Abstract
An artificial turf assembly has a permeable section formed of an upper layer of artificial turf and a lower layer of shock absorbing material positioned below the upper layer. An impermeable layer is positioned below the permeable section for collecting water flowing downward through the permeable section. The permeable section is separable from the impermeable layer to form a space for the water flow away from the assembly. The space may be formed by having the permeable section lying on the impermeable layer so that it lifts off the impermeable layer and floats on the water that flows through the permeable section. Alternatively, rigid spacing members may be provided for maintaining space between the permeable and impermeable layers in the absence of water.
