What nonwovens do you recommend to protect a geomembrane liner?

A properly selected nonwoven, needle-punched geotextile can protect a liner from damage. US Fabrics cannot recommend a nonwoven geotextile for a specific project. However, a heavyweight (10 oz or higher) nonwoven geotextile is typically specified. Please refer to the project specifications.

What nonwovens work best under railroad ballast?

AREMA has developed a specification for railroad ballast separation. Please refer to our AREMA Section Guide for the correct product.

Are your heavy weight nonwoven filtration geotextiles NTPEP compliant?

We offer NTPEP compliant heavy weight nonwoven geotextiles. Each individual product data sheet will indicate if it is NTPEP approved and list the GTX number

What is an environmental nonwoven geotextile?

An environmental nonwoven is a product that is manufactured to achieve the desired thicknesses and strengths for optimal performance in the critical application of landfill geomembrane protection. These products are more expensive than standard civil nonwovens.

Heavy Weight Nonwoven Geotextiles

US Fabrics' heavy weight nonwoven geotextiles (10 oz. to 16 oz.) are made from staple filaments of polypropylene fiber and are needlepunched and heat set.

  • 10.0 – 16.0 oz/sy
  • NTPEP Approved Fabrics
  • Geomembrane Cushion
  • AREMA Grade Geotextiles
  • Permanent Erosion Control

A heavy weight nonwoven geotextile can be used as a geomembrane cushion in civil applications such as retention/detention ponds. Placing a nonwoven geotextile above or below the impermeable geomembrane helps protect it from punctures.

They are also effective for permanent erosion control applications utilizing large rip-rap and/or requiring extreme drop heights.

Heavy weight nonwoven geotextiles are also used for railroad stabilization. When placed under track, heavyweight nonwoven geotextiles prevent intermixing of the ballast with the soil below. And unlike a geogrid, they can withstand the abrasion.

The American Railway Engineering and Maintenance-of-Way Association (AREMA) recommends a 10-12 oz nonwoven geotextile for regular applications; a 12-16 oz nonwoven geotextile for heavy applications; and a 16-20 oz nonwoven geotextile for extra heavy applications.

MARV Weight Environmental Nonwovens

Nonwoven geotextiles heavier than 16 oz are available. These are M.A.R.V. weight products that are used exclusively in the environmental market. If your landfill project requires these products please take a look at our environmental nonwoven geotextiles.
