gummiduk

Gummiduk is a term used in Scandinavian languages, notably Danish, Norwegian, and Swedish, to refer to a sheet or large piece of rubber intended as a waterproof covering or protective layer. The word combines gummi, meaning rubber, with duk (or dukken), meaning cloth or sheet. The material can be natural rubber or a synthetic elastomer and is often vulcanized for durability. Thickness varies by intended use.

Typical uses of gummiduk include protective covers for tables, floors, or equipment, waterproof liners and membranes for construction, ponds, or agricultural applications, and lining or damp-proofing in various settings. It may also serve as packaging or crate lining and as industrial mats. In domestic settings, a gummiduk might be employed as a heavy-duty waterproof cover for outdoor gear or as a flexible floor mat in damp areas.

In English-language contexts, the term gummiduk is uncommon; materials of this type are usually described as rubber sheets or rubber mats rather than by the Nordic term. When encountered in Nordic sources, the concept is understood as generic rubber sheeting suitable for a range of waterproof or protective applications.
