I te tipu haere o tō tātou ōhanga ā-motu me te whakapainga o ngā paerewa oranga, kua whānui haere te whakamahinga o ngā kiriuhi geotextile. Heoi, ahakoa mō te momo kiriuhi geotextile kotahi, ka rerekē te roa o te whakamahinga i runga i te wāhi me ngā āhuatanga mahi. Nō reira, me pēhea te whakamahi tika i ngā kiriuhi geotextile kia roa ai te whakamahinga? I tēnei rā, me tūhura tātou i ngā whakatūpato matua hei whai mā te whakamahi i ēnei rauemi.
I te wā e whakamahi ana i ngā kiriuhi geotextile, he mea tino taunaki kia whakaitihia te pānga ki te mārama. Mena ka taea te tiaki pai i te kiriuhi mai i te mārama i te wā e ora ana, ka whakaratohia he taurangi nui mō te roa o tōna roa.
I te wā e tāuta ana, me whakatakoto te kiriuhi kia ngawari te ngokingoki, kia taea ai te whakawhānui me te whakawhāiti; kāore e tino āraia te totoro nui. Ka taea e ngā piki me ngā heke o te pāmahana me te oneone te whakangawari i ngā kiriuhi kia pakari; mā te whakatakoto i te kiriuhi kia ngawari te ngokingoki ka whakaiti i aua tūponotanga. Ko te mea pai, me haere tonu te tāutanga ki raro i te pari—mai i runga ki raro—kia iti ai te maha o ngā hononga whakawhiti. Me tutuki te whānui o te taupatupatu i waenga i ngā pepa kiriuhi tata ki ngā paerewa kua whakaritea: kaua e iti iho i te 10 cm te whānui o ngā taupatupatu whakarewa, ko ngā taupatupatu here kaua e iti iho i te 15 cm te whānui.
Me mau ngā kaimahi hanga i ngā hu ngohengohe i te wā e mahi ana; kāore e whakaaetia te hikoi i runga i te kiriuhi i roto i ngā pūtu pakari, i ngā hu rānei he whao e kitea ana. Me tino tupato te whakahaere i ngā taputapu hanga kia kore ai e taka nui. Kāore e whakaaetia te taraiwa tika i ngā mīhini me ngā waka taumaha ki runga i te kiriuhi geotextile; mēnā e tika ana ēnei mahi, me whakatakoto tuatahi ngā papa tiaki rangitahi—pērā i ngā papa rakau, i ngā putea onepu rānei. Hei tāpiri, me tino aroturuki i ngā āhuatanga o te rangi i te wā hanga. Kāore e whakaaetia ngā mahi tāutanga me te whakarewa i te wā ua, i te wā kohu rānei, i ngā hau e neke ake ana i te Mana 5, i te wā rānei e heke iho ana te pāmahana taiao i raro i te 5°C, kia kore ai e pakaru te kiriuhi i te hau, kia tutuki rānei te kounga whakarewa i ngā paerewa e hiahiatia ana.
Kia oti te kaupapa hangarau te whakatū, me whakatū he tikanga mō te tirotiro ā-wā. Me aro nui ki ngā wāhi tino nui pērā i ngā hononga whakarewa, ngā pūwāhi whakawhiti pari, me ngā rohe e pupū ake ana te wai, hei tirotiro mō ngā tohu kino, te pupuhi, te ngatata i puta mai i te taunga, te urunga pakiaka rānei. I roto i te rohe ārai-uru, ka tino āraia ngā mahi pērā i te pana pou, te keri, te tōia rānei i ngā mea pakeke hei ārai i ngā kino tūpono i puta mai i ngā mahi a te tangata.
Mō ngā tono motuhake—pērā i ngā wāhi ururua whenua, i ngā roto pupuri matū rānei—he mea nui kia whiriwhiria ngā kiriuhi geotextile i hangaia mō te ātete ki te waikura me ngā āhuatanga ārai-pakeke, me te whakahaere whakamātautau mahi ā-wā i runga i te rauemi membrane. Me whakatika tonu tetahi kino iti kua kitea kia kore ai e horapa te turuturu, kia mau tonu ai te pumau me te pono o te pūnaha ātete-wai. E whakanui ana ngā tohunga ahumahi, ina tae ki te whakamahinga o ngā geomembranes, kāore he taipitopito e tino iti ana; ko ia āhuatanga e pā tika ana ki te kounga o te kaupapa me te haumaru taiao. Me piri pono ngā kaiwhakatū me ngā kaiwhakamahi mutunga ki ngā tikanga me ngā paerewa kua whakatūria, me te whakatinana i ngā mana whakahaere whānui puta noa i te tukanga katoa, kia tino whakamahia ai te ātete-wai o ngā geomembranes me te whakapakari i te "ara ora ātete-wai" o te kaupapa.
