<p>In order to provide uniaxially-stretched and biaxially-stretched mesh structures which allow for different specific designs of the interconnecting strands, a special punching pattern is used to provide holes in the starting material. The starting material has a "square" pattern of large holes. Further holes are added. These further holes can be small holes which are staggered and in pairs. When the starting material is stretched, the uniaxially-stretched structure has transverse bars interconnected by highly orientated strands each of which forks at both ends into further highly orientated strands, providing a structure which is particularly suitable for soil reinforcement. When the structure is stretched in the direction at right angles to form a biaxially-stretched structure, the zones of the bars which are between aligned strands remain as unorientated or partly orientated junctions. The remaining zones of the bars are stretched out to form highly orientated strands. This biaxially-stretched structure is particularly suitable for soil stabilization.</p> |
