This is the system that is used in tartan tracks most commonly and also known as the sandwich system. A mix of special granulometric recycles rubber and elastic polyurethane is spread on the floor at the desired thickness with the help of a paving machine on the application field. Supporting it with 2K elastic polyurethane sealer and selfleveling systems and spreading granulometric EPDM at desired thickness and colors, the lane lines are applied and the process is finished. The system meets the IAAF requirements and contains Elastic Polyurethane components. It provides floors that have high performance and long life and no requirement for maintenance.
