<p>A fabric mat protecting against erosion comprising a water-pervious fabric layer-provided with anchoring loops. The anchoring loops have the form of a yarn woven across the fabric and protruding from the surface thereof. It is possible to use for this purpose a rugged yarn guaranteeing a satisfactory anchorage. The anchoring loops of the fabric ensure that the mat penetrates into the ground and is thus anchored. It is also possible to anchor concrete blocks of means of the anchoring loops by pouring the concrete on the mat or by pressing it thereon.</p> |
