Spec InterpretationHeavy 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. A heavy weight nonwoven geotextile can be used as a geomembrane cushion. Placing a nonwoven geotextile above or below the geomembrane helps protect it from punctures.
Heavy weight nonwoven geotextiles are also used for railroad stabilization. When placed under track, nonwoven geotextiles prevent intermixing of the ballast with the soil below. 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.
Nonwoven geotextiles heavier than 16 oz are available. If your specification calls for a heavier nonwoven, please give us a call. US Fabrics also offers Stall Mat, a 26 oz/sy nonwoven geotextile with extra heat applied to one side to create a permeable, tough mat for usage in horse stalls.
