Kubva kuma1950, mainjiniya akabudirira kugadzira nema geomembranes.Kushandiswa kwegeomembranes, inonziwo flexible membrane liners (FMLs), kwawedzera nekuda kwekunetseka kuri kukura pamusoro pekusvibiswa kwemvura yakakosha.Traditional porous liners, senge kongiri, admix zvinhu, ivhu uye ivhu zvakaratidza kusahadzika mukudzivirira kwemvura inofamba ichienda kune pasi pevhu uye pasi pevhu.Sezvineiwo, seepage kuburikidza neasiri porous marudzi emagetsi, anoti geomembranes, anga ari mazita.Muchokwadi, kana ichiedzwa nenzira yakafanana nevhu, kupenya kwemvura kuburikidza neyakagadzirwa geomembrane kwave kusingayereki.Zvinodiwa zvekuisa zvinosarudza rudzi rwe geomembrane.Geomembranes inowanika mumhando dzakasiyana-siyana dzemuviri, mechanical uye makemikari ekupikisa zvivakwa zvakagadzirirwa kusangana nezvinodiwa zvehuwandu hwemashandisirwo.Zvigadzirwa zvinogona kusanganiswa kuti zvionekwe kune ultraviolet mwenje, ozone uye tupukanana muvhu.Musanganiswa wakasiyana weizvi zvivakwa uripo mune akasiyana geosynthetic lining zvinhu kuvhara yakafara spectrum ye geotechnical application uye dhizaini.Nzira dzinoverengeka dzinoshandiswa kujoina geosynthetic lining zvinhu mufekitori uye mumunda.Chinyorwa chega chega chine hunyanzvi hwekudzora hunhu hunotonga kugadzirwa kwayo nekuiswa kwayo.Zvigadzirwa zvitsva uye nzira dzakavandudzwa dzekugadzira nekuisa dzinoramba dzichigadzirwa sezvo indasitiri inovandudza tekinoroji yayo.Daelim, anozivikanwa semutungamiri pakati pemakambani epetrochemical muKorea ane ma naptha crackers uye ane hukama pasi pemvura resin zvirimwa, ane hurefu hwepagore hunosvika 7,200 matani eHDPE Geomembrane nehukobvu hunotangira pa 1 kusvika 2.5 mm uye nehupamhi hwepamusoro hwe6.5 m.Daelim Geomembranes inogadzirwa neiyo flat-die extrusion nzira pasi pekusimba kwehutongi hwemhando.Vashandi vemukati vehunyanzvi uye R&D centre vakapa Daelim iyo yakasarudzika kugona kupa vatengi mhando dzakasiyana dzehunyanzvi data izvo zvakakosha pakugadzira ruzha uye kuisa geomembranes.
