Woven Geotextiles
For Soil Separation, Stabilization and Reinforcement Applications Including:

  • Paved and Unpaved Roadways
  • Airport Runways and Taxiways
  • Haul Roads at Waste Containment Facilities

Hundreds of Millions of Square Yards Installed

After extruding and slitting a polypropylene film, our ISO 9002-certified manufacturing process weaves individual yarns into geotextiles featuring high tensile strengths at low elongations (high tensile modulus). These characteristics allow Geotex® woven geotextiles to distribute loads, reduce rutting and extend the life of paved and unpaved roadways.

Unpaved Roadways

Geotex woven geotextiles help save on aggregate placement and repair costs associated with constructing and maintaining unpaved roadways. Characterized by soft subgrades, high traffic loads and large deformation tolerances, typical unpaved roads often require upkeep. A soft subgrade covered with the appropriate Geotex woven geotextile stabilizes an access or haul road by spreading applied loads over a wider foundation, reducing rut depths and preventing aggregate contamination by the underlying subgrade soils. This reduces maintenance costs, improves roadway life and permits unrestricted flow of traffic.

Geotextile Functions

Depending upon the actual strength of the subgrade, Geotex woven geotextiles have the ability to perform several different functions. These range from Reinforcement on weak subgrades (CBR<3%) to Separation on firm foundation soils (CBR>8%). As expected, weaker subgrades demand stronger woven geotextiles and more favorable soils require less robust geotextiles.

Paved Roadways

The "ST" series of Geotex® woven geotextiles offer an inexpensive and time-proven means of extending the life of paved roadways and parking lots. Since subgrade contamination is the leading cause of pavement failure, highway engineers typically thicken aggregate layers using sacrificial aggregate to offset the expected losses. By unrolling a high modulus Geotex woven geotextile directly on the subgrade during construction, aggregate is permanently separated from finer soils below. This prevents intrusion of the subgrade into the aggregate and improves the subsurface drainage of roadways. Even when the rigors of heavy truck traffic pound the pavement, a Geotex woven geotextile allows aggregate layers to maintain their original design thickness.

Woven Selection Guide

Geotex 180ST, 250ST and 315ST meet the American Association of State Highway Transportation Officials (AASHTO) M288-00 construction requirements. For more demanding soil reinforcement applications exceeding the AASHTO criteria, we offer high strength woven geotextiles.

High Strength Wovens

When you encounter very soft soils or other critical soil reinforcement applications, request technical literature on our full line of high strength geotextiles. Their unique twill weave forms a robust fabric with high tensile strengths and superior hydraulic characteristics.

Wovens for Sediment Control

Once fastened to posts and properly installed, Geotex® woven geotextiles are also effective in controlling sediment-laden runoff from construction sites. These woven silt fence fabrics offer a unique combination of UV resistance, strength and hydraulic properties.
