Abstract
A synthetic-grass structure for laying on a subfloor comprises a sheet substrate with a plurality of filiform formations extending upwards from the substrate to simulate natural grass cover and a particulate filling material or infill dispersed between the filiform formations in such a way as to maintain the filiform formations in a substantially upright condition. The infill includes a substantially homogeneous mass of a granular material selected from polyolefin-based materials and vinyl-polymer-based materials, preferably recycled ones.
