<p>An improved surface includes a synthetic turf base (104) positioned atop a foundation (102). The synthetic turf base (104) includes imitation grass blades (110) secured to a backing (112). The synthetic turf base (104) also includes a surface layer of material (118) supported by the backing (112) and intermixed with the imitation grass blades (110). Natural grass (120) is planted in the surface layer of material wherein the natural grass (120) includes natural grass blades (122) and roots (124). The backing (112) is provided with perforations or openings sufficient in number to permit the roots (124) of the natural grass to extend through the backing into the sub-base (108) of the foundation (102). The natural grass (128) 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.</p> |
