ABSTRACT:
An elastomeric sealing apparatus for waterproofing a joint opening between two generally parallel structural members in highways, bridges, parking structures and the like. The sealing apparatus comprises an elongated web shaped elastomeric body member which assumes a bowed contour after installation and which spans a joint opening defined by the faces of two confronting structural members such as roadway slabs or the like. The body member has side flaps extending integrally along each longitudinal edge thereof. The side flaps are adapted by steps and outward bias for adhesive bonding to the joint faces so as to provide watertightness, easy installation, and long term resistance to climatic conditions and structural movements.
