JP Geotex Grids are made from polyester knitted high tenacity yarn coated with UV stabalized polymeric compound. Our Geogrids are available with different opening sizes between the adjacent sets of longitudinal and transverse ribs large enough to allow soil strike-through from one side of the geogrid to the other. Hence in anchorage situations the soil strike-through within the apertures bears against the transverse ribs, which transmits the load to the longitudinal ribs via the junctions.
Geogrids are strong in tension. This fact allows them to transfer forces to a larger area of soil than would otherwise be the case since soils pull apart under tension.
