Patent number: 11933013Abstract: An integral geogrid includes a plurality of interconnected, oriented strands having an array of openings therein that is produced from a coextruded multilayer polymer sheet starting material. By virtue of the construction, the coextruded multilayer sheet components provide a crystalline synergistic effect during extrusion and orientation of the integral geogrid, resulting in enhanced material properties that provide performance benefits to use of the integral geogrid in soil geosyuthetic reinforcement.Type: GrantFiled: November 10, 2021Date of Patent: March 19, 2024Assignee: TENSAR CORPORATION, LLCInventors: William Stanley Shelton, Manoj Kumar Tyagi

Patent number: 11873717Abstract: A polymer mesh for skin control in hard rock mining conditions is provided. The polymer mesh is manufactured using a knitted or woven design that further includes one or more pairs of solid cut-resistant bands. The bands are positioned in pairs, each band in a pair having a width of at least about 2.5? and being generally parallel with the other band. The bands are spaced from one another at a distance of between about 1.5? and about 4? to create a reinforced aperture between the bands. One or more reinforcement bolts are installed within the aperture with the bands on opposing sides of each bolt buffering the edges of the steel plates associated with the bolts to prevent the plates from tearing the polymer mesh.Type: GrantFiled: April 12, 2022Date of Patent: January 16, 2024Assignee: TENSAR CORPORATION, LLCInventor: John Steffenino

Patent number: 8651770Abstract: An erosion control ballast and soil confinement mat for use in water flow conditions is provided. The mat is made of a non-buoyant, relatively heavy and substantially flexible material with a plurality of pores stamped or pre-cast therein that allow for the inflow of water, the establishment of vegetation growth through the mat, and the in-filling of the pores with supplemental ballast materials such as gravel or soil. The bottom side of the mat has protrusions that extend into the underlying surface to prevent horizontal shifting and confine soil materials and/or another erosion control mat such as an erosion control blanket or turf reinforcement mat, while also preventing migration of the mat itself under high shear force water flow. The top surface of the mat may be provided with flaps that cover the pore openings during periods of strong water flow to prevent excessive water flow from entering the pores and eroding the underlying soil.Type: GrantFiled: August 18, 2009Date of Patent: February 18, 2014Assignee: Tensar Corporation, LLCInventor: Timothy Lancaster

Patent number: RE49523Abstract: An integral polymer grid with a plurality of interconnected, oriented polyethylene terephthalate strands and an array of openings therein is made from a polyethylene terephthalate sheet-like starting material having holes or depressions therein that form the openings when the sheet-like material is uniaxially or biaxially stretched. The grid has a higher tensile strength to weight ratio and a higher creep reduced strength to weight ratio than corresponding ratios associated with a grid made from a non-polyethylene terephthalate starting material.Type: GrantFiled: January 26, 2018Date of Patent: May 9, 2023Assignee: TENSAR CORPORATION, LLCInventors: Manoj Kumar Tyagi, William Stanley Shelton
