FIELD: playing ground covering. SUBSTANCE: covering is formed of synthetic "grass mat" having flexible base web composed of plastic threads closely spaced one from another and directed upward so as to imitate grass stems and forming dense sod imitating surface. "Grass mat" is placed onto shock-absorbing substrate formed from thick molded layer of foamed granulated polypropylene having open cells. Elastically compressible polypropylene substrate is joined to sod imitating mat, which makes an impression very close to that produced by natural grass covering of playing grounds. Synthetic sod covering is used for covering golf or tennis playing grounds. EFFECT: simplified structure of covering and wider range of use. 10 cl, 9 dwg
