About geogrids:

• It stands for a speedily emerging division inside the geotextiles area.
• Geogrids not in traditional textile form, it is in polymeric structure form.
• They work as reinforcement materials.
• Coated polyester geogrids have been broadly useful in soil steadiness andgeotechnical reinforcement uses.
• The geogrids are manufactured by extruding high density polyethylene or polypropylene & normally this geogrids are single or multilayer materials.
• The consequential netconstruction possesses large gaps well-known as apertures that increase the interaction with thesoil or aggregate.
• These apertures may vary in size from 1 to even more than 10 cm.

Product characteristics:

• Their physical structure can be categorized in to the following:
• Unidirectional geogrid: Having a great deal of tensile strength in one direction (longitudinal or transversal) than in the other direction.
• Bidirectional geogrid; Having identical strength in both longitudinal and transversal direction.
• Extruded geogrid: Created through stretching uniaxial or biaxial, an extruded integral structure.
• Bonded geogrid: Created through bonding, at right angles, two or more sets of strands.
• Woven geogrid: Created through interlacing, usually at right angles, two or more yarns, filaments or other elements.

Applications:

• Geogrids are mainly used for
• Reinforcement – beneath aggregate in unpaved roads,
• Reinforcement of embankment fills/earth dams,
• Repairing slope failures/landslides, as inserts between geotextiles/geomembranes etc.
