Abstract:
A synthetic grass assembly for installation on a supporting substrate, the assembly comprising:a pile fabric with a flexible sheet backing and a plurality of upstanding synthetic ribbons of a selected length, the ribbons extending upwardly from an upper surface of the backing; an infill layer of particulate material disposed interstitially between the upstanding ribbons upon the upper surface of the backing and of a depth less than the length of the ribbons, the particulate material selected from the group consisting of hard and resilient granules; said infill layer further including a bottom course of intermixed hard and resilient granules, disposed upon the upper surface of the backing, and a top course substantially exclusively of resilient granules disposed upon the bottom course, an upper portion of the synthetic ribbons extending upwardly from a top surface of the top course wherein the synthetic ribbons: are longitudinally intermittently slit in a predetermined pattern of slits; an upper portion of the ribbons extending above the infill layer and longitudinally split into individual free-standing strands of a selected width to represent grass blades; and a lower portion of the ribbons having said slits extended open forming laterally linked strands disposed in a lattice structure enmeshing the surrounding particulate infill material.
