Geomembrane ndi zinthu zopanda madzi komanso zotchinga zochokera kuzinthu zapamwamba za polima. Amagawidwa makamaka mu polyethylene yotsika kwambiri (LDPE) geomembrane, polyethylene yapamwamba kwambiri (HDPE) geomembrane, ndi EVA geomembrane. The warp knitted composite geomembrane ndi yosiyana ndi geomembranes wamba. Khalidwe lake ndilakuti mphambano ya longitude ndi latitude sinapindikidwe, ndipo chilichonse chimakhala chowongoka. Mangani awiriwo mwamphamvu ndi ulusi wolukidwa, womwe ukhoza kugwirizanitsidwa mofanana, kupirira mphamvu zakunja, kugawaniza kupsinjika, ndipo pamene mphamvu yakunja yogwiritsidwa ntchito ikung'amba zakuthupi, ulusi udzasonkhanitsa pamodzi ndi mng'alu woyambirira, kuonjezera kukana misozi. Ulusi wolukidwa wa warp ukagwiritsidwa ntchito, ulusi wolukidwa wa warp umakulungidwa mobwerezabwereza pakati pa zigawo za warp, weft, ndi geotextile kuti aziluke zitatuzo kukhala chimodzi. Chifukwa chake, geomembrane yoluka yoluka ili ndi mawonekedwe amphamvu kwambiri komanso kutalika kocheperako, komanso magwiridwe antchito amadzi a geomembrane. Choncho, warp knitted composite geomembrane ndi mtundu wa zinthu zotsutsana ndi seepage zomwe zimakhala ndi ntchito zolimbitsa, kudzipatula, ndi chitetezo. Ndikugwiritsa ntchito kwapamwamba kwambiri kwa zida zamagulu a geosynthetic padziko lonse lapansi masiku ano.

Kulimba kwamphamvu kwambiri, kutalika kochepa, kupindika kofananako komanso kupindika, kung'ambika, kukana kuvala bwino, komanso kukana madzi mwamphamvu. nsalu nsalu. Kuchita kwake kotsutsa-seepage makamaka kumadalira machitidwe otsutsa a filimu yapulasitiki. Makanema apulasitiki omwe amagwiritsidwa ntchito polimbana ndi masamba kunyumba ndi kunja makamaka akuphatikizapo (PVC) polyethylene (PE) ndi ethylene/vinyl acetate copolymer (EVA). Ndizinthu zosinthika za polima zokhala ndi mphamvu yokoka yaying'ono, kukulitsa kwamphamvu, kusinthasintha kwakukulu kuti mapindike, kukana dzimbiri, kukana kutentha pang'ono, komanso kukana chisanu. Moyo wautumiki wa filimu yophatikizika ya geotextile imatsimikiziridwa makamaka ngati filimu ya pulasitiki yataya ntchito yake yotsutsana ndi seepage ndi kutsekereza madzi. Malinga ndi miyezo ya dziko la Soviet Union, filimu ya polyethylene yokhala ndi makulidwe a 0.2m ndi stabilizer yomwe imagwiritsidwa ntchito muukadaulo wama hydraulic imatha kugwira ntchito kwa zaka 40-50 pansi pamikhalidwe yamadzi oyera komanso zaka 30-40 pansi pa zimbudzi. Choncho, moyo wautumiki wa geomembrane wophatikizika ndi wokwanira kukwaniritsa zofunikira zotsutsana ndi madzi a damu.
