I-Geomembrane yinto engenamanzi kunye nesithintelo esisekwe kwizinto eziphezulu zepolymer. Ikakhulu yohlulwe kwi-polyethylene ephantsi (LDPE) geomembrane, i-polyethylene ephezulu (HDPE) geomembrane, kunye ne-EVA geomembrane. I-warp knitted composite geomembrane yahlukile kwi-geomembranes jikelele. Uphawu lwayo kukuba ukudibana kobude kunye nobubanzi abugobekanga, kwaye nganye ikwimo ethe tye. Bopha ezi zibini ngokuqinileyo ngentambo ephothiweyo, enokuthi ihambelane ngokulinganayo, imelane nemikhosi yangaphandle, isasaze uxinzelelo, kwaye xa amandla angaphandle asetyenziswayo akrazula izinto eziphathekayo, umsonto uya kuhlanganisana kunye nokuqhekeka kokuqala, ukwandisa ukuxhathisa ukukrazula. Xa kusetyenziswa i-warp enithiweyo edityanisiweyo, intambo elukiweyo ye-warp iphinda-phinda ithandelwe phakathi kwe-fiber layers ye-warp, weft, kunye ne-geotextile ukuluka ezi zintathu zibe yinto enye. Ke ngoko, i-warp knitted composite geomembrane ineempawu zokuqina okuphezulu kunye nobude obuphantsi, kunye nokusebenza kokungangeni kwamanzi kwe-geomembrane. Ke ngoko, i-warp knitted composite geomembrane luhlobo lwezinto ezichasene ne-seepage ezinemisebenzi yokomeleza, ukwahlula kunye nokukhusela. Sisicelo esikwinqanaba eliphezulu lemathiriyeli edityanisiweyo ye-geosynthetic kumazwe ngamazwe namhlanje.

Amandla okuqina aphezulu, ubude obuphantsi, i-deformation efanayo kunye ne-deformation eguquguqukayo, ukuxhathisa ukukrazula, ukuxhathisa okugqwesileyo, kunye nokumelana okunamandla kwamanzi. ilaphu elilukiweyo. Ukusebenza kwayo okuchasene ne-seepage ikakhulu kuxhomekeke ekusebenzeni kwe-anti-seepage yefilimu yeplastiki. Iifilimu zeplastiki ezisetyenziselwa ukusetyenziswa kwe-anti-seepage ekhaya nakwamanye amazwe ikakhulukazi ziquka (PVC) i-polyethylene (PE) kunye ne-ethylene / vinyl acetate copolymer (EVA). Zizinto eziguquguqukayo zeekhemikhali ze-polymer ezinomxhuzulane okhethekileyo, ukolula olomeleleyo, ukuguquguquka okuphezulu kwi-deformation, ukuxhathisa kwi-corrosion, ukumelana nobushushu obuphantsi, kunye nokuxhathisa okuhle kweqabaka. Ubomi benkonzo yefilimu ye-geotextile edibeneyo inqunywe ngokukodwa ukuba ifilimu yeplastiki ilahlekelwe yi-anti-seepage kunye nomsebenzi wokuthintela amanzi. Ngokwemigangatho kazwelonke yeSoviet Union, ifilimu ye-polyethylene enobunzima be-0.2m kunye ne-stabilizer esetyenziselwa ubunjineli be-hydraulic inokusebenza 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.
