Abstract
In order to produce a jointless and porous granular covering (1), rubber-elastic granules (3) and a binder (5) are mixed and applied to a base (7) to form a sheetlike surfacing (6). Prior to the curing of the binder (5), the sheetlike surfacing (6) is compacted and smoothed on its upper side (11). Prior to the curing of the binder (5), the compacted surfacing (15) is provided with a texture (20) on its upper side (14) by being subjected to mechanical pressure using an uneven embossing face (19). The granules (3) preferably have a mean particle size in the range from 0.1 to 3 mm, preferably 0.5 to 1.5 mm.
