Abstract: A biodegradable playing surface (100) including a synthetic turf base (104) positioned atop a foundation (102) is provided. The synthetic turf base includes an at least partially biodegradable backing (112) having a plurality of openings (116), and synthetic fibers (110) secured to the biodegradable backing. The synthetic turf base also includes a surface layer of growth medium (118) applied on top of the biodegradable backing to reach a predetermined depth. Natural grass (120) is planted in the surface layer of growth medium. The biodegradable backing degrades over time so as to increase the size and number of the openings through the backing. This allows the roots of the natural grass to increasingly grow amongst the synthetic fibers and through the backing, so as to firmly integrate the synthetic turf base to the foundation.

Abstract: An improved playing surface including a synthetic turf base positioned atop a foundation. The synthetic turf base includes synthetic fibers secured to a backing material. The synthetic turf base also includes a surface layer of growth medium applied on top of the backing material to reach a predetermined depth. Natural grass is planted in the surface layer of growth medium. The backing is provided with perforations or openings sufficient in number to permit the roots of the natural grass to extend through the backing into the sub-base of the foundation.

Abstract: An improved playing surface including a synthetic turf base positioned atop a foundation. The synthetic turf base includes synthetic grass fibers secured to a backing material. The synthetic turf base also includes a surface layer of growth medium intermixed with the synthetic grass fibers. Natural grass is planted in the surface layer of growth medium wherein the natural grass includes natural grass blades and roots. The backing is provided with perforations or openings sufficient in number to permit the roots of the natural grass to extend through the backing into the sub-base of the foundation. The improved playing surface may include synthetic grass fibers of varying lengths, longer synthetic grass fibers can be formed of contrasting colors in order to provide line and boundary indicators. A mesh-type material is placed underneath the adjoining layers of backing material in order to reinforce the interface between separate sections of backing material.

Abstract: An improved surface includes a synthetic turf base positioned atop a foundation. The synthetic turf base includes imitation grass blades secured to a backing. The synthetic turf base also includes a surface layer of material supported by the backing and intermixed with the imitation grass blades. Natural grass is planted in the surface layer of material wherein the natural grass includes natural grass blades and roots. The backing is provided with perforations or openings sufficient in number to permit the roots of the natural grass to extend through the backing into the sub-base of the foundation. The natural grass improves the overall desirability of the surface by improving its durability, increasing its life span, reducing the cost of installation, reducing the cost of maintenance, improving comfort for users, and improving the benefits to the ecology.

Abstract: An improved surface includes a foundation constructed of a subgrade and a sub-base. A synthetic turf is positioned atop the foundation and includes synthetic grass blades secured to a backing. The synthetic turf also includes a surface layer of material supported by the backing and intermixed with the synthetic grass blades. Natural grass is planted in the surface layer of material wherein the natural grass includes natural grass blades and roots. The backing is provided with perforations sufficient in number to permit the roots of the natural grass to extend through the backing into the sub-base of the foundation. The natural grass improves the overall desirability of the surface by improving its durability, increasing its life span, reducing the cost of installation, reducing the cost of maintenance, and improving the benefits to the ecology.
