Does the manufacturer have a spec? Icpi filter fabric non woven geotech is optional on as a sub base seperator on permeables. The stone layers choke each other out. On some jobs we did run filter fabric on the 3/4 clean and run bedding sand for non permeable pavers. Adding fabric changes the water infiltration rates.
