Chophimba chapamwamba cha bulangeti losatsekedwa ndi madzi ndi filimu yochuluka kwambiri ya polyethylene (HDPE) ndipo pansi ndi nsalu yopanda nsalu. Chofunda cha sodium bentonite chopanda madzi chokhala ndi madzi abwino kwambiri chimakhazikika pakati pa geotextiles amphamvu kwambiri pogwiritsa ntchito njira yapadera yokhomerera singano ndikuyika pansalu yopanda nsalu. Filimu ya polyethylene yapamwamba kwambiri (HDPE) imatsatiridwa. Chofunda chopanda madzi cha Bentonite chili ndi mphamvu zopanda madzi komanso zotsutsana ndi masamba kuposa bulangeti wamba lopanda madzi la bentonite. Njira yotetezera madzi ndi yakuti bentonite particles imakula pamene imalowa m'madzi, ndikupanga yunifolomu ya colloid. Pansi poletsa magawo awiri a geotextile, bentonite imakula kuchoka kuchisokonezo kupita ku dongosolo. Chotsatira cha kuyamwa madzi mosalekeza ndi kukulitsa ndi kupanga bentonite wosanjikiza wokha wandiweyani. , motero zimakhala ndi mphamvu yoletsa madzi.

Maonekedwe a bulangeti losalowerera madzi:
1. Ili ndi zinthu zabwino kwambiri zopanda madzi komanso zotsutsa-seepage, kuthamanga kwa anti-seepage hydrostatic kumatha kufika kupitirira 1.0MPa, ndipo mphamvu ya permeability ndi 5 × 10-9cm / s. Bentonite ndi zinthu zachilengedwe zopanga zinthu zomwe sizingakumane ndi ukalamba ndipo zimakhala zolimba; ndipo sizidzatero Kusokoneza kulikonse pa chilengedwe ndi zinthu zachilengedwe
2. Zili ndi zizindikiro zonse za zipangizo za geotextile, monga kupatukana, kulimbikitsa, chitetezo, kusefera, ndi zina zotero. Ndizosavuta kumanga ndipo sizimaletsedwa ndi kutentha kwa chilengedwe. Itha kumangidwanso pansi pa 0 ℃. Pomanga, mumangofunika kuyala bulangeti lopanda madzi la GCL pansi. Pomanga pa facade kapena malo otsetsereka, ikonzeni ndi misomali ndi makina ochapira, ndikuphatikizana ngati pakufunika.
3. Zosavuta kukonza; ngakhale pambuyo pa kumangidwa kwa madzi (seepage) kumalizidwa, ngati wosanjikiza madzi akuwonongeka mwangozi, malinga ngati gawo lowonongeka limangokonzedwanso, ntchito yowonongeka yowonongeka ikhoza kubwezeretsedwanso.
4. Chiŵerengero cha ntchito-mtengo ndi chokwera kwambiri ndipo chimakhala ndi ntchito zambiri.
5. Kuchuluka kwa mankhwala kumatha kufika mamita 6, omwe amafanana ndi geotextile (membrane) yapadziko lonse lapansi, kupititsa patsogolo ntchito yomanga bwino.
6. Ndikoyenera kuchitira anti-seepage and leakge treatment m'madera omwe ali ndi zofunikira zoletsa madzi komanso zotsutsana ndi zowonongeka, monga ngalande, subways, zipinda zapansi, ndime zapansi, nyumba zosiyanasiyana zapansi ndi mapulojekiti amadzi okhala ndi madzi olemera apansi.
