Introduction:

Geogrids are polymeric products formed by joining intersecting ribs. They have large open spaces known as "apertures". The directions of the ribs are referred to as machine direction (md), orientated in the direction of the manufacturing process or cross machine direction (cmd) perpendicular to the machine direction ribs. Geogrids are mainly made from polymeric materials, typically polypropylene (PP), high density polyethylene (HDPE) and polyester (PET). Geogrids are manufactured as either biaxial or uniaxial. Biaxial geogrids are those that exhibit the same strength in both the machine and cross machine directions while uniaxial geogrids exhibit the primary strength in the machine direction with minimal strength, enough to maintain the aperture structure, in the cross machine direction.

Function of Geogrid:

Basic function of Geogrid is soil reinforcement. Geogrids work by interlocking with the granular or soil material placed over them.

Reinforcement:

The mechanical properties of Geogrids, make them ideal for reinforcing slopes and other soil structures.

• To avoid collapse of vertical soil walls or steep soil slopes.
• To avoid rutting when dealing with poor subsoils.
