Abstract
An expansion joint system for a wall is provided herein wherein a first concrete wall component is substantially separated from a second concrete wall component via a rigid plate such that contraction of the first concrete wall component does not create significant stresses in the first or second concrete wall component so as to create cracks in the first or second concrete wall component. Moreover, a compressible material may be disposed between the rigid plate and/or the first and/or second concrete wall component such that expansion of the first concrete wall component compresses the compressible material instead of imposing significant stresses on the first or second concrete wall component so as to be likely to form cracks in the first or second concrete wall component.
