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.
