I am working on mitigating housepads that were improperly constructed atop 15-20 feet of fill. Part of my recommendation was to remove several feet of soil, install a woven geotextile, and properly place and compact suitable fill material. Some of the "powers that be" at the site insist on removing 5' of material, install a NONwoven fabric, and place and compact fill material. I don't have much knowledge of strength/reinforcement characteristics of a nonwoven fabric (i typically use woven for such problems), will the nonwoven provide adequate strength? I should point out that there are many voids in the subsoil that the nonwoven fabric will have to bridge.
thank for the help
