Abstract: The invention relates to a composite mat (1) comprising a rough structured surface on the upper side and a smooth closed-planar, watertight surface on the underside. Said composite mat consists of two layers, which are joined to one another, in particular, by welding, adhering or a similar technique, namely of an upper layer made of a woven material (3) and of an underlayer made of an elastic synthetic material (2).
