Geomembrane mejupụtara bụ ihe geotextile mgbochi seepage nke ihe nkiri rọba mejupụtara dị ka mkpụrụ mgbochi seepage na akwa anaghị kpara akpa. 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 polyvinyl chloride (PVC), polyethylene (PE), na ethylene/vinyl acetate copolymer (EVA).
