A liquid-proof seamed article including an elastic laminated panel and a corrugated elastic laminated panel joined at the sealing regions of the laminated panels is provided. In exemplary embodiments, both of the laminated panels are corrugated. The laminated panels each include a textile layer and a protective layer. At least one of the textile layer and protective layer is elastic. An adhesive pre-treatment may be applied to the elastic laminate panel and/or the corrugated laminate panel along respective sealing regions prior to forming a seam. Additionally, the laminate can be stretched to substantially flatten the corrugations prior to forming a seam. By substantially flattening the surface of the corrugated laminated panel(s), an adhesive may be applied such that there are no gaps in the adhesive. The corrugated laminates may be used as material for making garments. An apparatus and a method for making a liquid-proof seamed article are also provided.
