I-HDPE geomembrane bushelelezi iphansi kakhulu i-membrane yangaphandle ekwazi ukufinyeleleka liner noma umgoqo onendawo ebushelelezi. Ingasetshenziswa kuphela noma nganoma iyiphi into ehlobene nobunjiniyela be-geotechnical ukuze kulawulwe ukufuduka koketshezi (noma igesi) kuphrojekthi eyenziwe ngumuntu, isakhiwo, noma isistimu. Ukukhiqizwa kwe-HDPE geomembrane bushelelezi kuqala ngokukhiqizwa kwezinto ezingavuthiwe, ezihlanganisa ikakhulukazi i-HDPE polymer resin, nezithasiselo ezihlukahlukene ezifana ne-carbon black, ama-antioxidants, i-anti-aging agent, i-UV absorber, nezinye i-adjuvant. I-HDPE resin ne-additive ratio ingu-97.5:2.5.
