Abstract: The invention describes a surface covering that comprises modules, made up of elements with irregular undulating edge, imitating natural warping of wood. At least one element with irregular undulating edge of a module is unique and an element with at least one irregular undulating edge can be matched, according to the predefined specification, side to side, with at least one adjacent element with irregular undulating edge. Unique element of each module, featuring at least one irregular undulating edge, will be interchangeable with the unique element with an equivalent irregular undulating edge that forms a part of another module. Modules can be matched mutually, at horizontal plane, to the shape of irregular undulating edge of the outmost element of module, at least in part, according to the predefined specification, given above; the modules can be also matched to each other at ends, according to the predefined specification, thus forming a repeating pattern.
