Geogrids are used almost/entirely for soil reinforcement. Their
large aperture size limits their effectiveness as a filtration
layer but their high tensile strength make them ideal for
reinforcement applications such as base reinforcement and soft
soil stabilization. Geogrids are manufactured using application
specific grades of polyolefin resins (high–density polyethylene
or polypropylene). Depending upon manufacturing techniques and
materials, geogrids can be designed to resist creep when
subjected to high loads for long periods of time or resist high,
short–term dynamic loads or moderate loads over longer periods
of time. Uniaxial geogrids are designed to/endure stress in one
direction. The ribs of this variety of geotextile tend to be
thicker and the apertures are long narrow slits. This variety of
grid tends to be stronger than biaxial, but can only be applied
in situations where stresses occur in a single direction (unless
two uniaxial grids are placed in opposite directions). Biaxial
geogrids can take
