Road Construction Slope Protection Filter Layer Long Fibre Needle Punched Geotextile Fabric
Needle Punched Geotextile Fabric Description
Nonwoven fabrics are made by extruding continuous filaments of polypropylene which are then cut, opened, laid into a web, needle-punched, heat-set and rolled into the finished product. These 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.
