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 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. |  |
| Synteen SF® Geogrids are woven under tension, of high tenacity polyester yarns. The yarns are coated with a PVC material to resist biological degradation. This combined process gives Synteen SF® Geogrids a high resistance to "creep" making them well suited for use where high loads are constant such as mechanically stabilized earth (MSE) walls and embankments. |

| Synteen® also offers Biaxial SF Geogrids. These products are perfect for applications where forces may act upon the grid from a variety of directions such as widening a road over soft soils, or adding a turn lane. Forces from traffic loads in these situations are generally perpendicular to the direction of the widening. Because they are manufactured from the same high tenacity, coated polyester yarns, Synteen® Biaxial SF Geogrids offer the same long-term resistance to creep as the Uniaxial SF Geogrids. |

| 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. |
