Straight from the Horse's Mouth

Artificial turf systems for horse-racing facilities are on the rise. For example, the Cushion Track system uses a mixture of sand, silica, and synthetic fibers (elastic, polyester, granulated rubber and polypropylene). It’s installed at, among many, Hollywood Park in Inglewood, California. As the track is on break ahead of its November meet, track operators are guaranteeing continued performance of the racing surface and the separation geotextile by power-washing the geotextile. Officials want to be certain to prevent any clogging of the permeable layer.
