Tensar FilterGrid

When stabilizing paved or unpaved structures, engineers and contractors must not only consider the appropriate geogrid product and thickness of granular fill, but also whether adequate filtration and separation of dissimilar materials will be maintained throughout the life of the structure. While Tensar geogrids frequently provide adequate confinement of the fill to achieve both filtration and separation, specifiers may sometimes recommend a geotextile in conjunction with the geogrid, particularly when low plasticity silts and clays present additional challenges. Tensar's FilterGrid™ solutions combine the superior performance of Tensar's InterAx® and TriAx® technology with the added assurance of a non-woven geotextile - all in a single composite product.

Benefits of FilterGrid: 

  • Multi-functional - provides aggregate stabilization, filtration and separation
  • Efficient installation - deploys as a single layer - saving time and labor costs
  • Economical - optimizes the structural thickness to save time and money
  • Eco-friendly - permanent, safe alternative to the use of chemical stabilization agents
