Geogrids represent a rapidly growing segment within geosynthetics. Rather than being a woven, nonwoven or knitted textile fabric, geogrids are polymers formed into a very open, gridlike configuration, i.e., they have large apertures between individual ribs in the transverse and longitudinal directions.
The key feature of all geogrids is that the openings between the adjacent sets of longitudinal and transverse ribs, called “apertures,” are large enough to allow for soil strike-through from one side of the geogrid to the other. The ribs of some geogrids are often quite stiff compared to the fibers of geotextiles. As discussed later, not ...

A needle-punched nonwoven geotextile bonded to a geogrid provides in-plane drainage while the geogrid provides tensile reinforcement. Such geotextile-geogrid composites are used for internal drainage of low-permeability backfill soils for reinforced walls and slopes.
The Walpole Company, Indiana Company, and members of the Ohio Company reorganized, and on December 22, 1769, formed the Grand Ohio Company. [14] In 1772, the Grand Ohio Company received from the British government a grant of a large tract lying along the southern bank of the Ohio as far west as the mouth of the Scioto River . [ 15 ]
