Geomembrane ke thepa e sa keneleng metsi le e thibelang metsi e thehiloeng ho thepa e phahameng ea polymer. E arotsoe haholo-holo ka polyethylene e tlaase-tlaase (LDPE) geomembrane, polyethylene e phahameng haholo (HDPE) geomembrane, le EVA geomembrane. The warp knitted composite geomembrane e fapane le li-geomembrane tse akaretsang. Sebopeho sa eona ke hore mateano a litsela tsa longitude le latitude ha a kobehe, 'me e' ngoe le e 'ngoe e boemong bo otlolohileng. Tlama tse peli ka thata ka khoele e lohiloeng, e ka kopanngoang ka mokhoa o ts'oanang, e mamella matla a ka ntle, e aba khatello ea kelello, 'me ha matla a ka ntle a sebelisoang a tabola thepa, khoele e tla bokella hammoho le petso ea pele, e eketsa ho hanyetsa ho tabola. Ha ho sebelisoa motsoako o lohiloeng oa warp, khoele e lohiloeng ea warp e etsoa khafetsa lipakeng tsa likhoele tsa warp, weft, le geotextile ho loha tse tharo ho ba ntho e le 'ngoe. Ka hona, warp knitted composite geomembrane e na le litšobotsi tsa matla a phahameng a tsitsipano le bolelele bo tlaase, hammoho le ts'ebetso e sa keneleng metsi ea geomembrane. Ka hona, warp knitted composite geomembrane ke mofuta oa thepa e khahlanong le seepage e nang le mesebetsi ea ho matlafatsa, ho itšehla thajana le ho sireletsa. Ke ts'ebeliso ea maemo a holimo 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 se mamelle ha metsi, le ho thibela metsi a matla. lesela le lohiloeng. 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 lapeng le kantle ho naha li kenyelletsa (PVC) polyethylene (PE) le ethylene / vinyl acetate copolymer (EVA). Ke lisebelisoa tse feto-fetohang tsa lik'hemik'hale tsa polymer tse nang le matla a khoheli a manyane, katoloso e matla, ho ikamahanya le maemo ho hoholo, ho hanyetsa kutu, ho hanyetsa mocheso o tlase, le ho hanyetsa serame hantle. Bophelo ba tšebeletso ea filimi ea geotextile e kopantsoeng haholo-holo bo khethoa ke hore na filimi ea polasetiki e lahlehetsoe ke mosebetsi oa eona oa ho thibela metsi le ho thibela metsi. Ho ea ka litekanyetso tsa naha tsa Soviet Union, filimi ea polyethylene e nang le botenya ba 0.2m le stabilizer e sebelisoang ka boenjiniere ba hydraulic e 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.
