Composite geomembrane ke thepa e khahlanong le seepage ea geotextile e entsoeng ka filimi ea polasetiki e le substrate e khahlanong le seepage le lesela le sa 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 ka hare ho naha le linaheng tse ling haholo-holo li kenyelletsa polyvinyl chloride (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 matla a khoheli a tlase, ho atolosoa ho 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.

1. Ho kopanya mesebetsi e thibelang metsi le ho ntša metsi, ha e ntse e e-na le mesebetsi e kang ho itšehla thajana le ho matlafatsa.
2. Matla a kopantsoeng a phahameng, matla a lekhapetla le phahameng, le ho hanyetsa ho phunya ho phahameng.
3. Bokhoni bo matla ba drainage, coefficient e phahameng ea likhohlano, le coefficient e tlase ea mela.
