Patent ID: 6858272

Claim:
An artificial turf system comprising: a base that is readily constructed, at least in part, from naturally occurring ground elements that are present upon initiation of the construction of the base, the base being constructed to include a drainage mechanism that is disposed near the surface of the base; and a turf assembly that is laid out upon the base and that is constructed to pass fluid therethrough such that the fluid is specifically directed to the drainage mechanism of the base as it moves through the turf assembly, the turf assembly comprising a plurality of layers including: an impermeable moisture barrier layer that is laid upon the base such that the fluid may only pass to the base at predetermined locations that correspond to the drainage mechanism; a drainage layer disposed upon the impermeable moisture barrier layer that creates an area where fluid is free to pass to the impermeable moisture barrier layer and ultimately to the drainage mechanism of the base; a filtering layer disposed upon the drainage layer that filters out undesirable particles from the fluid as the fluid passes through the filtering layer and into the drainage layer, the area between the filtering layer and the impermeable moisture barrier layer being permanently available whether or not fluid is passing therethrough; and a turf mat disposed upon the filtering layer having grass on an upper surface to give the artificial turf system the appearance of a completely natural grass field.
