I-Geotextile ityhubhu ilungele iiprojekthi zonyango lwe-sludge.Inkunkuma i-slurries ijikeleziswa kwaye imponlwe ngokuthe ngqo kwiityhubhu ze-geotextile ezikhupha amanzi ezahlula inkunkuma yolwelo kwizinto eziqinileyo.Ityhubhu ye-geotextile inokucoca okuphezulu kunye namandla okuqina, alungele ukukhupha amanzi ngodaka.Le nkqubo inciphisa umthamo wenkunkuma;ukunciphisa iindleko kunye nexesha lokuthuthwa kodaka ukuya kwindawo yokulahla.
