the internal flanges 15 are provided parallel to the side edges 11 and asymmetrically located so that the tile can be cut between domes without cutting the domes and a perimeter flange is provided at the cut so that shorter lengths can be utilized as required the flanges 14 and 15 have holes 16 through them to assist in anchoring the tile in the surface of the platform commonly freshly poured concrete by anchoring the tiles with the concrete through the holes the need for adhesives or mechanical fasteners which are labour intensive to install are eliminated or reduced in addition by eliminating mechanical fasteners there are no holes in the top surface of the tile into which water can seep causing problems with degradation and freezing the holes in the perimeter flanges 14 permit any trapped air to vent out the cells under the tiles parallel to the direction of travel when they are pressed into the concrete in the preferred embodiment the flanges 14 and 15 depend about 11 4 34 from the bottom surface 20 and holes 16 have a diameter of about 3 4 the top surface 10 of the tile 1 has a plurality of rows of spaced truncated domes 17 projecting upwardly therefrom providing a distinctively textured surface relative to the texture of the surface of the platform the truncated domes preferably are circular and comply with the ada accessibility guidelines or are subject to an order for equivalent facilitation under.
