Tough-Land is "Unity's" ½", ¾" and 1 3/8" (inch) thick solid tile/mat/block/paver. It comes in our exclusive 2X2 formation with a very small coned (feet and/or leg) bottom design made from 100% recycled (waste) tires and rubber in order to maximize comfort. They are ideal for indoor and outdoor applications such as: weight rooms, golf facilities, walkways, athletic & work areas, ice rinks, ski lobbies, laundry rooms, entrance and exit ways, basements, walls and many other high traffic areas. They are easy to clean and safe to use, resulting in low maintenance costs. They do not displace during usage and create consistent shock absorbency year round. The low life costs makes for very good footing thus preventing leg fatigue. Tough-Land is a noise-reducing, puncture resistant product that can withstand heavy blows and high traffic making it a perfect solution for upper level locations or where sound reduction is a requirement. It is easy to install and is fully warranted. Please note: the ½" and the ¾" thick do not interlock, only the 1 3/8" thick interlocks.
