Abstract
A synthetic turf system is disclosed. The synthetic turf system comprises a synthetic turf system and a poured-in-place (PIP) rubber subsurface. The PIP rubber subsurface is poured with a mixture of rubber buffing and urethane configured to deliver improved safety, playability, and reduced maintenance requirements for the synthetic turf placed on a playing surface. The PIP rubber subsurface is made with rubber buffings combined with a binder such as polyurethane. The system further comprises a layer of compacted gravel disposed underneath the PIP rubber subsurface configured to allow drainage. The system further comprises a plurality of cooling particle infill to avoid dislodging of infill into athlete's shoes, clothes, eyes, or ears. Further, the infill is substantially free of crumb rubber infill and the system is without the use of added shock pads. Further, the system is configured to maintain a consistent concussion resistance throughout the entire playing surface.
