Whether you are resurfacing an existing playground, or installing a new one, Unit's products are the smart choice for your safety surfacing investment. Our products are made of up to 95% post and pre-consumer recycled materials, and are easy to install thanks to our self-interlocking connection with button-lock technology.....it's that easy. Unlike traditional 2X2 tiles, Unity's products do not separate, curl, nor peal due to the sheer size of our products (22"x44") and the "step & repeat method, coupled with our bolt-down capabilities, which means your playground surfacing project will last. Our 3.5" thick Soft-Land Series was selected by the local community, architect, engineer and town using 45% Green, 45% Blue and 10% Black. This playground was redesigned to be counter-sunk to allow the entire entry point to be ADA compliant......something we highly recommended.
