A water-impermeable infilled solid plastic covering (type E) with a granular surface used for high-performance sports. PUR is applied in several layers, with granules infilled into this coating. The solid plastic covering reconciles two contradictory requirements which athletes expect modern running tracks to fulfil - the covering should be as hard as possible for sprinters, yet soft and low-impact for long-distance runners, while also returning energy to the athlete. Different polyurethane coatings tailored to these needs are combined with Melos granules to create a high-tech covering system which meets the extensive needs of modern track athletes and delivers convincing results.
