ʻO ka papa luna o ka pākeʻe wai i uhi ʻia he kiʻiʻoniʻoni polyethylene kiʻekiʻe (HDPE) a ʻo ka papa lalo he lole i ulana ʻole ʻia. Hoʻopaʻa ʻia ka pākī wai wai sodium bentonite me ka hopena wai ʻoi aku ka ikaika ma waena o nā geotextiles kiʻekiʻe me ka hoʻohana ʻana i ke ʻano kuʻi kui kui kūikawā a laila kau ʻia ma luna o ka lole i ulana ʻole ʻia. Hoʻopili ʻia kahi papa kiʻiʻoniʻoni polyethylene kiʻekiʻe (HDPE). ʻOi aku ka ikaika o ka pale wai ʻole o Bentonite ma mua o ka pale wai wai bentonite maʻamau. ʻO ke ʻano hana wai wai ʻo ia ka hoʻonui ʻana o nā ʻāpana bentonite i ka wā e ʻike ʻia ai i ka wai, e hana ana i kahi ʻōnaehana colloid like. Ma lalo o ke kaohi ʻana o ʻelua mau papa geotextile, hoʻonui ka bentonite mai kahi maʻi i ke kauoha. ʻO ka hopena o ka hoʻomau ʻana i ka wai a me ka hoʻonui ʻia ʻana e hana i ka papa bentonite ponoʻī. , no laila he hopena wai.

ʻO nā hiʻohiʻona kino o ka pālani wai i uhi ʻia:
1. Loaʻa iā ia nā waiwai wai maikaʻi a me ka anti-seepage, hiki i ka anti-seepage hydrostatic pressure hiki ke piʻi aku ma mua o 1.0MPa, a ʻo ka coefficient permeability ʻo 5 × 10-9cm / s. ʻO ka Bentonite kahi mea kūlohelohe kūlohelohe ʻaʻole e hele i ka hopena o ka wā kahiko a loaʻa ka paʻa maikaʻi; a ʻaʻole ʻO ka hopena maikaʻi ʻole i ke kaiapuni he mea pili kaiapuni
2. Loaʻa iā ia nā hiʻohiʻona a pau o nā mea geotextile, e like me ka hoʻokaʻawale, hoʻoikaika, pale, kānana, a me nā mea ʻē aʻe. Hiki ke kūkulu ʻia ma lalo o 0 ℃. I ka wā o ke kūkulu ʻana, pono ʻoe e waiho i ka pale pale wai GCL ma ka honua. Ke kūkulu ʻia ma ka ʻaoʻao a i ʻole ka pali, e hoʻoponopono iā ia me nā kui a me nā mea holoi, a uhi ʻia e like me ka mea e pono ai.
3. Maʻalahi e hoʻoponopono; ʻoiai ma hope o ka pau ʻana o ke kūkulu ʻana i ka wai wai (seepage), inā i pōʻino ʻole ka papa wai wai, ʻoiai ke hoʻoponopono wale ʻia ka ʻāpana i hoʻopau ʻia, hiki ke hoʻihoʻi hou ʻia ka hana wai ʻole.
4. He kiʻekiʻe ka lākiō hana-kumu kūʻai a loaʻa iā ia ka laulā o nā hoʻohana.
5. Hiki i ka laula huahana ke hiki i ka 6 mika, e like me ka honua geotextile (membrane) kiko'ī, e hoʻomaikaʻi nui i ka hana ʻana.
6. He kūpono ia no ka anti-seepage a me ka leakage lapaʻau ma nā wahi me ka wai kiʻekiʻe a me ka anti-seepage koi, e like me tunnels, subways, basements, underground passages, like ʻole nā ​​hale lalo a me nā papahana wai me nā kumu waiwai wai honua.
