He momo rauemi hiato te pereti mamau, ko te waku te mahi matua me ngā whakaritenga hanganga. Ko ngā rauemi waku waka e whakamahia ana i te nuinga o te wā i roto i te hanga pereti waku parai me te pereti mamau. Ko ēnei rauemi waku he mea whakamahi i ngā rauemi waku e ahu mai ana i te asbestos, ā, i te piki haere o ngā whakaritenga mō te tiaki taiao me te haumaru, ka puta haere ngā rauemi waku haurua-whakarewa, ngā rauemi waku muka hiato, me ngā rauemi waku muka uku.
Nā te mea e whakamahia nuitia ana te rauemi waku i roto i te hanga o ngā wāhanga parai me te tuku hiko, me nui, me pumau hoki te tauwehenga waku, ā, me pai hoki te ātete ki te kakahu.
Ko te mamau he momo tikanga e tuku ana i te mana mā te pēhitanga tuaka me te tukunga mā te awhina o ngā pereti waku mamau e rua he mata papatahi. Ko te nui ake o te pēhanga tuaka o ngā pereti mamau e rua, ko te nui ake o te kaha waku e puta ana, ā, ko te pumau me te noa o te mahi a te extruder ka tukuna. I roto i te mahi noa, ko te mīhini e whakaatu ana i te mahi pumau me te kore haruru; i raro i te kawenga kua whakatauria, e kore e paheke te kōpae mamau, e kore e mau, e kore e wetewete; I taua wā anō, i muri i te wehenga o te pereti mamau, me wehe atu hoki i te mīhini pereki kia mutu rawa te oma, kia kore ai he haruru atu, kia kore ai rānei e wehea rawatia ngā pereti mamau e rua, me ērā atu mea. Nō reira, me whakatikatika te mamau i roto i te āputa, ka paheke te kōpae mamau i te āputa, ka kino te kōpae mamau, ka uaua te wehe i te kōpae mamau i te āputa, me ērā atu mea.
