ʻO Geomembrane kahi mea wai a me ka pale e pili ana i nā mea polymer kiʻekiʻe. Hoʻokaʻawale ʻia ʻo ia i ka polyethylene haʻahaʻa haʻahaʻa (LDPE) geomembrane, kiʻekiʻe-density polyethylene (HDPE) geomembrane, a me EVA geomembrane. He ʻokoʻa ka geomembrane i hui pū ʻia me ka geomembrane maʻamau. ʻO kona ʻano, ʻaʻole i ʻope ka hui ʻana o ka longitude a me ka latitu, a aia kēlā me kēia ma ke ʻano pololei. E hoʻopaʻa paʻa i nā mea ʻelua me ke kaula wili, hiki ke hoʻonohonoho like ʻia, kū i nā ikaika o waho, puʻunaue i ke koʻikoʻi, a i ka wā e haehae ai ka ikaika o waho i ka mea, e hōʻuluʻulu ka ʻili ma ka māwae mua, e hoʻonui ai i ke kūpaʻa waimaka. Ke hoʻohana ʻia ka hui wili ʻia, hoʻopaʻa pinepine ʻia ka milo i ulana ʻia ma waena o nā papa fiber o ka warp, weft, a me ka geotextile e ulana i nā ʻekolu i hoʻokahi. No laila, ʻo ka warp knitted composite geomembrane nā hiʻohiʻona o ka ikaika tensile kiʻekiʻe a me ka elongation haʻahaʻa, a me ka hana wai ʻole o ka geomembrane. No laila, ʻo ka geomembrane i hoʻopili ʻia he ʻano mea anti-seepage i loaʻa nā hana o ka hoʻoikaika, kaʻawale, a me ka pale. He noi kiʻekiʻe ia o nā mea hoʻohui honua geosynthetic i kēia lā.

ʻO ka ikaika tensile kiʻekiʻe, ka elongation haʻahaʻa, ka lōʻihi lōʻihi a me ka transverse deformation, ke kūpaʻa waimaka kiʻekiʻe, ke kūpaʻa maikaʻi loa, a me ke kūpaʻa wai ikaika. lole ulana. ʻO kāna hana anti-seepage ma muli o ka hana anti-seepage o ke kiʻiʻoniʻoni plastik. ʻO nā kiʻiʻoniʻoni plastik i hoʻohana ʻia no nā noi anti-seepage ma ka home a me nā ʻāina ʻē aʻe ka nui o (PVC) polyethylene (PE) a me ka ethylene/vinyl acetate copolymer (EVA). He mau mea maʻalahi kemika polymer me ka umekaumaha kikoʻī liʻiliʻi, ka hoʻonui ikaika, ka hiki ke hoʻololi i ka deformation, ka pale ʻana i ka corrosion, ka haʻahaʻa haʻahaʻa haʻahaʻa, a me ka pale hau maikaʻi. Hoʻoholo nui ʻia ke ola lawelawe o ke kiʻi geotextile composite inā ua nalowale ke kiʻi ʻoniʻoni i kāna hana anti-seepage a me ka pale wai. Wahi a nā kūlana aupuni o ka Soviet Union, hiki i ka polyethylene film me ka mānoanoa o 0.2m a me kahi stabilizer i hoʻohana ʻia i ka ʻenekini hydraulic hiki ke hana no 40-50 mau makahiki ma lalo o nā kūlana wai maʻemaʻe a me 30-40 mau makahiki ma lalo o nā kūlana wai. No laila, lawa ke ola lawelawe o ka geomembrane composite e hoʻokō i nā koi anti-seepage o ka dam.
