Soil Reinforcement Geogrids

When used in applications such as retaining walls and earth embankments, geogrids must have a resistance to “creep.”  Unlike traffic loading, the forces that act upon a geogrid in an earth retention structure are constant.  Polypropylene geogrids subjected to similar conditions will continue to stretch or “creep,” making the structure unsafe.  Soil Reinforcement Geogrids are made with the materials and processes that minimize creep making them well suited to such applications.

Most Soil Reinforcement Geogrids are uniaxial, meaning that they are considerably stronger in one direction versus the other.  It is important, when using a uniaxial geogrid to properly position the material so the higher strength direction is in line with the direction of the highest anticipated load.  GSI offers a wide variety of Soil Reinforcement Geogrids for a variety of applications.

Stratagrid® presents the latest development in geogrid technology. It is manufactured using advanced knitting procedures combined with a tough, proprietary method of PVC impregnation which penetrates into the high tenacity polyester yarns. Stratagrid® offers superior resistance to creep under constant stress, abrasion resistance, elevated temperature stability and excellent chemical and biological stability.
