Publication number: 20240125074Abstract: Aspects of a geogrid system and method for improving substrate interactions within a geotechnical environment is disclosed. In one aspect a geotechnical environment is configured with a horizontal multilayer mechanically stabilizing geogrid. In said aspect the geogrid is extruded with a polymeric material and a compressible cellular layer, wherein the geogrid comprises a heightened aspect ratio with a patterned structure of engineered discontinuities and a plurality of strong axes. The combination of elements provides for a system and method of stabilizing soils and aggregate, by resisting lateral movement from the strong axes, and trapping particles in the patterned structure of engineered discontinuities.Type: ApplicationFiled: December 27, 2023Publication date: April 18, 2024Applicant: Tensar International CorporationInventors: Andrew CURSON, Tom Ross JENKINS, Andrew Edward WALLER, Daniel John GALLAGHER, Daniel Mark BAKER, Manoj Kumar TYAGI, Joseph CAVANAUGH

MULTILAYER INTEGRAL GEOGRIDS HAVING A CELLULAR LAYER STRUCTURE, AND METHODS OF MAKING AND USING SAME
Publication number: 20240026628Abstract: A multilayer integral geogrid, including one or more cellular layers, has a plurality of oriented multilayer strands interconnected by partially oriented multilayer junctions with an array of openings therein. The multilayer integral geogrid having one or more cellular layers is produced from a coextruded or laminated multilayer polymer starting sheet. The integral geogrid has a multilayer construction, with at least one outer layer thereof having the cellular structure. By virtue of the cellular layer structure, the multilayer integral geogrid provides for increased layer vertical compressibility under load, resulting in enhanced material properties that provide performance benefits to use of the multilayer integral geogrid to stabilize and strengthen soil, aggregates, or other particulate materials.Type: ApplicationFiled: July 26, 2023Publication date: January 25, 2024Applicant: Tensar International CorporationInventors: Joseph CAVANAUGH, Manoj Kumar TYAGI, Daniel Mark BAKER, Andrew CURSON, Tom-Ross JENKINS, Andrew Edward WALLER, Daniel John GALLAGHER -

Publication number: 20230278277Abstract: A monolayer multi-axial integral geogrid suitable for stabilizing aggregate includes a plurality of interconnected oriented strands and partially oriented junctions forming a repeating pattern of outer hexagons having an array of openings therein. Oriented ribs extending inwardly from each of said outer hexagons support and surround a smaller inner hexagon having oriented strands thus forming a plurality of trapezoidal openings and a single hexagonal opening. The oriented strands and partially oriented junctions of the outer hexagons form a plurality of linear strong axis strands that extend continuously throughout the entirety of the geogrid and form additional triangular openings. The geogrid thus includes three different repeating geometric shapes. The inner hexagons preferably also can move up and down, out of the plane of the geogrid. The multi-axial integral geogrid thus provides a geometry that can better engage with, confine and stabilize a greater variety and quality of aggregates.Type: ApplicationFiled: December 5, 2022Publication date: September 7, 2023Applicant: Tensar International CorporationInventors: Andrew CURSON, Tom-Ross JENKINS, Andrew Edward WALLER, Daniel John GALLAGHER, Daniel Mark BAKER, Manoj Kumar TYAGI, Joseph CAVANAUGH
