Publication number: 20250237032Abstract: Aspects of a method for stabilizing geotechnical environments involves the use of a substantially planar geogrid featuring primary and secondary nodes, non-continuous ribs terminating at secondary nodes, continuous ribs intersecting at primary nodes, and a compressible cellular layer. The method includes trapping varied aggregate within confinement elements formed by the nodes and ribs, and compressing the aggregate against the compressible cellular layer. This compression embeds the aggregate into the cellular layer, effectively locking it in place and enhancing the stability of the geotechnical environment. The design of the geogrid and the interaction between the aggregate and the compressible layer provide improved load distribution and resistance to environmental stresses and trafficking.Type: ApplicationFiled: April 8, 2025Publication date: July 24, 2025Applicant: Tensar International CorporationInventors: Andrew CURSON, Tom Ross JENKINS, Andrew Edward WALLER, Daniel John GALLAGHER, Daniel Mark BAKER, Manoj Kumar TYAGI, Joseph CAVANAUGH

Publication number: 20250230620Abstract: An expanded multilayer integral geogrid includes a plurality of oriented strands interconnected by partially oriented junctions having an array of openings therein that is produced from a coextruded or laminated multilayer polymer starting sheet. The integral geogrid has a multilayer construction, with at least one inner layer thereof having a structure that is expanded relative to at least one other layer of the multiple layers. By virtue of the expanded inner layer structure, the expanded multilayer integral geogrid provides for increased layer compressibility under load, resulting in enhanced material properties that provide performance benefits to use of the expanded multilayer integral geogrid in soil geosynthetic reinforcement, and economic benefits compared to a like integral geogrid without an expanded inner layer structure.Type: ApplicationFiled: April 2, 2025Publication date: July 17, 2025Applicant: Tensar International CorporationInventors: Andrew CURSON, Tom-Ross JENKINS, Andrew Edward WALLER, Daniel John GALLAGHER, Daniel Mark BAKER, Manoj Kumar TYAGI, Joseph CAVANAUGH

Publication number: 20250187257Abstract: 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 17, 2024Publication date: June 12, 2025Applicant: Tensar International CorporationInventors: Andrew CURSON, Tom-Ross JENKINS, Andrew Edward WALLER, Daniel John GALLAGHER, Daniel Mark BAKER, Manoj Kumar TYAGI, Joseph CAVANAUGH
