Abstract
A synthetic grass assembly for installation on a supporting soil substrate includes a pile fabric with a flexible sheet backing and rows of upstanding synthetic ribbons representing grass blades, extending upwardly from an upper surface of the backing. An infill layer of two distinct graded courses of particulate material is disposed interstitially between the upstanding ribbons upon the upper surface of the backing and of a depth less than the length of the ribbons. A bottom course of intermixed hard sand and resilient rubber granules with substantially identical particle size distribution characteristics is installed upon the backing and a top course exclusively of resilient rubber granules is placed upon the bottom course.

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, wherein the infill layer comprises:
- a bottom course of intermixed hard and resilient granules of substantially identical size distribution, disposed upon the top 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.
