I-Geombraneiyinto engangeni manzi futhi iyisithiyo esekelwe ku-polymer ephezulu.Ihlukaniswe kakhulu i-low density polyethylene (LDPE) geomembranes, i-polyethylene ephezulu kakhulu(HDPE) ama-geomembranes, kanye ne-EVA geomembranes.I-Warp knitted composite geomembrane yehlukile ku-geomembrane evamile.Isici sayo siwukuthi ukuphambana kwe-longitude ne-latitude akugobile, futhi ngayinye isesimweni esiqondile.Hlanganisa lezi zinto ezimbili ngokuqinile ngocingo olulukiwe, olungavunyelaniswa ngokulinganayo, lumelane namandla angaphandle, ukusabalalisa ukucindezeleka, futhi lapho amandla angaphandle asetshenziswayo edabula impahla, intambo izoqoqana eduze nokuqhekeka kokuqala, okwandisa ukumelana nezinyembezi.Uma kusetshenziswa inhlanganisela elukiwe ye-warp elukiweyo, izintambo eziluka ezisontekile zilukwa ngokuphindaphindiwe phakathi kwezingqimba zefiber ye-warp, weft, ne-geotextile, okwenza ezintathu ziphonswe zibe yinto eyodwa.Ngakho-ke, i-warp knitted composite geomembrane ayigcini nje ngokuba nezici zamandla aqinile aphezulu kanye nobude obuphansi, kodwa futhi inokusebenza okungangeni kwamanzi kwe-geomembrane.Ngakho-ke, i-warp knitted composite geomembrane iwuhlobo lwento emelene ne-seepage enemisebenzi yokuqinisa, ukuhlukanisa, nokuvikela.Kuyinto esezingeni eliphezulu esetshenziswayo ye-geosynthetic emphakathini wamazwe ngamazwe namuhla.

Amandla aqinile aphezulu, ubude obuphansi, ukuguquguquka okufanayo kwe-longitudinal kanye ne-transverse, ukumelana nokukhala okukhulu, ukumelana okuhle kakhulu kokugqokwa, nokumelana namanzi okuqinile.Ukusebenza kwayo kwe-anti-seepage ikakhulukazi kuncike ekusebenzeni kwe-anti-seepage yefilimu yepulasitiki.Amafilimu epulasitiki asetshenziselwa ukuvimbela ukuphuma kwamanzi ekhaya nakwamanye amazwe ikakhulukazi ahlanganisa (PVC) i-polyethylene (PE) ne-ethylene/vinyl acetate.i-copolymer (EVA), okuyizinto eziguquguqukayo ze-Polymer chemistry enamandla amancane adonsela phansi, ukunwebeka okuqinile, ukuguquguquka okuphezulu kokuguquguquka, ukumelana nokugqwala, ukumelana nokushisa okuphansi kanye nokumelana nesithwathwa okuhle.Impilo yesevisi ye-geomembrane eyinhlanganisela inqunywa ngokuyinhloko ukuthi ingabe ifilimu yepulasitiki ilahlekelwe yini umsebenzi wayo wokunqanda ukuphuma nokuhlukaniswa kwamanzi.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.
