Abstract

A water resistant expansion joint system includes foam, which has been formed into a desired shape by at least one of stamping, cutting, molding and die-cutting; and a layer of an elastomer disposed on the foam. The layer of the elastomer facilitates compression of the water resistant expansion joint system when installed between substrates. The desired shape of the foam includes an angle, and the water resistant expansion joint system is angled around a corner and accommodates thermal and seismic movement in the system by expanding and contracting, and creates a waterproof seal around the corner upon expansion of the foam between the substrates.
