Abstract: The invention relates to a grid of synthetic material with two groups of parallel, load-bearing strands, wherein the strands of the first group extend in the longitudinal direction of the grid and the strands of the second group extend transversely to the longitudinal direction of the grid and the strands of both groups are joined together at their points of intersection. Alternating first and second portions are formed with strands extending in the direction of one of the two groups. The strand spacing of the first portions are larger than the strand spacing of the second portions. The second portions can be of an increased strength and can be used to fasten the grid without aids.

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.

Abstract: Grid mat with warp thread strands running at regular intervals lengthwise or in the warp direction and weft thread strands running at regular intervals crosswise or in the weft direction connected to the warp thread strands at the points of intersection with the warp thread strands by raschel knitting, stitching, interweaving, adhesion or welding. The edge areas of grid mats placed next to each other are laid on top of one another and connected by threading elements such as rods or cord. The threading elements are inserted through the links of the mesh in the edge area.

Abstract: The invention relatrs to a wide-meshed fabric (1) treated with bonding agents. The inventive mesh is made up of bundles (4) consisting of several warop threads (3) and bundloes (6) consisting of several weft threads (5) surrounding the inner meshes (7). The warp threads (3) are interwoven with the weft threads (5) at intersection points (5) of the bundles (4) of warp threads and bundles (6) of weft threads (5) running at right-angles to each other. In order to firmly secure the warp threads and the weft threads, the bundles (4) of warp threads are divided into a first group (4′) of warp threads and a second group (4″) of warp threads and the first group of warp threads crosses over the second group of warp threads threads belonging to the same bundle (4) of warp threads for each mesh (7) thereby forming a half-twist. Similarly, the warp threads (3) of both groups (4′, 4″) of warp threads are interwoven with the weft threads (5), running substantially parallel to each other.

Abstract: The invention relates to a wide-meshed, textile lattice to provide reinforcement for bitumen-bonded layers, in particular of road surfacing, which is coated with a bonding compound having an affinity for bitumen and essentially consisting of two sets of parallel, load-bearing threads (1, 2), whereby one set of threads (1) extends in the longitudinal direction of the lattice and the other set of threads extends in the direction perpendicular to the longitudinal direction of the lattice and the threads (1, 2) are of glass fibres or chemical fibres such as polymer fibres or polycondensate fibres. In order to develop a reinforcing lattice for bitumen-bonded layers which provides a better bond with a pre-prepared formation than the known lattices, the over-crossed threads (1, 2) are secured to a thin fleece (3) by Raschel-locking, whereby the binding Raschel-locking threads (5) surround the longitudinally extending threads (1) of the lattice and secure the threads (2) extending transversely.

Abstract: The invention relates to, in particular, a geotextile comprising linear running warp threads (1) and linear running weft threads (2) which are essentially orthogonal thereto. Said weft threads are joined to the warp threads (1) by means of fixing threads (3) which are applied by warp knitting and whose meshes wrap around the warp threads (1) along the entire length and around the weft threads (2) in the area of crossings (4). The warp threads (1) and the weft threads (2) are arranged individually or in groups in larger intervals which result in inner widths (5) of the mesh (6). The aim of the invention is to attain an improved joining of warp threads and weft threads without requiring the use of additional fixing threads or stronger fixing threads.

Abstract: Composite fabric for reinforcing soil layers, including a textile lattice and a water-permeable, flat textile structure which is joined to the lattice. The invention provides a geotextile composite fabric web whose positioning not only achieves good reinforcement but also allows for the rapid and reliable consolidation of the subsoil situated beneath the textile composite fabric web. The lattice includes strips which are at least 4 cm wide, extend at distances of at least 30 cm in the longitudinal direction of the composite fabric web and have high tensile strength, and second strips which are at least 4 cm wide, extend at distances of at least 30 cm at right angles to the first strips and have high tensile strength. At the points of intersection, the second strips are joined to the first strips in a non-slip manner.

Abstract: The invention relates to a textile composite material used to stabilize, consolidate or reinforce soils and layers of earth, and which can also be used as a load-carrying drainage or filtering layer and comprises at least one nonwoven fabric (1). The disadvantage of nonwovens, used alone or in textile composites made of various plastic nonwovens, lies in their limited load-carrying capacity. To create a low cost textile composite material comprising at least one nonwoven fabric, having a high tear resistance in a main load direction and the ability to absorb high tensile forces without undue stretching, exclusively parallel, straight, load-carrying plastic filament yarns (2) are knitted, sewed or Raschel-knitted onto the nonwoven (1).
