Sports playing surfaces with biodegradable backings

摘要

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.
