IGeombranesisixhobo esingenamanzi kunye nesithintelo esisekwe kwipolymer ephezulu.Ukwahlulwe kakhulu kwi-polyethylene yoxinaniso oluphantsi (LDPE) geomembranes, ipolyethylene yoxinaniso oluphezulu(HDPE) geomembranes, kunye ne-EVA geomembranes.I-Warp knitted composite geomembrane yahlukile kwi-geomembrane jikelele.Uphawu lwayo kukuba ukudibana kobude kunye nobubanzi abugobekanga, kwaye nganye ikwimo ethe tye.Zibophe ezi zimbini ngokuqinileyo ngocingo oluphothiweyo, ezinokulungelelaniswa ngokulinganayo, ukumelana namandla angaphandle, ukusabalalisa uxinzelelo, kwaye xa amandla angaphandle asetyenziswayo akrazula izinto, umsonto uya kuhlanganisana kunye nokuqhekeka kokuqala, ukwandisa ukuxhathisa ukukrazula.Xa kusetyenziswa i-warp enithiweyo edityanisiweyo, imisonto elukiweyo iye yaphinda yaphonswa phakathi kolwaleko lwefayibha ye-warp, i-weft, kunye ne-geotextile, nto leyo eyenza ezi zintathu zithungwe zibe yinto enye.Ke ngoko, i-warp knitted composite geomembrane ayinayo kuphela iimpawu zokuqina okuphezulu kunye nobude obuphantsi, kodwa inokusebenza kokungangeni kwamanzi kwe-geomembrane.Ke ngoko, i-warp knitted composite geomembrane luhlobo lwezinto ezichasene ne-seepage ezinemisebenzi yokomeleza, ukwahlula kunye nokukhusela.Yimathiriyeli ye-geosynthetic ekwinqanaba eliphezulu kuluntu lwehlabathi namhlanje.
Amandla aphezulu, ubude obuphantsi, i-unitudinal longitudinal kunye ne-deformation eguquguqukayo, ukuxhathisa ukukrazula, ukuxhathisa okugqwesileyo, kunye nokuxhathisa okunamandla kwamanzi.Ukusebenza kwayo kwe-anti-seepage ikakhulu kuxhomekeke ekusebenzeni kwe-anti-seepage yefilimu yeplastiki.Iifilimu zeplastiki ezisetyenziselwa ukuthintela ukungcola ekhaya nakwamanye amazwe ikakhulu zibandakanya (PVC) i-polyethylene (PE) kunye ne-ethylene / vinyl acetatei-copolymer (EVA), ezizizixhobo eziguquguqukayo ze-Polymer chemistry ezinobunzima obuthile obuncinci, ukwanda okunamandla, ukuguquguquka okuphezulu kwi-deformation, ukumelana nokugqwala, ukumelana nobushushu obuphantsi kunye nokuxhathisa okulungileyo kweqabaka.Ubomi benkonzo ye-geomembrane edibeneyo inqunywe ngokukodwa ukuba ifilimu yeplastiki ilahlekelwe ngumsebenzi wayo wokulwa nokwahlukana kwamanzi.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.
