<p>The new slab (1) consists of a granulated material made from old tyres, which is intimately mixed with a two-component binder and is thus made into a moulded material by moulding. The slab (1) possesses edge knobs (10) and edge knobs (13, 14), which are arranged on its underside mutually offset at regular distances. In this case, the edge knobs (13, 14) always form only parts of a whole knob (10) and only become whole knobs (10) when two or more slabs (1) are joined together. A plurality of slabs (1) can be held together to form a floor covering by means of a ring (19) which can be slipped over the edge knobs (13, 14). <IMAGE></p> |
