Abstract: A tile structure and a tile assembly comprising a plurality of substantially equivalent, interconnected tile structures disposable in covering relation to a floor or other surface area. Each tile structure comprises outer and under layers fixedly secured in longitudinally and transversely offset relation to define a connecting groove and a connecting tongue extending along opposite longitudinal and transverse peripheral portions thereof. The connecting tongue on each of the plurality of tile structures is cooperatively dimensioned and configured to fit within the connecting groove on a next adjacently disposed tile structure. Secure interconnection between the tile structures is facilitated by a pressure sensitive or dry adhesive composition disposed on one surface at least partially within the connecting groove, while the remaining surfaces of the connecting tongue and groove are initially adhesive-free.
