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.
