Igice cyo hejuru cyigipfundikizo cyamazi kitagira amazi ni firime yuzuye ya polyethylene (HDPE) kandi igice cyo hasi nigitambara kidoda. Sodium bentonite yipfundikiriye amazi adafite amazi meza ashyirwa hagati ya geotextile ifite imbaraga nyinshi ukoresheje uburyo bwihariye bwo gukubita inshinge hanyuma ugashyirwa kumyenda idoda. Igice cya firime yuzuye ya polyethylene (HDPE) irubahirizwa. Igipangu kitagira amazi ya Bentonite gifite imbaraga zidafite amazi kandi zirwanya seepage kuruta igipangu gisanzwe cya bentonite. Uburyo bwo kwirinda amazi ni uko uduce twa bentonite twaguka iyo duhuye n’amazi, tugakora sisitemu imwe. Mugihe cyo kubuza ibice bibiri bya geotextile, bentonite yaguka kuva mukaduruvayo. Igisubizo cyo gukomeza kwinjiza amazi no kwaguka ni ugukora bentonite ubwayo. , bityo bikagira ingaruka zidafite amazi.
Ibiranga umubiri biranga igipangu kitagira amazi:
. Bentonite ni ibintu bisanzwe bidakoreshwa muburyo bwo gusaza kandi bifite igihe kirekire; kandi ntabwo bizagira ingaruka mbi kubidukikije nibikoresho byangiza ibidukikije
2. Ifite ibintu byose biranga ibikoresho bya geotextile, nko gutandukana, gushimangira, kurinda, kuyungurura, nibindi biroroshye kubaka kandi ntibibujijwe nubushyuhe bwibidukikije byubaka. Irashobora kandi kubakwa munsi ya 0 ℃. Mugihe cyo kubaka, ukeneye gusa gushyira GCL igipangu kitarimo amazi. Mugihe wubaka kuruhande cyangwa ahahanamye, bikosore imisumari nogeshe, hanyuma ubirengere nkuko bisabwa.
3. Biroroshye gusana; na nyuma yo kubaka amazi (seepage) yarangiye, niba igice cyangiza amazi cyangiritse kubwimpanuka, mugihe igice cyangiritse gisanwe gusa, imikorere idahwitse irashobora kugarurwa.
4. Igipimo cyibikorwa-igiciro kiri hejuru cyane kandi gifite uburyo bwinshi bwo gukoresha.
5. Ubugari bwibicuruzwa bushobora kugera kuri metero 6, bujyanye n’ibisobanuro mpuzamahanga bya geotextile (membrane), bikazamura cyane ubwubatsi.
6. Birakwiriye kuvura anti-seepage no gutemba ahantu hashobora gukenerwa cyane no kwirinda amazi, nka tunel, metero, munsi yo munsi, inzira zo munsi y'ubutaka, inyubako zitandukanye zo munsi y'ubutaka hamwe n'imishinga y'amazi afite ubutunzi bukomeye bw'amazi yo mu butaka.
