Tile for an entrance mat

A tile having a flat imperforate base with a top surface and a shape defined by straight sides, said tile comprising low straight walls protruding from said top surface along each side of the base, said wall forming the entire perimeter of the base to hold water on the base, means for use in removably connecting the tile to adjacent identical tiles to form a mat with the outside surface of a straight wall of the tile abutting the outside surfaces of the straight walls of adjacent tiles, scraper members upstanding from and uniformly distributed over said top surface within the confines of said wall, the scraper members comprising a series of spaced-apart ribs extending across the base, the ends of each rib being spaced a short distance from the nearest wall, trough areas between and around said scraper members and between said scraper members and said walls to allow water to flow between said scraper members and reach said walls, and water-directing means formed through each straight wall, said water directing means being located between the corners defined by the junctions of successively adjacent straight walls, said water-directing means positioned for alignment with the water-directing means of adjacent connected tiles for directing water out of the tile to adjacent tiles when the water reaches a certain level on the top surface of the base.
