material used to reinforce soils and similar materials. There are two general types of geogrids uniaxial which are used most often to reinforce slopes or MSE walls and BiAxial which are most commonly used in roadways to perform sub grade improvement or base reinforcement. BiAxial geogrids have been used successfully in the civil construction market for over 25+ years and while there have been some advancements in the geogrid market the BiAxial geogrid continues to be the most economical solution today.
Some advantages of Biaxial geogrids are:
- low elongation
- very rigid material
- allows for interlock of soils
- reduces overall thickness of aggregates required
