Abstract: A no-return flow, self-draining, floor mat, comprising a mat with a no-return flow valve drain and a method for making is taught. The drain, emanating from an aperture in the mat, is positioned to pass through the floor for gravity-flow drainage of liquid and debris to the exterior. The no-return flow valve comprises a valve body having a back-flow prevention means and eliminates the need for a cap over the drain. The mat is usable in automobiles, trucks, and other vehicles with, or without, a floor divider mound, mobile and other homes. The mat is resistant to microbes and may additionally contain an anti-microbial substance to further reduce any growth of bacteria, mold, or mildew. The mat may contain a slow-release air freshener and is made of pliable material for a tight fit with a vehicle floor. The floor may be made by a molding technique from rubber or plastic.
