A ventilated interlocking floor tile is disclosed comprising a lower layer including a heavy, substantially solid edge region provided with a plurality of interlocks for attachment with contiguous tiles and an upper layer securely fastened to the lower layer to form an upper floor surface including a unidirectional slip-resistant tread pattern. The solid edge region defines a cavity on the backside of the tile and includes a plurality of ventilating grooves extending from the cavity to the outer edge of the tile to accommodate the flow of air to and from the cavity. The upper layer is secured to the lower layer such that the upper layer overlies the interlocks of two predetermined sides of the solid edge region of the lower layer whereby the exposed interlocks of the remaining sides of the edge region of the lower layer may only interlock with the covered interlocks of a contiguous tile thereby maintaining uniformity in the pattern defined by the unidirectional tread pattern of the upper layers throughout the floor surface covering constructed by the floor tiles.
