Abstract (en)
[origin: WO9956523A1] An improved playing surface (100) including a synthetic turf base (104) positioned atop a foundation (102) is provided. The synthetic turf base includes synthetic fibers (110) secured to a knitted backing (800). The synthetic turf base also includes a surface layer of growth medium (118) applied on top of the knitted backing to reach a predetermined depth. Natural grass (120) is planted in the surface layer of growth medium. The knitted backing includes openings (116) sufficient in number and size to allow roots (124) of the natural grass and water to pass through so that the natural grass will grow to form a playing surface.
