A Composite Filter Sock Assembly includes a Compost Filter Sock and Secondary Tubular Seam Filling Device configured to be wedged beneath the compost filter sock, whereby the compost filter sock provides a pinning pressure to the Secondary Tubular Seam Filling Device and wherein the compost filter sock has a nominal diameter of 2-12 times a diameter of a tubular element of the Secondary Tubular Seam Filling Device. The Tubular Element may be least partially filled with a swell-able material such as sphagnum peat moss and may include a fastening mechanism on an exterior surface configured to facilitate coupling to a mesh tube of a compost filter sock.

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.

The invention pertains to an agro- or geotextile (1), comprising: i) a carrier (2); and ii) an electric network (3) of one or more lighting units (4, 18), whereby said electric network (3) of one or more lighting units (4, 18) is provided on a surface of said carrier (2). The invention further pertains to a method for producing an agro- or geotextile (1) and to a use of an agro- or geotextile (1) according to the current invention.

A shoreline protection and bank stabilization system and method are provided that creates a living shoreline suitable for a variety of soils and wave energy conditions. A combination of recycled plastic matrix layers of geo-synthetic recycled plastic matrix sheets is employed, including matrix sheets that are planted during installation and those that contain pre-grown vegetation. The sheets are secured on a newly constructed or existing levee, earthen berm or earthen terrace. When installed, the system protects and stabilizes banks and shorelines with a variety of soils including loose organics. The system also stabilizes and protects banks and shorelines from a variety of wave energy environments including open water wave action in coastal waters throughout the United States and internationally, but especially in the coastal environment of Louisiana and the Gulf Coast.

A reinforced geocell is made of flexible polymeric strips arranged in rows and interconnected in a staggered order lengthwise to form a three-dimensional cell structure when stretched in the direction normal to surfaces of the strips. The strips are provided with drainage apertures and are reinforced in a longitudinal direction with reinforcing threads having at least two fibrous elements twisted along full lengths thereof. A method for producing a geocell includes extruding a polymeric material for producing a sheet material, laying out twisted reinforcing threads onto the sheet material, calendaring the sheet material when heated to 120 to 200? C. to press reinforcing threads into the sheet material, cutting a reinforced sheet material into sheets, perforating the sheets for producing drainage apertures, cutting the sheets into strips, and interconnecting the strips in a staggered order to form a three-dimensional cell structure.

Method for forming a ground-covering layer (1), comprising the steps of providing a sheet (2); forming a number of substantially parallel folds (3) in the sheet; and urging toward each other and connecting to each other adjacent folds at different locations wherein the connections of each fold to an adjacent fold on the one side are offset relative to the connections to an adjacent fold on the other side. Ground-covering layer (1), comprising a sheet (2) with a number of substantially parallel folds (3), which folds are connected at different locations to adjacent folds, wherein the connections of each fold to an adjacent fold on the one side are offset relative to the connections to an adjacent fold on the other side.

A fire resistant ground erosion control mat assembly. The mat assembly includes an inner layer of fire resistant milled stone mineral wool material with an upper and a lower layer of supportive nets. Each of the upper and lower nets consist of fire resistant milled mineral foraminous nettings to enable passage of light and water therethrough as a ground positioned emplacement of the inner layer.

An in-situ purification island structure and the construction method thereof, which refers to the field of sewage treatment technology. The in-situ purification island structure comprises the upstream purification island main body and the downstream purification island main body, in which the upstream purification island main body comprises the first base backfill layer, the first lower layer, the first hydrophobic layer, the first water permeable layer and the first upper layer. The first ecological bags are set around the surface of the first base backfill layer. The first lower layer has center formed with a lower layer backfill transitional zone. The first hydrophobic layer has center formed with a hydrophobic layer backfill transitional zone. It has a good natural purifying effect on the sewage, saves the investment and cost, no limitation on the applications, the capacity and efficiency of the purifying is high, and saves the resource.

A ground anchor system configured for introducing into a borehole, and comprising a plurality of straps each having a length dimension extending along a central longitudinal axis of the ground anchor system. Each of said straps has a width dimension taken along a major axis and a thickness dimension taken along a minor axis. The major axis and the minor axis are disposed at a transverse plane of the ground anchor system and intersect at a middle point. The middle point of each of said straps is intersected by an imaginary line extending through the longitudinal axis at the transverse plane. The imaginary line forms an angle smaller than 90 with the major axis of the respective strap.

The present invention relates to an erosion control apparatus and methods of using and installing the apparatus. The apparatus is constructed to prevent erosion of soil during typical weather or tidal conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline.
