Geogrid is a polymeric material made up of many polymers like polyethylene, polyvinyl alcohol polypropylene etc. It is one of the most important
inventions in geo synthetics which is used as a reinforcing material. They formed by joining intersecting ribs. They have large open spaces in
between the ribs known as “apertures”.
Geogrids can be classified in to two layers based on the stress transfer or direction of stretching during manufacture as –
1. Uniaxial Geogrid – It is stretched only along longitudinal direction. Thus the stress is transferred only along that axis; even the tensile
strength is more in longitudinal direction compared to transverse direction.
2. Biaxial Geogrid – It is stretched along two directions (longitudinal and transverse), thus the stress is equally distributed along both
|Promotes soil stabilization.

Frequently Asked Questions
Geogrids work by interlocking with the granular or soil material placed over them. The apertures allow for strike-through of
the cover soil material which then interlock with the ribs (flat straps/bars) Providing confinement of the overlaying
granular/soil material due to the stiffness and strength of ribs.
geogrid use for walls taller than three to four feet. If there are steep slopes near the wall, loading above the wall, tiered
walls or poor soils, then even shorter walls may need geogrid.
Geogrids are manufactured specifically as a reinforcement material, whereas geotextiles have other functions, such as
separation, drainage, and filtration.
Biaxial Geogrid with Excellent Reinforced Performance. Biaxial geogrid is a type of geogrids. It is made from high polymer.
Biaxial geogrid has high strength in both longitudinal and transverse direction. It is made through the process of extruding,
sheet forming, punching and stretching.
