An expansion joint and seal is provided that is adapted for adherence to a wall and floor interface. The joint is operative to seal the interface such that self-leveling materials cannot flow between the wall and the floor. When adhered to the interface, a compressive member may be disposed coincidental to the wall. This compressive member allows for expansion of solidified self-leveling materials relative to the wall. In one arrangement, the joint and seal utilizes a flexible sheet member having a bottom surface that is adapted for adherence to the interface of a wall and floor. A compressible member is attached to the top surface of the flexible sheet member. The bottom surface of the flexible sheet member may also include a peel-away release member that covers an adhesive disposed on the bottom surface.
