Abstract
The subject invention is directed to non-metallic flooring elements having a hooked-tongue and groove locking arrangement. Advantageously, the subject invention allows for horizontal interlocking, with no angled introduction needed. As a result, the same locking arrangement can be used for the sides and the ends of the flooring element. This allows for the use of two tools for manufacturing about the perimeter of the flooring element—one tool for the hooked-tongue element and one tool for the groove.
