Ko ngā rauemi ātete wai hou ko te nuinga o te rauemi takai ātete uku rapa, te rauemi takai ātete polymer, te paninga ātete wai, te rauemi hiri, te rauemi mono, me ētahi atu. I roto i ēnei, ko te rauemi takai ātete wai te rauemi ātete wai e whakamahia nuitia ana, e whakamahia ana mō te tuanui me te turanga ātete wai, me ngā āhuatanga o te hanganga watea me te utu mahi iti. He aha ngā painga me ngā ngoikoretanga o te rauemi ātete wai hou? Ngā painga me ngā ngoikoretanga o te rauemi takai ātete wai polymer. Ko ngā painga o te rauemi takai ātete wai ko: te hanganga watea, te wā hanga poto, te kore tiaki i muri i te hanganga, te kore pānga o te pāmahana, te iti o te parahanga taiao, te matotoru o te paparanga ngāwari ki te pupuri i runga i ngā whakaritenga o te mahere pā, te tatau rauemi tika, te whakahaere papahanga watea, te kore e ngawari ki te tapahi, me te matotoru o te paparanga ōrite, ka taea te whakakore i te ahotea o te papa turanga i te wā e takoto kau ana te papa (ka taea te pupuri i te paparanga ātete wai katoa mēnā he nui ngā kapiti i roto i te papa turanga). Ngā ngoikoretanga o te rauemi takai ā-wai: hei tauira, ina inehia te rauemi takai ā-wai, ā, ka tapahia kia rite ki te āhua o te papa turanga ā-wai i roto i te hanganga ā-wai, ka hiahiatia he maha ngā hononga mō te papa turanga he āhua uaua, ā, he uaua te here o ngā wāhanga taupatupatu o te rauemi takai ā-wai, nā te mea ka pā te maha o ngā hononga ki te ataahua o te paparanga ā-wai; Heoi anō, ko te hiri katoa me te tino ka waiho hei raruraru matua. Ko te hononga o te rauemi takai te mea nui rawa atu te mōrearea me te tūponotanga o te turuturu wai; Heoi anō, he maha ngā tau o te pakari o ngā rauemi takai ā-wai kounga teitei, engari he iti noa ngā piripiri e rite ana i Haina. Ngā painga o te rauemi takai ā-wai uku rapa: ko te rauemi takai ā-wai uku whakarerekētia elastomer he rauemi takai ā-wai uku whakarerekētia hiato i hangaia ki te polyester felt hei turanga potae, ā, kua pania ki te uku whakarerekētia elastomer me te uku whakarerekētia kirihou i ngā taha e rua. Nā te mea e hipokina ana e ia ngā momo rauemi paninga e rua i te wā kotahi, ka whakakotahihia e te hua ngā painga o te uku kua whakarerekētia e te elastomer me te uku kua whakarerekētia e te kirihou, e kore e whakakore noa i ngā hapa o te ātete wera ngoikore me te ātete hurihuri o te rauemi takai ā-waikura uku kua whakarerekētia e te elastomer, engari e whakakapi ana hoki i ngā hapa o te ngāwari pāmahana iti ngoikore o te rauemi takai ā-waikura uku kua whakarerekētia e te kirihou. Nō reira, he pai mō te hangarau ā-waikura rori me te piriti i ngā wāhi makariri rawa o te raki, tae atu ki te hangarau ā-waikura tuanui i ngā wāhi āhuarangi motuhake pēnei i te rerekētanga pāmahana teitei, te teitei teitei, te ultraviolet kaha me ētahi atu.
