I-Geomembrane iyimpahla engangeni manzi nesithiyo esekelwe ezintweni eziphezulu ze-polymer. Ihlukaniswe kakhulu i-polyethylene (LDPE) geomembrane, i-high-density polyethylene (HDPE) geomembrane, ne-EVA geomembrane. I-warp knitted composite geomembrane ihlukile kuma-geomembranes ajwayelekile. Isici sawo ukuthi ukuphambana kwe-longitude ne-latitude akugobile, futhi ngayinye isesimweni esiqondile. Bopha lezi ezimbili ngokuqinile ngentambo ephothiweyo, engavumelaniswa ngokulinganayo, imelane namandla angaphandle, ukusabalalisa ukucindezeleka, futhi lapho amandla angaphandle asetshenziswayo edabula impahla, intambo izoqoqa eduze nokuqhekeka kokuqala, okwandisa ukumelana nokukhala. Uma kusetshenziswa inhlanganisela elukiwe ye-warp elukiweyo, intambo elukiweyo ilukiwe kaningi phakathi kwezingqimba zefiber ye-warp, weft, ne-geotextile ukuze kwelukwe kokuthathu kube yinto eyodwa. Ngakho-ke, i-warp knitted composite geomembrane inezici zamandla aqinile aphezulu kanye nobude obuphansi, kanye nokusebenza okungangeni kwamanzi kwe-geomembrane. Ngakho-ke, i-warp knitted composite geomembrane iwuhlobo lwento emelene ne-seepage enemisebenzi yokuqinisa, ukuhlukanisa, nokuvikela. Kuwukusetshenziswa kwezinga eliphezulu kwezinto eziyinhlanganisela ye-geosynthetic emhlabeni jikelele namuhla.

Amandla aqinile aqinile, ubude obuphansi, ukuguquguquka okufanayo kobude nokuguquguquka, ukumelana nezinyembezi eziphakeme, ukumelana kahle nokugqokwa, nokumelana namanzi okuqinile. indwangu elukiwe. Ukusebenza kwayo kwe-anti-seepage ikakhulukazi kuncike ekusebenzeni kwe-anti-seepage yefilimu yepulasitiki. Amafilimu epulasitiki asetshenziselwa izinhlelo eziphikisana nokubona ikhasi ekhaya nakwamanye amazwe ikakhulukazi afaka i-(PVC) i-polyethylene (PE) ne-ethylene/vinyl acetate copolymer (EVA). Ziyizinto eziguquguqukayo zamakhemikhali e-polymer ezinamandla adonsela phansi athile, ukunwebeka okuqinile, ukuguquguquka okuphezulu kokuguquguquka, ukumelana nokugqwala, ukumelana nezinga lokushisa eliphansi, nokumelana nesithwathwa okuhle. Impilo yesevisi yefilimu ye-geotextile eyinhlanganisela inqunywa ngokuyinhloko ukuthi ifilimu yepulasitiki ilahlekelwe yini umsebenzi wayo wokulwa nokubona kanye nokuvimbela amanzi. Ngokwezindinganiso zikazwelonke zeSoviet Union, ifilimu ye-polyethylene enobukhulu obungu-0.2m kanye ne-stabilizer esetshenziselwa ubunjiniyela be-hydraulic ingasebenza iminyaka engu-40-50 ngaphansi kwezimo zamanzi acacile kanye neminyaka engu-30-40 ngaphansi kwezimo zokukhucululwa kwendle. Ngakho-ke, impilo yesevisi ye-geomembrane eyinhlanganisela yanele ukuhlangabezana nezidingo zokunqanda ukuphuma kwedamu.
