Geotextile raranga papatahi kirihou
Ko te geotextile te raranga he mea raranga mai i te riipene polypropylene me te polypropylene ethylene hei rauemi mata.E whakamahia nuitia ana i roto i te hangarau hangarau penei i te tiaki wai, te hiko hiko, te whanga, te huarahi nui me te hanga tereina.
1. Te kaha teitei Na te whakamahi i te waea papatahi kirihou, ka taea e ia te pupuri i te kaha me te elongation i roto i nga ahuatanga maroke me te makuku.
2. Te aukati waikura Ka taea e ia te aukati i te waikura mo te wa roa i roto i te oneone me te wai he rereke te pH.
3. He pai te uruhanga wai He waahi kei waenganui i nga waea papatahi, na reira he pai te uruhanga wai.
4. He pai nga taonga anti-microbial, kaore he kino ki nga microorganisms me nga moths.
5. Te hanga watea Na te mea he maamaa me te ngawari te rauemi, he pai mo te kawe, te whakatakoto me te hanga.
