Polyethylene geomembrane nke nwere njupụta dị elu bụ ihe a na-ejikarị eme ihe na-egbochi ịkwọ ụgbọ mmiri n'ime ebe a na-ekpofu ahịhịa.HDPE Geomembrane pụtara n'etiti ngwaahịa polyethylene nke nwere ike ya dị elu, akụrụngwa kemịkalụ kwụsiri ike, yana arụmọrụ mgbochi ịka nká nke ukwuu, ndị na-emepụta na ndị nwe ụlọ ọrụ na-ekpofu ahịhịa jikwa ya kpọrọ ihe nke ukwuu.
Ngwunye ala na-agụnyekarị nsogbu nke leachate nwere ihe ndị na-egbu egbu na ndị na-emerụ ahụ, kemịkalụ dị ize ndụ, na nsogbu ndị ọzọ.Ihe eji eme injinia nwere ọnọdụ ojiji dị oke mgbagwoju anya, gụnyere ihe ike, ọnọdụ okike, mgbasa ozi, oge, wdg, yana ihe dị iche iche etinyere.Ogo nke mmetụta mgbochi-seepage na-ekpebi kpọmkwem ogo injinia, na ndụ ọrụ nke geomembrane bụkwa isi ihe na-ekpebi ndụ injinia.Ya mere, ihe mgbochi na-ahụ maka ihe ndị a na-eji eme ihe na-ekpuchi ala ga-enwerịrị ezigbo ọrụ mgbochi anya, ezigbo biodegradability, na arụmọrụ antioxidation dị mma, n'etiti ihe ndị ọzọ.
Mgbe ọtụtụ afọ nke nyocha na omume na ụlọ ọrụ nyocha geomembrane nke ụlọ ọrụ anyị, geomembrane nke a na-eji na sistemụ mgbochi seepage maka ebe a na-ekpofu ahịhịa agaghị abụ naanị ịgbaso ụkpụrụ teknụzụ mba na nke mba dị ugbu a kamakwa ọ ga-emezu ihe ndị a:
