Geogrids & Geotextile Fabrics
Sub-Grade Stabilization Geotextiles
Manufactured with high tensile strength and low elongations, our woven geotextiles have superior capacity for filtration, load distribution, reducing rutting and extending the life of paved and unpaved roadways. Made from individually woven, ultraviolet (UV) resistant polypropylene fibers, they provide dimensional stability and are resistant to UV degradation, biological and chemical environments normally found in soils. A non-woven geotextile can prevent subsurface soils from migrating through an erosion control system by relieving the hydrostatic pressure beneath it. When you’re facing separation, filtration, erosion protection and containment challenges, the use of geotextiles are the answer to these challenges.
Deploying a non-woven geotextile directly on the sub-grade extends road and railway life by preventing aggregate and ballast from being contaminated by intermixing finer soil particles. Non-woven geotextiles also work well in these applications, especially where “pumping” or extremely wet sub-grades occur.
Reinforcement & Retaining Wall Geosynthetics
We offer structural soil reinforcement geosynthetics through our line of woven geotextiles. Heavy polyester or polypropylene yarns are woven into unique patterns to form high strength geotextiles with superior hydraulic characteristics. These geotextiles maximize land use by allowing the construction of steeper slopes. Layers of structural geotextiles placed between soil lifts, allow the creation of steepened slopes by providing tensile strength to the soil system. When land space is limited, structural geotextiles are ideal for constructing retaining walls. These woven geotextiles provide a cost-effective alternative to traditional retaining wall construction methods.
Designed to protect shorelines from the devastation caused by coastal storms, high strength non-woven fabric tubes resist the erosive forces of nature. These high strength geotextile tubes are filled with dredged material or sand and installed on vulnerable shorelines to shield against wave action, high tides and long-shore currents. The placement of the geotextile tube covered with sand creates a resilient base for dunes to protect against erosion and storm damage.
Tensar bi-axial geogrids are created using select grades of polypropylene or copolymers that resist high, short-term dynamic loads or moderate loads over longer time periods. These products carry loads applied in any direction in the plane of the geogrid.
Tensar uni-axial geogrids are manufactured using select grades of high-density polyethylene (HDPE) resins that resist elongation (creep) when subjected to high loads for long periods of time. These geogrids carry large tensile loads applied in one direction (along the roll), and their open aperture structure interlocks with natural fill materials.
Tensar TriAx™ Geogrid
Ground-Breaking Technology for Building Economical, Long-Lasting Structures over Challenging Soils
TriAx™ geogrid delivers performance in three dimensions. Offering an innovative rib structure with near isotropic properties and advanced characteristics that improve upon the time-tested performance of Tensar’s industry-leading biaxial geogrid. Tensar TriAx™ geogrids permit construction on sites with weak soils eliminating all or most other foundation and/or soil stabilization work. These structural geogrids provide a reliable, cost effective method for increasing the stability of weak soils in a variety of applications including haul roads, intermodal facilities, military installation, railroads and industrial sites. By internally reinforcing all types of soils and construction fill material, Tensar TriAx™ geogrids create a stiffened, reinforced prism capable of supporting critical, engineered structures. With its unique triangular structure, TriAx™ Geogrid represents a revolutionary advancement in geogrid technology specifically developed for trafficked surfaces. Its multi-directional properties leverage the triangular geometry, one of construction’s most stable shapes, to provide a new level of in-plane stiffness. The transition from a rectangular to a triangular grid aperture, coupled with an increase in rib thickness and junction efficiency, offers the construction industry a better alternative to conventional materials and practices.
