  • Patent number: 8777523
    Abstract: A flexible water-permeable geotextile tube having flat ends when filled with fill material. The tube has separate end panels that are attached to a tube body at the tube body's opposing ends. In one embodiment of this invention, the separate end panels are configured to have the same shape as that of a cross-section of the tube body when the tube body is filled and installed. The cross section of the tube body may be determined before installation by determining the relationship between the height, circumference, the fill material, and the surrounding environment into which the tube is planned to be installed.
    Type: Grant

  • Patent number: 7112283
    Abstract: A method and system of processing animal waste, whereby liquid is removed from the waste and recycled for use in other applications. Moreover, use of the method and system facilitates capture of the solid waste, which may then be used as fertilizer. In the present method and system, waste sludge is fed into a geotextile container, which functions as a filter. The liquid from the sludge permeates the geotextile container, while the geotextile container retains the solid waste. Multiple geotextile containers may be used to further filter and clean the liquid. The liquid exiting the geotextile container flows into a liquid reservoir, from which the liquid may be drawn for use in other applications. During this process, the solid waste is trapped in the geotextile container, where it will digest and compost and may be easily accessed for use as fertilizer or other nutrients.

  • Patent number: 5651641
    Abstract: Tufted mats for a broad variety of erosion control, turf reinforcement, and earth reinforcement applications. The mats are formed of scrim which is tufted, preferably on conventional carpet machinery, with a number of tufted ends in order to provide high tensile strength, greatly porous and flexible mats which may be easily installed, but which contain a number of interstices for capturing root systems, retaining soil, and controlling the flow of water. The properties of the mats may be easily controlled and optimized by controlling the properties and arrangements of the cross machine ends and machine ends forming the scrim if woven (or corresponding ends, filaments or fibers if knitted or nonwoven), as well as the tufted ends which are tufted into the scrim.
