<p>A synthetic grass surface for a sports playing field comprises a flexible backing member 3, parallel rows of synthetic ribbons 7, representing blades of grass, projecting upwardly from the backing member, the rows of ribbons spaced apart from each other, and a relatively thick layer 9 of particulate material on the backing member supporting the ribbons in a relatively upright position relative to the backing member, whereby the length of the ribbons is at least twice the spacing between the rows and the particulate material layer 9 has a thickness of substantially 2/3 the length of the ribbons.</p> |
