NONWOVEN GEOTEXTILES

Nonwoven Geotextile

Nonwoven geotextiles are designed to filter soil particles from drainage systems, and stabilize roadways to increase the performance life of these structures.

Whether constructing a roadway, designing an erosion control plan or installing a subsurface drainage system, you can count on the proven benefits of Geotex needle-punched nonwoven geotextiles. Nonwoven geotextiles are approved by many local, state and federal agencies, including the Federal Highway Administration, U.S. Army Corps of Engineers, the Environmental Protection Agency and AASHTO. Nonwovens are ideal for a variety of civil engineering applications, including:


Subsurface Drainage

Lightweight and medium weight nonwoven geotextiles prove to be excellent filters in subsurface drainage applications. The needle punch construction of the fabric allows subsurface water to pass into the drainage pipe for proper channeling. At the same time, the nonwoven prevents adjacent soil from clogging the system and causing costly excavation and repair. When properly selected, nonwoven geotextiles are effective in most soils, particularly in environments where silt and clay are prominent.

Roadway Separation/Railroad Stabilization

Deploying a Nonwoven geotextile directly on subgrades extends road life by preventing fine subgrade soil particles from migrating and intermixing into the aggregate and ballast base course. 401 meets AASHTO M288 Class 3 standards, and 801 exceeds the requirements for Class 1 textiles used in roadways.

Hard Armor Underlayment

Soil migration and the buildup of hydrostatic pressure are two of the leading causes of failure in hard armor, such as rock riprap and concrete block systems, along shorelines and waterways. Nonwoven geotextiles act as a filter to help prevent subsurface soil migration and relieve hydrostatic pressure beneath hard armor erosion control systems. 801 and 401 meet the requirements for Class 1 and Class 3 erosion control geotextiles, respectively, as outlined in AASHTO M288.

Landfill Leachate Collection

When placed in intimate contact with a geonet or drainage stone, medium weight Nonwoven geotextiles can filter soil and waste while allowing water and leachate to pass. An efficient design utilizing recommended Nonwoven geotextiles can lead to proper leachate management in new landfill cells, and rapid surface water collection and removal in closure plans.

Subsurface Retention/ Detention Systems

Underground storm water retention systems incorporate large diameter pipe to hold runoff in a defined area until the surrounding soil can accept it. Detention systems, on the other hand, consist of large diameter pipe that detains all runoff exceeding the allowable amount and releases it through an outlet pipe at a controlled rate. Some systems are a combination of both. In each case, subsurface retention/detention systems provide maximum use of land, require little maintenance, and do not diminish the aesthetics of the development.

Geomembrane Protection

Heavyweight and ultra-heavyweight Nonwoven geotextiles cushion and protect geomembranes from damage by sharp objects, elevating puncture, impact and abrasion resistance. Nonwoven geotextiles up to 1350gr/m2 (40 oz/yd2) are also available for the most challenging applications

Gas Collection

Heavyweight and ultra-heavyweight Nonwoven geotextiles provide collection and lateral transmission of liquids and gasses that may build up beneath flexible geomembranes used in the closure and capping of waste facilities.

Asphalt Overlays

Pave-Dry® nonwoven geotextiles are specifically engineered for asphalt overlays. Pave-Dry Geotextiles are installed during rehabilitation as a fabric interlayer between the old and new asphalt layers inflexible pavement systems. Because polypropylene has an affinity for petroleum products, tack coats easily migrate into the fibers. This creates an inert, laminated composite that has proven to extend roadway life an average of 3 to 7 years.
