I-Geomembrane yinto engenamanzi kunye nesithintelo esisekwe kwiipolymers ezinobunzima bemolekyuli. Ikakhulu yohlulwe ibe yi-polyethylene ephantsi (LDPE) geomembranes, i-polyethylene ephezulu (HDPE) geomembranes, kunye ne-EVA geomembranes. I-geomembrane ehlanganisiweyo ehlanganisiweyo yahlukile kwi-geomembranes jikelele. Uphawu lwayo kukuba ukuhlangana kwemigca yobude kunye nelathithudi ayigobekanga, kwaye nganye ikwimo ethe tye. Ukusebenzisa intambo ephothiweyo ukubopha ngokuqinileyo ezi zibini zinokufezekisa ukuvumelanisa okufanayo, ukumelana nemikhosi yangaphandle, ukusabalalisa uxinzelelo, kwaye xa amandla angaphandle asetyenziswayo akrazula izinto eziphathekayo, umsonto uya kuhlanganisana kunye nokuqhekeka kokuqala, ukwandisa ukuxhathisa ukukrazula. Ngexesha le-warp knitting composite, intambo yokunitha ye-warp igqithiswa ngokuphindaphindiweyo phakathi kwe-warp, i-weft, kunye ne-fiber layers ye-geomembrane ukuluka ezintathu zibe yinto enye. Ke ngoko, ii-geomembranes ezidityanisiweyo ze-warp ezinithiweyo azinayo nje impawu zamandla okuqina aphezulu kunye nobude obuphantsi, kodwa zikwanentsebenzo yokungangeni kwamanzi kwee-geomembranes. Ke ngoko, i-warp knitted composite geomembrane yimathiriyeli echasene ne-seepage enemisebenzi yokuqinisa, yodwa kunye nokukhusela. Sisicelo esiphezulu kakhulu semathiriyeli edityanisiweyo ye-geosynthetic kumazwe ngamazwe namhlanje.

Amandla aphezulu, ubude obuphantsi, i-unitudinal longitudinal kunye ne-deformation eguquguqukayo, ukuxhathisa ukukrazula, ukuxhathisa okugqwesileyo, kunye nokumelana okunamandla kwamanzi. ilaphu. Ukusebenza kwayo okuchasene ne-seepage ikakhulu kuxhomekeke ekusebenzeni kwe-anti-seepage yefilimu yeplastiki. Iifilimu zeplastiki ezisetyenziselwa ukusetyenziswa kwe-anti-seepage izicelo zangaphakathi kunye nakwamanye amazwe ngokubanzi ziquka (PVC) i-polyethylene (PE) kunye ne-ethylene / vinyl acetate copolymer (EVA). Zizintlobo zezinto eziguquguqukayo zeekhemikhali zepolymer ezinobunzima obuthile obuncinci, ukolula olomeleleyo, ukuguquguquka okuphezulu kwi-deformation, ukumelana nokugqwala, ukumelana nobushushu obuphantsi, kunye nokuxhathisa okuhle kweqabaka. Ubomi benkonzo ye-geomembranes edibeneyo inqunywe ngokukodwa ukuba ifilimu yeplastiki ilahlekelwa yi-anti-seepage kunye neendawo ezichasene namanzi. Ngokwemigangatho yelizwe laseSoviet, iifilimu ze-polyethylene ezinobunzima be-0.2m kunye nezizinzi ezisetyenziselwa ubunjineli bamanzi zingasebenza iminyaka engama-40-50 phantsi kweemeko zamanzi acacileyo kunye neminyaka engama-30-40 phantsi kweemeko zamanzi amdaka. Ngoko ke, ubomi benkonzo ye-geomembrane edibeneyo yanele ukuhlangabezana neemfuno ezichasene ne-seepage zedama.
