Composite Geogrids

Tensar FilterGrid™ combines the stabilization benefits of geogrid with the separation and filtration advantages of nonwoven geotextile fabric

Stabilize working surfaces, such as paved and unpaved roadways, airfields, crane pads, and more, with Composite Geogrids. This high-quality geosynthetic combines the superior performance of geogrid with the separation capabilities of a nonwoven geotextile by laminating the two technologies together. Combining these technologies is especially important when dealing with worksites that have low-plasticity soil or clay subgrades. As a result, construction professionals and engineers benefit from aggregate stabilization and confinement, filtration, and separation, further optimizing structural thickness and saving both time and money stabilizing subgrades.

Key benefits of FilterGrid

FilterGrid’s unique structure provides a high degree of in-plane stiffness. This is achieved through a mechanism known as lateral restraint. To explain, lateral restraint is the ability to confine and stabilize aggregate particles within the plane of the geogrid. Therefore, as granular base courses are stress-dependent materials, the confinement offered by properly designed, stiff geogrids improves the modulus of aggregate material and load distribution. In addition, it maintains its modulus over a much longer period in comparison to an unstabilized aggregate. Once deployed, the geotextile component of the composite geogrid prevents fines from migrating into your base material and contaminating the integrity of the fill. Overall, this confinement improves the speed of construction, reduces fill requirements, and enhances the performance and durability of these working structures.
