    Abstract: The present disclosure provides a geosynthetic. In one embodiment, the geosynthetic contains a composition containing (A) a polypropylene and (B) from greater than 0 wt % to less than 3 wt % of a halogen-free flame retardant, based on the total weight of the composition. In another embodiment, the geosynthetic contains a composition containing (A) a polypropylene and (B) greater than 20 wt % zinc sulfide, based on the total weight of the composition. In another embodiment, the geosynthetic contains a composition containing (A) a polypropylene; (B) a halogen-free flame retardant; and (C) greater than 20 wt % zinc sulfide, based on the total weight of the composition. The composition has a specific gravity greater than 1.00 g/cc.

    Abstract: An internally braced synthetic mattress is a geosynthetic structure made of a geosynthetic material. The structure has a bottom side, a top side and at least one upright side joining at least a portion of the bottom side and top side. The at least one upright side is formed by an upright fold of the geosynthetic material. A horizontal bar is woven through a portion of the bottom side of the geosynthetic structure and joined with an upright bar and a diagonal bar to form at least one angle brace to support at least a portion of the geosynthetic structure. The geosynthetic structure contains a filler to prevent/reduce erosion.

    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.
