Geomembranehe mea wai a me ka mea pale ma muli o ka polymer kiʻekiʻe.Hoʻokaʻawale nui ʻia i nā geomembranes haʻahaʻa haʻahaʻa polyethylene (LDPE), polyethylene kiʻekiʻe.(HDPE) geomembranes, a me nā geomembranes EVA.He ʻokoʻa ka geomembrane i hui ʻia me ka geomembrane maʻamau.ʻO kona hiʻohiʻona, ʻaʻole i ʻāwili ʻia 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 ka uwea wili, hiki ke hoʻonohonoho like ʻia, kū i nā ikaika o waho, e puʻunaue i ke koʻikoʻi, a i ka wā e haʻihaʻi ai ka ikaika o waho i ka mea, e hōʻiliʻili ka wili ma ka māwae mua, e hoʻonui ai i ka waimaka.I ka hoʻohana ʻia ʻana o ka hui wili liʻiliʻi, hoʻopaʻa pinepine ʻia nā kaula wili ma waena o nā papa fiber o warp, weft, a me geotextile, e hui pū ʻia nā ʻekolu i hoʻokahi.No laila, ʻaʻole wale nā ​​hiʻohiʻona o ka ikaika tensile kiʻekiʻe a me ka elongation haʻahaʻa, akā loaʻa pū kekahi i ka hana wai o 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 kiʻekiʻe kiʻekiʻe i hoʻohana ʻia i nā mea geosynthetic i ke kaiāulu honua i kēia lā.

ʻO ka ikaika tensile kiʻekiʻe, ka elongation haʻahaʻa, ka lōʻihi lōʻihi a me ka deformation transverse, ke kūpaʻa waimaka kiʻekiʻe, ke kūpaʻa maikaʻi loa, a me ke kūpaʻa wai ikaika.ʻO kāna hana anti-seepage e hilinaʻi nui ʻia i ka hana anti-seepage o ka kiʻiʻoniʻoni plastik.ʻO nā kiʻiʻoniʻoni plastik i hoʻohana ʻia no ka pale ʻana i ka seepage ma ka home a me nā ʻāina ʻē he nui (PVC) polyethylene (PE) a me ka ethylene/vinyl acetate.copolymer (EVA), He mau mea maʻalahi o ka kemika Polymer me ka umekaumaha kikoʻī liʻiliʻi, ka hoʻonui ikaika, ke kiʻekiʻe adaptability i ka deformation, ka pale ʻana i ka corrosion, ka haʻahaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa hau maikaʻi.Hoʻoholo nui ʻia ke ola lawelawe o ka geomembrane composite inā ua nalowale ke kiʻi ʻoniʻoni i kāna hana anti-seepage a me ka hoʻokaʻawale 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 a hiki i 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.
