Perhaps one of the most useful tools for environmental and construction projects is geogrid. Geogrids are geosynthetics made from a polymeric material, created by weaving or knitting intersecting ribs with designated apertures (gaps for the ribs to fit into). Thanks to their increased ability to distribute loads across large areas and perform under pressure, geogrids are often used in construction or separation applications. However, there are many other geogrid applications to explore across varying industries.
Types of Geogrid
Before diving into geogrid applications, it`s important to understand that there are different types of geogrid, which each lend themselves to varying applications. For the most part, There are two ways that geogrids can be categorized: by pattern and manufacturing.
GEOGRIDS BY PATTERN
Uniaxial geogrids are known as mono-oriented geogrids. They utilize a flat planar grid, which results in a much higher strength in one direction than in the other direction. They are perfect for both wall and slope applications including retaining walls, landfill liner systems, embankments over soft soiled, and extra steep earthwork slopes.
Biaxial Geogrids are known as bi-oriented geogrids. They also utilize a planar grid, which possesses similar strength in both ortho-directions (longitudinal and transversal). They are commonly used in applications including foundations for roadbeds, railroad truck beds, permanent unpaved roads, airport runways, construction haul roads, working platforms on weak subgrades, and parking lots.
Triaxial geogrids are manufactured from punched polypropylene sheets oriented in multiple equilateral directions to form triangular apertures. They deliver optimal in-service stress transfer from aggregate to geogrid and are typically used in asphalt pavement, soft soil reinforcement, roadbed, subgrade, and retaining wall applications.
Extruded geogrid are flat polymer structures that are extruded and then pulled in either one direction or two main directions. They are often used for ground stabilization and soil reinforcement applications.
Woven geogrid is manufactured by grouping polymeric or polypropylene and weaving them into a mesh pattern. They are usually used for stabilization and retaining wall reinforcement applications.
Bonded geogrid is produced by bonding two or more sets of strands or other elements, typically at right angles. They are typically used for sub grade and environmental applications.
