and spaced more centrally thereof, so that the seal both maintains continuous contact with the vertical faces of the expansion joint and also has a predictably consistent response to compressive forces.
