Geogrids are products made of a geosynthentic cloth, used to protect, support and reinforce soils and similar materials. They are widely used to provide reinforcement for maintaining partitions, as well as subsoils beneath roads and other engineering structures.
Geogrids are made from synthetic materials, such as plastic, and have been designed primarily to provide mechanical stability to soil, earth and other granular substances. They are strong and provide a source of tension, which in turn provides support to hold the underlying material together. The manufacture and installation of geogrids, or road grids, does not require traditional construction methods to be undertaken, such as foundation excavation
Geogrids, also known as road grids, are most commonly made of polymer materials - for example, polyester, polyvinyl alcohol, polyethylene or polypropylene. The textiles used to fabricate geogrids can be woven or knitted from yarns, heat-welded from strips of material, or produced by systematically punching a pattern of holes in sheets of material, then stretched into a grid.
Geogrids possess a high level of elasticity, allowing them to hold tension. They also provide a good amount of junction strength, and are resistant to damage during installation. Additionally, they are chemically unreactive and therefore resistant to corrosion, due to the fact that they are made from high density polyethylene, which is completely resistant to chemical and biological factors that naturally occur in soils.
Geogrids are commonly used to reinforce retaining walls, as well as subbases or
subsoils below roads or structures.
Common applications include:
● Embankments and soft soils
● Erosion control and management
● Highway infrastructure
● Roadway infrastructure
● Reinforced slopes
● Retaining walls
● Energy systems
● Acoustic barriers
● Construction projects
● Repair and prevention of landslides
● Construction and improvement of rail and road embankments
