I-Geomembrane iyinto engangeni manzi futhi iyisithiyo esekelwe kuma-polymer anesisindo samangqamuzana aphezulu. Ihlukaniswe kakhulu ngama-geomembranes e-polyethylene (LDPE) e-low-density polyethylene (HDPE), kanye nama-geomembranes e-EVA. I-geomembrane eyinhlanganisela eyakhiwe ihlukile kuma-geomembranes ajwayelekile. Isici sayo ukuthi ukuphambana kwemigqa ye-longitude ne-latitude ayigobile, futhi ngamunye usesimweni esiqondile. Ukusebenzisa intambo eboshiwe ukuze ubophe ngokuqinile kokubili kungafinyelela ukuvumelanisa okufanayo, ukumelana namandla angaphandle, ukusabalalisa ukucindezeleka, futhi lapho amandla angaphandle asetshenziswayo edabula impahla, intambo izoqoqana eduze nokuqhekeka kokuqala, okwandisa ukumelana nezinyembezi. Phakathi nenhlanganisela yokuluka i-warp, intambo yokuluka idluliswa ngokuphindaphindiwe phakathi kwezingqimba ze-warp, weft, kanye nefiber ye-geomembrane ukuze kweluke lezi zintathu zibe yinto eyodwa. Ngakho-ke, ama-geomembranes ayinhlanganisela ye-warp knitted awagcini nje ngokuba nezici zamandla aqinile aphezulu kanye nobude obuphansi, kodwa futhi anokusebenza okungangeni kwamanzi kwama-geomembranes. Ngakho-ke, i-warp knitted composite geomembrane iwumsebenzi omelene namakhasi anemisebenzi yokuqinisa, ukuhlukanisa, nokuvikela. Kuwuhlelo oluthuthuke kakhulu lwezinto 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. Ukusebenza kwayo kwe-anti-seepage ikakhulukazi kuncike ekusebenzeni kwe-anti-seepage yefilimu yepulasitiki. Amafilimu epulasitiki asetshenziselwa izinhlelo zokulwa nokungaboni ngaso linye ngaphakathi nakwamanye amazwe ikakhulukazi afaka i-(PVC) i-polyethylene (PE) ne-ethylene/vinyl acetate copolymer (EVA). Ziwuhlobo lwezinto eziguquguqukayo zamakhemikhali e-polymer ezine-gravity ethize ethile, ukunwebeka okuqinile, ukuguquguquka okuphezulu kokuguquguquka, ukumelana nokugqwala, ukumelana nezinga lokushisa eliphansi, nokumelana nesithwathwa okuhle. Impilo yesevisi yama-geomembranes ayinhlanganisela inqunywa ngokuyinhloko ukuthi ingabe ifilimu yepulasitiki ilahlekelwa yizindawo zayo zokunqanda ukugeleza nokungangeni kwamanzi. Ngokwezindinganiso zikazwelonke zaseSoviet, amafilimu e-polyethylene anobukhulu obungu-0.2m kanye nezinzile ezisetshenziselwa ubunjiniyela bamanzi angasebenza 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.
