I-HDPE i-geomembrane egudileyo iphantsi kakhulu yokungena kwi-membrane liner okanye umqobo onomphezulu ogudileyo. Ingasetyenziswa kuphela okanye nayo nayiphi na imathiriyeli enxulumene nobunjineli be-geotechnical ukulawula ukufuduka kwamanzi (okanye igesi) kwiprojekthi eyenziwe ngumntu, isakhiwo, okanye inkqubo. Ukuveliswa kwe-HDPE geomembrane egudileyo iqala ngokuveliswa kwezinto eziluhlaza, ezibandakanya ikakhulu i-HDPE polymer resin, kunye nezongezo ezahlukeneyo ezifana nekhabhoni emnyama, i-antioxidants, i-anti-aging agent, i-UV absorber, kunye nezinye izinto ezincedisayo. I-resin ye-HDPE kunye ne-additives ratio yi-97.5: 2.5.
