Geomembrane ke thepa e thibelang metsi le e thibelang metsi e thehiloeng ho li-polymers tse phahameng tsa boima ba limolek'hule. Haholo-holo e arotsoe ka polyethylene (LDPE) geomembranes ea "low-density polyethylene", "high-density polyethylene (HDPE) geomembranes, le EVA geomembranes. Geomembrane e entsoeng ka knitted e fapane le li-geomembrane tse akaretsang. Sebopeho sa eona ke hore mateano a mela ea longitude le latitude ha a kobehe, 'me e' ngoe le e 'ngoe e maemong a otlolohileng. Ho sebelisa khoele e lohiloeng ho tlama ka tieo tse peli ho ka finyella ho lumellana ha mokhoa o ts'oanang, ho mamella matla a ka ntle, ho aba khatello ea kelello, 'me ha matla a ka ntle a sebelisoa a rusolla thepa, khoele e tla bokana hammoho le petso ea pele, e eketsa ho hanyetsa meokho. Nakong ea ho loha ha motsoako oa warp, khoele e lohang e fetisetsoa khafetsa pakeng tsa likaroloana tsa warp, weft le fiber tsa geomembrane ho loha tse tharo hore e be ntho e le 'ngoe. Ka hona, li-geomembrane tse lohiloeng tse lohiloeng ha li na feela litšobotsi tsa matla a phahameng a tsitsipano le bolelele bo tlase, empa hape li na le ts'ebetso e sa keneleng metsi ea li-geomembrane. Ka hona, warp knitted composite geomembrane ke thepa e khahlanong le seepage e nang le mesebetsi ea ho matlafatsa, ho itšehla thajana le ho sireletsa. Ke ts'ebeliso e tsoetseng pele haholo ea lisebelisoa tse kopaneng tsa geosynthetic machabeng kajeno.

Matla a phahameng a tsitsitseng, bolelele bo tlaase, ho fetoha ha mokhoa o ts'oanang oa longitudinal le transverse, khanyetso e phahameng ea ho taboha, ho hanyetsa ho apara hantle, le ho thibela metsi a matla. lesela. Ts'ebetso ea eona e khahlanong le seepage haholo-holo e itšetlehile ka ts'ebetso e khahlanong le seepage ea filimi ea polasetiki. Lifilimi tsa polasetiki tse sebelisetsoang li-anti-seepage applications ka hare ho naha le linaheng tse ling haholo-holo li kenyelletsa (PVC) polyethylene (PE) le ethylene / vinyl acetate copolymer (EVA). Ke mofuta oa lintho tse feto-fetohang tsa lik'hemik'hale tsa polymer tse nang le khoheli e nyane e ikhethang, katoloso e matla, ho ikamahanya le maemo ho hoholo, ho hanyetsa kutu, ho hanyetsa mocheso o tlase, le ho hanyetsa serame hantle. Bophelo ba ts'ebeletso ea li-geomembranes tse kopantsoeng bo khethoa haholo-holo ke hore na filimi ea polasetiki e lahleheloa ke thepa ea eona e thibelang metsi le e thibelang metsi. Ho ea ka litekanyetso tsa naha ea Soviet Union, lifilimi tsa polyethylene tse nang le botenya ba 0.2m le li-stabilizer tse sebelisoang boenjiniere ba metsi li ka sebetsa lilemo tse 40-50 tlas'a maemo a metsi a hlakileng le lilemo tse 30-40 tlas'a maemo a likhoerekhoere. Ka hona, bophelo ba tšebeletso ea motsoako oa geomembrane bo lekane ho finyella litlhoko tse khahlanong le seepage tsa letamo.
