Ko te tāke rokiroki e whakamahia ana hei penapena i ngā ipu hiri maitai, wai rānei, hau rānei. Ko te hangarau o te tāke rokiroki he hinu, matū, witi me te hinu, kai, tiaki ahi, kawe waka, whakarewa, tiaki whenua me ētahi atu ahumahi he mea nui ki ngā hanganga, he tino pakari hoki ōna whakaritenga taketake. Me tutuki te paparanga oneone turanga i ngā whakaritenga o te uara hoahoa o te kaha kawe, ā, me rongoa ki te wai turuturu me te ātete makuku, ki te kore ka pāngia te taiao e te turuturu, ā, ka puta ake te mamaoa wai o raro whenua, ā, ka waikura te tāke maitai. Nō reira, ko te geomembrane ātete-wai HDPE te rauemi ātete-wai me te ātete-makuku i roto i te hoahoa taketake o te tāke rokiroki.
Te hangarau hanga geomembrane ātete-wai mō te whakatakoto i te rohe tāke hinu:
1. I mua i te whakatakotoranga o te geomembrane ā-roto o te tāke hinu, me tiki te tiwhikete whakaae e tika ana mō te miihini ā-iwi.
2. I mua i te tapahi, me ine tika ngā inenga e tika ana, me tapahi te geomembrane HDPE kia rite ki te tapahi tuturu, kaua e rite ki te rahi e whakaaturia ana, me tau takitahi, ā, me tuhi taipitopito ki te puka motuhake.
3. Me whai kia iti ake te whakarewa, kia pai ai te kounga, kia taea ai te penapena rauemi mata. He ngāwari hoki te whakarite i te kounga.
4. Ko te whānui o te hononga i waenganui i te kiriata me te kiriata, kāore i te iti iho i te 10cm, kia rite te tūnga o te hononga whakarewa ki te pari, arā, i te pari.
5. I ngā kokonga me ngā wāhanga kua hē te āhua, me poto te roa o te tuitui. Haunga ngā whakaritenga motuhake, i ngā pari he nui ake i te 1:6 te pari, i roto i te 1.5 mita o te pari o runga, o te wāhi kukū ahotea rānei, ngana kia kaua e tāutahia he whakarewa.
6. Me karo i ngā takai horihori i te whakatakotoranga o te ipu hinu kia kore e uru. Mēnā he iti te pāmahana, me whakakīkī, me whakatakoto kia tawhiti rawa atu.
7. I muri i te whakatakotoranga o ngā geomembrane kore-uru, me whakaiti te hikoi i runga i te mata o te membrane, te neke taputapu, me ētahi atu. Kaua e whakatakotoria ki runga i te membrane, kaua hoki e haria ki runga i te membrane ngā mea ka pā kino ki te membrane kore-uru kia kore ai e pakaru te membrane.
