WINFAB 300NP is a needlepunched nonwoven geotextile manufactured using polypropylene fibers that form a dimensionally stable network, which allows the fibers to maintain their relative position. WINFAB 300NP resists ultraviolet deterioration, rotting, and biological degradation and is inert to commonly encountered soil chemicals. WINFAB 300NP is heat-set and designed specifically for asphalt overlay applications.
