Geomembrane bụ ihe mgbochi mmiri na ihe mgbochi dabere na polymer arọ molekụla dị elu. A na-ekewa ya na polyethylene dị ala (LDPE) geomembranes, polyethylene dị elu (HDPE) geomembranes, na EVA geomembranes. Geomembrane jikọtara ọnụ dị iche na geomembrane izugbe. Ihe e ji mara ya bụ na njikọ nke ahịrị longitude na latitude adịghị agbagọ, na nke ọ bụla nọ n'ọnọdụ kwụ ọtọ. Iji eriri kpara akpa iji kechie ha abụọ nwere ike nweta mmekọrịta otu, nagide ike mpụga, kesaa nrụgide, na mgbe ike mpụga etinyere na-adọwa ihe ahụ, yarn ga-agbakọta n'akụkụ mgbape mbụ ahụ, na-abawanye nguzogide akwa mmiri. N'oge a na-akpakọta warp, a na-agafe eri warp ahụ ugboro ugboro n'etiti akwa warp, weft na fiber nke geomembrane iji kpaa atọ ahụ ka ọ bụrụ otu. Ya mere, geomembranes mejupụtara warp ọ bụghị naanị nwere njirimara nke ike tensile dị elu na elongation dị ala, kamakwa nwere arụmọrụ geomembranes na-egbochi mmiri. Ya mere, geomembrane nke a kpara akpa bụ ihe na-egbochi ịhụ ihu nke nwere ọrụ nkwado, ikewapụ na nchekwa. Ọ bụ ngwa dị elu nke ihe mejupụtara geosynthetic na mba ụwa taa.

Ike tensile dị elu, elongation dị ala, ịdị ogologo ogologo na nrụrụ transverse, nguzogide akwa akwa, nkwụsi ike dị oke mma, na nguzogide mmiri siri ike. akwa akwa. Ọrụ mgbochi-seepage ya dabere na arụmọrụ mgbochi seepage nke ihe nkiri plastik. Ihe nkiri rọba a na-eji maka ngwa mgbochi seepage ma n'ime ụlọ na nke mba ụwa gụnyere (PVC) polyethylene (PE) na ethylene/vinyl acetate copolymer (EVA). Ha bụ ụdị ihe eji eme ihe na-agbanwe agbanwe nke polymer nwere obere ike ndọda, ike ndọtị, nnukwu mgbanwe maka nrụrụ, nguzogide corrosion, nguzogide okpomọkụ dị ala, yana ezigbo ntu oyi. A na-ekpebi ndụ ọrụ nke geomembranes mejupụtara ma ọ bụrụ na ihe nkiri plastik na-efunahụ ihe mgbochi anya na mmiri na-egbochi mmiri. Dị ka ụkpụrụ mba Soviet si dị, ihe nkiri polyethylene na ọkpụrụkpụ nke 0.2m na stabilizers eji eme ihe na mmiri mmiri nwere ike ịrụ ọrụ maka afọ 40-50 n'okpuru ọnọdụ mmiri doro anya na afọ 30-40 n'okpuru ọnọdụ nsị. Ya mere, ndụ ọrụ nke geomembrane composite zuru ezu iji gboo ihe mgbochi-seepage chọrọ nke dam.
