The “XL is Unity’s 4” and 4 ½” (2017) thick rubberized safety surfacing, flooring and paver products that are made from 100% recycled (waste) tires and rubber. These double tiles/mats/blocks/pavers have a unique self-interlocking design with “Button-Lock™” Technology (for Ballast) that offers bolt down capabilities (for playground use). The extra large coned bottom (feet and/or legs) allows for free flow drainage to a drainage outlet while at the same time providing cushion from falls onto the surfacing below, passes a twelve (12’) foot fall rating collectively. Our XL-Series are found mostly on TALL playgrounds, daycare centers, recreational areas, pools, climbing walls and in water & amusement parks where very tall drop heights are an issue. They are also used in many other applications that are found indoors and outdoors, acoustical areas for noise reduction and even rooftops where ballast is an issue.
