A b s t r a c t The invention relates to a ground covering for open spaces, with which a water-permeable filter mat impervious to granular material is bonded to the underside of a water- permeable artificial grass so that a filling of granular material in the pile of the grass will not be swept away to the edges of the surface covered by the ground covering even in heavy rain since the water may drain immediately through the artificial grass and the filter mat to the underside of the ground covering (drawing).
