Tensar® Uniaxial (UX) Geogrids are manufactured from select grades of high-density polyethylene (HDPE) resins that are highly oriented and resist elongation (creep) when subjected to heavy loads for long periods of time. These geogrids are also highly resistant to installation damage as well as long-term chemical or biological degradation. In fact, Tensar UX Geogrids have shown no degradation in soils with pH levels measuring as high as 12 and can be used in both dry and wet environments. Given the inert properties of HDPE resins, they can be installed with a variety of backfill materials, including on-site soils and recycled concrete.
Tensar UX Geogrids can carry high tensile loads applied in one direction (along the roll). Their open aperture structure interlocks with fill material to provide superior load transfer from soil to geogrid. These geogrids are manufactured by punching and drawing a homogenous polymer sheet to create a uniform product that does not require weaving, coating or welding to maintain structural integrity. This results in superior junction strength, which allows durable connection to other rolls of installed geogrid or to facing components.
Easy to handle and install, Tensar UX Geogrids are used for high-strength soil reinforcement in wall and slope applications; more than 100 million square feet of grade separation structures in service today are reinforced with them.
Biaxial Geogrids Tensar International invented and advanced the biaxial form of geogrid – the original geogrid. Tensar® BX Geogrids have been used for mechanical ground stabilization in over half a million projects worldwide, including roads, reinforced foundations and working platforms. Tensar BX Geogrids are created using precise blends of polypropylene, copolymers and additives to resist high, short-term dynamic loads or moderate loads over longer time periods.
Tensar® TriAx® Geogrid is an advanced product specifically designed for trafficked surfaces. TriAx Geogrid’s multi-directional properties leverage triangular geometry, one of construction’s most stable and widely utilized shapes, to provide an enhanced level of in-plane stiffness. Its triangular structure, coupled with improved rib and junction geometry, offers the construction industry an improved alternative to conventional materials and practices.
TriAx Geogrid is manufactured from a punched polypropylene sheet oriented in multiple, equilateral directions to form its triangular aperture, resulting in high radial stiffness throughout the full 360 degrees. This feature yields a more efficient product that delivers optimal in-service stress transfer from the aggregate to the stabilizing geogrid.
