La description
A geogrid is geosynthetic material used to reinforce soils and
similar materials. Soils pull apart under tension. Compared to
soil, geogrids are strong in tension. This fact allows them to
transfer forces to a larger area of soil than would otherwise be
the case.[citation needed]
Geogrids are commonly made of polymer materials, such as
polyester, polyvinyl alcohol, polyethylene or polypropylene. They
may be woven or knitted from yarns, heat-welded from strips of
material, or produced by punching a regular pattern of holes in
sheets of material, then stretched into a grid.
The development of methods of preparing relatively rigid
polymeric materials by tensile drawing,[2] in a sense "cold
working," raised the possibility that such materials could be
used in the reinforcement of soils for walls, steep slopes,
roadway bases and foundation soils. The principal function of
geogrids is for reinforcement. This area, as with many other
geosynthetics, is very active, with a number of different
products, materials, configurations, etc., making up today's
geogrid market. 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 only is rib
strength important, but junction strength is also important. The
reason for this is that 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. The junctions are, of course, where the longitudinal
and transverse ribs meet and are connected. They are sometimes
called nodes. They are mainly used in Roads, Railways, Retaining
Wall structures, Slope Protection, Ground Improvement
applications.
