Separation & Stabilization

Separation and stabilization geotextiles have been used successfully on private and public projects throughout the United States for decades. State Departments of Transportation and organizations such as FHWA (Federal Highway Administration) and AASHTO (American Association of State Highway & Transportation Officials) all have standardized geotextile specifications for separation and stabilization.

Typically, a woven slit-film geotextile is the preferred choice, due to their high-strength and low cost. Heavier weight nonwoven geotextiles are sometimes utilized in areas with standing water or high water tables. US Fabrics offers a wide variety of woven and nonwoven separation and stabilization geotextiles with varying strengths and hydraulic characteristics. Such a wide variety allows the designer to choose the product that best matches the project needs.

  • Decades of Success Private & Public

  • Wide Variety
  • Woven Slit-Film Most Common
  • Nonwovens When Water Is An Issue
  • Geotextiles Preferred Over Geogrids
  • Woven Slit-Films Separate Better

Geotextile vs. Geogrids

Base stabilization geogrids are popular among engineers, but do not provide the separation of a geotextile. Geotextiles are a solid sheet, while geogrids have openings and must rely on mechanical interlock with the aggregate to provide separation. In a few instances, a geogrid is preferred, but often must be utilized with a geotextile to provide proper separation. While US Fabrics has base stabilization geogrids, we believe in woven slit-film geotextiles for most road and parking lot stabilization/separation applications.
