Patent number: 8596930Abstract: An erosion control barrier for installation in a drainage path in a service environment. The erosion control barrier includes a unitary permeable sheet which is bent along a longitudinal axis to provide an upslope side, a downslope side and a longitudinally extending apex. The permeable sheet is constructed of a degradable material so that the erosion control barrier has a design service life in the service environment and a design material life in the service environment. The design material life is longer than the design service life. The permeable sheet is designed to be sufficiently transversely stiff and resilient during the design service life to enable the erosion control barrier to be self-supporting. The permeable sheet is designed to substantially disintegrate within the design material life.Type: GrantFiled: May 10, 2007Date of Patent: December 3, 2013Assignee: Nilex Inc.Inventors: Walter van Woudenberg, Ian Wilson

Publication number: 20130294847Abstract: A cellular confinement system for soil, sand or other filler material comprises a number of sub-assemblies each made up of a plurality of interconnected open cells of fabric material. The sub-assemblies are stackable one on top of the other to provide a structure having at least one generally vertical side or end wall. Each sub-assembly comprises a skirt portion which is arranged to overlap between vertically juxtaposed sub-assemblies in use. The skirt portion substantially prevents or minimises the escape of finer aggregate material from between the stacked sub-assemblies.Type: ApplicationFiled: April 16, 2013Publication date: November 7, 2013Inventors: Jeremy Milton, Basil John Thomas

Patent number: 8562259Abstract: A retaining wall system formed from a wire facing unit having an upstanding face section and a rearwardly extending floor section the rear end of which is provided with aligned, transversely extending, openings defined by upstanding U-shaped protuberances. The apertures in the forward portion of a geogrid can be seated over the protuberances and a connector strut interconnects the face section and floor section for providing support therebetween and for securing the geogrid to the floor section. The connector strut includes an elongated rigid rod having a curved first end that extends to a substantially right-angled bend, and a connector rod portion extends from the bend to a second end to secure the geogrid to the floor section.Type: GrantFiled: October 14, 2010Date of Patent: October 22, 2013Assignee: Tensar International CorporationInventors: Jon Robert Ridgway, Willie Liew, Robert Lloyd Talbot, Jeremy Lee Stafford

Patent number: 8544220Abstract: A procedure for making swimming pools and artificial lakes in general includes the following steps: excavation of a tank; preparation of a subgrade by spreading the bottom of the excavation with a layer of sand; then spreading one or more sheets of nonwoven fabric on the inside surface of the excavation, over the layer of the subgrade; placement of a waterproofing layer over the sheet(s) of nonwoven fabric; installation of the equipment needed for proper functioning of the tank, swimming pool, etc; and application of a coating on the inside walls and/or on the bottom and/or around the edge of the tank, with holes or interstitial spaces such to enable water contained inside the tank to come into contact with the sheets, wherein the thrust of the water contained in the tank thus comes to bear on the sheets.Type: GrantFiled: July 7, 2009Date of Patent: October 1, 2013Inventor: Alessandro Milani

Publication number: 20130251461Abstract: A method for producing a safety net, to a safety net, and to the use of such a safety net for protection from avalanches, falling rock or timber, mudslides, earth flows, or for slope protection. In the inventive method, firstly at least a first net element and at least a second net element are individually produced, self-contained, from respectively at least one rope, and are arranged parallel to each other and at a distance apart in a longitudinal direction of the safety net to be formed. Then the two net elements are connected to each other with the aid of at least one connecting rope, wherein the connecting rope is guided between the first and the second net element such that a self-contained connecting net element is obtained.Type: ApplicationFiled: March 4, 2013Publication date: September 26, 2013Applicant: ISOFER AGInventor: Marcel FULDE
