Abstract
An expansion joint system includes: a core; and a layer of an elastomer disposed on the core. The core and the layer of elastomer disposed thereon form an elongated section, the elongated section configured to be oriented vertically between substantially coplanar substrates. The expansion joint system further includes a termination section located at one end of the elongated section and comprising a flared end forming an angle with the elongated section and configured to direct fluid and/or particles and/or solvents away from the expansion joint system.
