The garage floor tiles we manufacture are made out of high-impact polypropylene (high-impact plastic). There are other manufacturers t hat make them out of flexible pvc (aka rubber). We use polypropylene in order to make the garage tiles with a grid underneath for air and water flow. This prevents mold growth. The added benefit to polypropylene is that it makes the tiles very easy to clean and for the most part stain resistant.
