Abstract

A vertically draining, particulate confinement structure may prevent side to side migration of particulate materials and may provide a way to ensure a consistent fill depth of the particulate materials. The particulate materials may include rubber granules. The vertical draining feature of the system may prevent water from accumulating on the turf surface by providing adequate vertical drainage. The vertical draining feature may be attributed to the combination of the turf surface with a confinement structure and the particulate materials that support this turf surface. The confinement structure and particulate materials also inhibit underlayment migration of the turf surface.
