Nau'in Geotextile
Geotextile wani nau'i ne na geotextile mai lalacewa wanda aka yi da zaren polymer ta hanyar danna zafi, siminti da saƙa, wanda kuma aka sani da geotextile, gami da saƙa da saƙa.
Kayayyakin saƙa na Geotextile sun haɗa da saƙa (saƙa na fili, saƙa zagaye), saka (saƙa ta fili, twill), saka (saƙan warp, saka allura) da sauran hanyoyin samarwa.
Geotextiles da ba a saka ba sun haɗa da hanyoyin samarwa kamar hanyar ƙarfafa injina (hanyar acupuncture, hanyar huda ruwa), hanyar haɗaɗɗiyar sinadarai (hanyar spraying manna, hanyar impregnation), hanyar haɗin narke mai zafi (hanyar mirgina mai zafi, hanyar iska mai zafi), da sauransu.
