  • Patent number: 12270174
    Abstract: A bracing assembly for a geosynthetic wrapped system is provided. The bracing assembly includes a standing brace bar, a bottom brace bar, and a cross brace bar having different configurations to facilitate both easy and mistake free assembly of the bracing assembly. Furthermore, the standing brace bar and the bottom brace bar include guide tips that are sized and shaped to direct insertion of the standing brace bar and the bottom brace bar respectively into a weave of a geotextile fabric material such that a first connector of the bottom brace bar and a first connection slot of the standing brace bar are aligned together and with a fold line of the geotextile fabric material.

  • Publication number: 20210008850
    Abstract: A process for the production of a polymeric article directed to (a)forming apply having successive layers, namely, (i) a first layer made up of strands of an oriented polymer material; (ii)a second layer of a polymeric material; (iii)a third layer made up of strands of an oriented polymeric material, wherein the second layer has a lower peak melting temperature that of the first and third layers; (b)subjecting the ply to conditions of time, temperature, and pressure sufficient to melt a proportion of the firsts layer to melt the second layer entirely, and to melt a proportion of the third layer, and to compact the ply; and (c)cooling the compacted ply. The resultant articles have good mechanical properties yet may be made at a lower compaction temperature than articles not employing the second layer, leading to a more controllable manufacturing process.

  • Publication number: 20180371715
    Abstract: A pyramidal geotextile fabric comprising two sets of multi-lobe filament yarns interwoven in substantially perpendicular direction to each other, each of the multi-lobe filament yarns having pre-determined, different heat shrinkage characteristics such that, upon heating, the fabric forms a three-dimensional, cuspated profile. A method of stabilizing soil and reinforcing vegetation comprises the steps of placing a three-dimensional, high-profile woven fabric into soil, wherein the fabric comprises two sets of multi-lobe filament yarns interwoven in substantially perpendicular direction to each other, each of the multi-lobe filament yarns having pre-determined, different heat shrinkage characteristics such that, upon heating, the fabric forms a three-dimensional, cuspated profile; securing the fabric to the ground; and, distributing soil and seed onto the fabric such that the section of ground is quickly revegetated and thereby protected from further erosion.
