ABSTRACT:
A wide-meshed grid fabric, in particular a geogrid, in which warp thread bundles composed of multiple warp threads and weft thread bundles composed of multiple weft threads intersect and surround meshes or lattice openings. To give the grid fabric, which may also be a scrim, a greater volume, whereby, among other things, improved reinforcement of the soil may be achieved, individual threads of a thread bundle in a mesh are longer than other threads of the same thread bundle, the longer threads running in a wave pattern and forming at least one open loop or bulge per mesh; the open loop or bulge may protrude upward and/or downward from the plane of the grid fabric. A plastic coating may stiffen the grid fabric.
