Geogrids are specialized geosynthetics widely used in the civil engineering projects to stabilize and reinforce soil, especially steep slopes of embankments. They are made of various polymers and may be welded from strips, extruded, woven or knitted from yarns. Geogrids are characterized by a tensile strength from 20 to 400 kN/m. They guarantee a significant increase in ground bearing capacity. They can be designed for up to a 120-year service life, and they are resistant to chemical and biological corrosion.
Geogrids can also be used as a part of geocomposites in combination with non-woven geotextile: the former reinforces the soil, while the latter separates and filtrates it. Choosing such a solution saves installation costs and makes it more efficient for soft soils.
