Mō ngā geotextile whānui, ko te mīhini whakarewa hononga-rua te mea nui mō te whakarewa, ā, me whakatika me te whakakaha ētahi wāhanga mā te mīhini whakarewa whakaputa. Ka tika te geomembrane mēnā ka whakatakotoria kia rite ki ngā whakaritenga mō ngā hononga pari me ngā hononga papatahi.
Tirohia mēnā he maeneene, he pakari hoki te mata o raro o te hononga. Mēnā he mea ke kei roto, me whakakore wawe atu. Tirohia mēnā he tika te whānui o te hononga o te whakarewa, ā, me papatahi te geomembrane i te hononga, ā, me pakupaku. Whakamahia he pū wera hei pauna i te taumaha o ngā geomembrane e rua. Kua honoa ngā wāhanga o te puranga. Kaua e neke ake i te 80 mm te tawhiti i waenga i ngā pūwāhi hononga. Whakahaerehia te pāmahana o te hau wera me te kore e whakangaro i te geomembrane.
Kāore he ahunga whakapae o te geomembrane i roto i te whakarewa pari. Me pēhea te whakaaro he tika? Ko te whakatakotoranga o te geomembrane i te pari me te hononga papatahi e whai ana i ngā whakaritenga, arā, he tika. Ko te geomembrane o te pūnaha ārai-mimi o raro ka whakatakotoranga ki te paraikete ārai-wai bentonite, ā, ko te pūnaha ārai-mimi taupoki ka whakatakotoranga tika ki te oneone o ngā toenga para ahumahi. I mua i te whakatakotoranga o te geomembrane, me tirotirohia te papa o raro, ā, me pakari, me papatahi te turanga, me te hohonu poutū o te 25mm, kāore he pakiaka. Ka pā pea te oneone rauropi, te kōhatu, ngā poraka raima me ngā pae maitai ki ngā kongakonga hanga o te geomembrane.
Me whai whakaaro ki te whakarerekētanga o te kume i puta mai i te huringa pāmahana i te wā e whakatakoto ana i te geomembrane. Nā te iti o te kaha o te paninga i te wāhi whakarewa, kaua te whānui o te hononga taupatupatu i waenga i te paninga me te paninga e iti iho i te 15 cm. I raro i ngā āhuatanga noa, me whakarite te ahunga whakatakotoranga hononga i te ahunga pari.
Ko ngā tohutohu kei runga ake nei mō te geomembrane e rite ana ki ngā whakaritenga mō ngā hononga pari me ngā hononga papatahi.
