Made from recycled rubber and PVC, Safety Deck II Grass Surfacing consists of interlocking, nonslip mats that protect grassed areas subject to continuous wear and tear, such as around playground equipment, on pathways, at gateways, and in other high-foot-traffic places. Allowing the grass to grow through it while protecting the soil and roots beneath, Safety Deck II makes a grass surface accessible to wheelchairs, even right after a rain or watering.
