Play-Land is Unity’s 2 1/2" thick rubberized safety surfacing, flooring and paver product made from 100% recycled tires and rubber that is clean and safe to use. These double tiles/mats/blocks/pavers have a unique self-interlocking design with "Button-Lock™" Technology (for rooftop use) that offers bolt down capabilities (for playground use)..... that can ONLY be found here. The medium size coned bottom (feet and/or legs) allows for free flow drainage to a drainage outlet while providing cushion from falls onto the surface below. This product passes a up to a seven (7’) foot "drop height rating", and are found mostly on rooftops, playground, daycare centers, recreational areas, pools & patios, walkways, marina & docks and in water & amusement parks. They are also used in many other applications that are found indoors and outdoors, and even acoustical areas for noise reduction. 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. There are no retaining edges needed and all of Unity’s rubberized safety surfacing, flooring and paver products are accessible to the handicapped. They are water permeable, easy to install and fully warranted.
