Soil Stabilization Geogrids

Biaxial is a term given to geogrids with relatively similar strength properties in both directions, with the length of the roll and across the roll. In soil stabilization applications, Biaxial Polypropylene Geogrids are commonly used to improve the performance of weak subgrades. By distributing dynamic loads over a wider area, pumping and shear failures are minimized, resulting in increased load bearing capacity of the subgrade. Biaxial Polypropylene Geogrids are also very effective in base reinforcement applications. The openings in the geogrid interact with base materials, confining them and preventing lateral dispersion. The result can be up to a 30% reduction in base course materials. GSI offers a full array of Biaxial Polypropylene Geogrids.

Tenax MS® Biaxial Geogrids are made from bonding multiple layers of high strength, biaxially oriented polypropylene grids. Layering the grids creates the unique array of random apertures and maximizes the number of tensile elements. The random apertures and large number of tensile elements allows for greater soil interaction with more types of soils.

The random apertures created from the multi layer construction of Tenax MS® Geogrids are designed to accommodate a variety of fill materials.

Tensar BX® Geogrids are created using select grades of polypropylene or copolymers that resist high, short-term dynamic loads or moderate loads over longer time periods. Their single layer, open aperture structures interlock with natural fill materials. Tensar BX1100 and BX1200 Geogrids have slightly higher strength values across the roll. This can be desirable when traffic will travel in the length of the roll direction. Tensar BX4100 and BX4200 Geogrids have similar strength in both directions, making them suitable where traffic is random.

In soil stabilization applications, Biaxial Polypropylene Geogrids distribute loads over a larger area, reducing pumping and shear failures while maximizing the load bearing capacity of the subgrade.

In base reinforcement applications, Biaxial Polypropylene Geogrids prevent lateral dispersion of base materials improving their structural performance. This can result in up to a 30% reduction in base course materials.
