The molded rubber tile has a turf surface that looks like real grass. Tiles measure 24 x 24 in. and are 2 1/2-in. thick. The material can be used inside or outdoors on surfaces including patios, rooftops, or playgrounds. Installation with Quad Blok interlocking connectors attaches to the understructure of the tiles.
