Gutema no gutwara: Ukurikije inyandiko zapimwe zubuso bwashyizwe hejuru, andika umubare wumubare munini wa geomembrane waciwe hanyuma ujyane aho washyizwe ukurikije umubare. Icyitonderwa, ntukurure cyangwa gukurura ingufu za geomembrane mugihe cyo gutwara kugirango wirinde ibintu bikarishye.

Kubaka no gushiraho geomembrane:
1) Igomba kuva hasi ikagera kumwanya muremure, idakwega cyane, hasigara intera ya 1,50% yo kurohama no kurambura. Urebye uko ibintu byifashe muri uyu mushinga, ahahanamye hazashyirwa hejuru-hasi.
2) Ihuriro rirerire ryamakadiri yegeranye ntirigomba kuba kumurongo umwe utambitse kandi rigomba kunyeganyezwa na 1M zirenze imwe.
3) Ihuriro rirerire rigomba kuba byibura metero 1,50 uvuye ku kirenge cyurugomero no kugoreka ikirenge, kandi kigomba gushyirwa hejuru.
4) Tangira utangire hepfo yinyuma.
5) Iyo ushyize ahahanamye, icyerekezo cya firime kigomba kuba kibangikanye cyane n'umurongo uhanamye.
Gushyira ahahanamye: Mbere yo gushyira anti-seepage geomembrane kumurongo, ahantu hashyirwa hagomba kugenzurwa no gupimwa. Ukurikije ubunini bwapimwe, anti-seepage membrane ihuye nubunini mububiko igomba kujyanwa mukiciro cya mbere cya anchoring umwobo. Mugihe cyo gushira, uburyo bworoshye bwo "gusunika no kurambika" kuva hejuru kugeza hasi bigomba gukoreshwa ukurikije uko ibintu bimeze kurubuga. Mu gace kameze nkabafana, bigomba gucibwa mu buryo bushyize mu gaciro kugira ngo impande zombi zo hejuru no hepfo zifatanye neza.

Gushyira hasi: Mbere yo gushyira anti-seepage geomembrane, ahantu hashyirwa hagomba kugenzurwa no gupimwa. Ukurikije ubunini bwapimwe, anti-seepage membrane ihuye nubunini mububiko igomba kujyanwa kumwanya uhuye. Iyo urambitse, usunikwa nintoki mu cyerekezo runaka. Guhuza no guhuza: Gushyira geomembrane ya HDPE, haba ahantu hahanamye cyangwa hepfo yurubuga, bigomba kuba byoroshye kandi bigororotse, birinda iminkanyari n’imivurungano, kugirango bihuze kandi bihuze geomembrane ebyiri. Ubugari bwuzuye ni 10cm kumpande zombi ukurikije igishushanyo mbonera.
Kanda firime: Koresha imifuka kugirango ukande mugihe cya geomembrane ya HDPE ihujwe kandi ihujwe kugirango wirinde umuyaga no gukurura.
Kurambika mu mwobo wa Anchoring: Umubare munini wa anti-seepage membrane ugomba kubikwa hejuru yumwobo wa ankeri ukurikije ibyashizweho kugirango witegure kurohama no kurambura.
Ihuriro rirerire: Igice cyo hejuru kiri hejuru, igice cyo kumanuka kiri hepfo, kandi hariho uburebure buhagije = 15cm. Nyuma yo kwemererwa gushira bentonite, agace gashyizwe nintoki mu cyerekezo runaka.
