Made in North America from 100% recycled rubber, Envirotile has saved approximately 3 million tires from being sent to the landfill. Due to the nature of recycled materials, the tire rubber will vary from tile to tile. This variance results in each tile’s naturally unique color as well as size, equaling up to ¼ in. size difference from tile to tile. Envirotile is a “floating floor” system with a patented clipping system (sold separately) that provides the ease of a do-it-yourself application. These tiles can be installed on top of any existing hard surface such as wood, concrete, and patio tiles. The “floating floor” system is an investment; it is simple to pick up your tiles and move them to another location.
