Biaxial geogrids and uniaxial geogrids are the prevailing types of geogrids. A geogrid is characterized as a geosynthetic material comprising interconnected parallel sets of tensile ribs with openings of adequate size to enable the infiltration of surrounding soil, stone, or other geotechnical materials (Koerner 1998). In simpler terms, geogrids can be described as plastic lattice structures with distinct technical properties and functions.
Uniaxial Geogrids find frequent application in scenarios demanding the mobilization of substantial long-term loads. Our Uniaxial Geogrids are manufactured using High Density Polyethylene (HDPE) and coated Polyester, ensuring durability and quality. We offer a diverse selection of Long Term Design Strengths to accommodate varying application and design specifications.
A biaxial geogrid is a bi-directional structure with two-way stretch which provides the same mechanical properties in two directions, both longitudinal and transverse. A uniaxial geogrid is a unidirectional structure with one-way stretch that provides stabilization in one direction only, mainly longitudinal.
What is uniaxial geogrid?
A uniaxial geogrid is a unidirectional structure with one-way stretch that provides stabilization in one direction only, mainly longitudinal. Each is used in specific civil engineering applications depending on the desired reinforcement and stabilization outcomes.
What are the three types of geogrid?
There are four types of geogrids Uniaxial, Biaxial, Triaxial (Triax®) and Geogrid-Geotextile Composites.
What is the application of uniaxial geogrid?
Given their unique properties, Uniaxial geogrids are ideal for both wall and slope applications such as retaining walls, landfill liner systems, embankments over soft soils, and very steep earthen slopes. Uniaxial Geogrids are designed to provide strength in a single direction, hence the prefix “Uni”.
What does a biaxial geogrid do?
Biaxial Geogrid
Biaxial geogrids are designed to have an equal balance of tensile strength in both machine and cross directions. This gives the geogrid the ability to distribute loads over a wider area than usual which increases its capacity in base stabilization applications.
Each is used in specific civil engineering applications depending on the desired reinforcement and stabilization outcomes. Biaxial geogrids allow for wider load distribution making them ideal for the construction of roads, working platforms, or preparation of site subgrades where base stabilization is needed in two directions; while uniaxial geogrids are best used in the construction of structures with a vertical component like earth retaining walls and steep soil slopes. This geogrid provides reinforcement in one direction.
