Abstract
A composite floor covering having an upper layer of a decorative fabric, a dimensionally stabilizing intermediate layer, and an optional lower cushioning layer has at least the upper surface of the decorative fabric coated with a protective polymeric coating in a manner such that the hand of the decorative fabric layer is substantially retained. The materials of the fabric layer, stabilizing layer, and cushioning layer (if provided) as well as the form of attachment therebetween, cooperate to render the floor covering substantially impervious to liquid.
