Geombranendi zinthu zopanda madzi komanso zotchinga zochokera ku polima wapamwamba.Amagawidwa kukhala otsika kachulukidwe polyethylene (LDPE) geomembranes, mkulu kachulukidwe polyethylene(HDPE) geomembranes, ndi EVA geomembranes.Geomembrane yopangidwa ndi Warp ndi yosiyana ndi geomembrane wamba.Khalidwe lake ndilakuti mphambano ya longitude ndi latitude sinapindikidwe, ndipo chilichonse chimakhala chowongoka.Mangani awiriwo mwamphamvu ndi waya woluka, womwe ukhoza kugwirizanitsidwa mofanana, kupirira mphamvu zakunja, kugawanitsa nkhawa, ndipo pamene mphamvu yakunja yogwiritsidwa ntchito ikung'amba zakuthupi, ulusi udzasonkhanitsa pamodzi ndi mng'alu woyamba, ndikuwonjezera kukana misozi.Ulusi wolukidwa wa warp ukagwiritsidwa ntchito, ulusi wolukidwa wa warp umangirizidwa mobwerezabwereza pakati pa zigawo za warp, weft, ndi geotextile, kumapanga zitatuzo kukhala imodzi.Choncho, warp knitted gulu geomembrane osati ndi makhalidwe a mkulu kumakoka mphamvu ndi otsika elongation, komanso ali ndi ntchito madzi geomembrane.Choncho, warp knitted composite geomembrane ndi mtundu wa zinthu zotsutsana ndi seepage zomwe zimakhala ndi ntchito zolimbitsa, kudzipatula, ndi chitetezo.Ndizinthu zapamwamba zogwiritsidwa ntchito za geosynthetic padziko lonse lapansi masiku ano.

Kuthamanga kwakukulu, kutalika kochepa, kusinthasintha kwautali komanso kusinthika kosinthika, kukana misozi, kukana kuvala bwino, komanso kukana madzi mwamphamvu.Kuchita kwake kotsutsa-seepage makamaka kumadalira filimu yotsutsa-seepage ya filimu yapulasitiki.Makanema apulasitiki omwe amagwiritsidwa ntchito popewa kuti asalowe kunyumba ndi kunja makamaka amaphatikiza (PVC) polyethylene (PE) ndi ethylene/vinyl acetate.copolymer (EVA), zomwe ndi zida zosinthika za chemistry ya Polymer yokhala ndi mphamvu yokoka yaying'ono, kufalikira kwamphamvu, kusinthasintha kwakukulu kwa mapindikidwe, kukana kwa dzimbiri, kukana kutentha pang'ono komanso kukana chisanu.Moyo wautumiki wa gulu la geomembrane umatsimikiziridwa makamaka ngati filimu ya pulasitiki yataya ntchito yake yotsutsa-seepage ndi kulekanitsa madzi.Malinga ndi mfundo za 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 omveka bwino komanso zaka 30-40 pansi pa zimbudzi.Choncho, moyo wautumiki wa geomembrane wophatikizika ndi wokwanira kukwaniritsa zofunikira zotsutsana ndi madzi a damu.
