Envirotile is made with 100% recycled rubber, produced from car and truck tires; over 1 million tires are diverted from the landfill each year. An environmentally-friendly product that is the ideal re-surfacing solution to renew, restore and resurface many outdoor and indoor flooring spaces. Resurface old, worn, cracked floors in a snap. Designed to look like concrete pavers but has the ease of a do-it-yourself application, no contractor required. Lightweight and portable, you can place envirotile directly on top of any existing flat surface; i.e. wood, concrete, patio tiles. Envirotile will not warp, crack, peel, chip or crumble. If you want to secure the tiles together, connector clips are sold separately. Size and weight are approximate.
