2. Ki te whakatauritea ki ētahi atu momo rauemi whakamahana taura, ehara i te mea he iti noa te utu o te waea me te taura kua whakamahanatia ki te PVC, engari he rerekētanga tae o te mata, te pōuri o te mārama, te pai o te tā, te pai o te tukatuka, te pakeke, te piri o te ara iahiko, ngā āhuatanga ā-tinana me ngā āhuatanga hiko o te waea tonu, me ētahi atu. Ka taea te whakahaere pai i ngā āhuatanga katoa; he tino pai ngā āhuatanga ātete mura, nō reira ka taea e ngā waea me ngā taura kua whakamahanatia ki te PVC te eke ki ngā taumata ātete mura kua whakaritea i roto i ngā paerewa rerekē.
3. Ko te waea kei roto i te awhe taumaha kua tohua. Ko te hipoki i whakamahia i roto i te waea kakahu he whakamarumaru polyvinyl chloride. Me maeneene te āhua o te whakamarumaru waea, me te tānga mata mārama. Mai i te pito o te waea, me ōrite te whakamarumaru, kaua e rerekē.
