<p>For use as an underwater covering mat to minimise erosion, there is provided a dimensionally stable, flexible and open-mesh woven fabric composed of thread like wire elements as warp and weft. The construction is characterized in that the warp elements are arranged in groups and the distance between each two successive groups, as well as between each two successive wefts, is between 0.8 cm and 6 cm. The clamping force of the warp elements on the weft elements in a group is such that axial shift of the weft elements occurs only in the event of axial tensile loading of at least 1% of the breaking strength of these weft elements.</p> |
