E toru ngā raupapa matua o ngā geotextiles:
1. Geotextile kore-whatu i werohia ki te ngira
E ai ki te rauemi, ka taea te wehewehe i ngā geotextile kore-whatu me te wero ngira ki ngā geotextile polyester me ngā geotextile polypropylene; ka taea hoki te wehewehe ki ngā geotextile muka roa me ngā geotextile muka poto. Ko te geotextile kore-whatu me te wero ngira he mea hanga ki te muka polyester, ki te muka polypropylene rānei mā te tikanga wero ngira, ko te whakatakotoranga e whakamahia whānuitia ana ko te 100g/m2-1500g/m2, ā, ko te kaupapa matua ko te tiaki i ngā pari o te awa, te moana, me te roto, te whakahaere waipuke me te whakaora ohorere, me ētahi atu. He huarahi whai hua ēnei hei pupuri i te wai me te oneone me te ārai i te rere o ngā paipa mā te tātari whakamuri. Ko ngā geotextile muka poto ko ngā geotextile polyester me te wero ngira me ngā geotextile polypropylene, he geotextile kore-whatu ēnei e rua. He pai te ngāwari, te ātete ki te waikawa me te kawakore, te ātete ki te waikura, te ātete ki te koroheketanga, me te hanganga watea. Ko te whānui o ngā geotextile muka roa he 1-7m me te taumaha he 100-800g/㎡; He mea hanga ēnei ki ngā miro muka roa polypropylene, polyester rānei, he kaha te kaha, he mea hanga ki ngā tikanga motuhake, ā, he ātete ki te kakahu, he ātete ki te pahū, ā, he kaha kume teitei.
2. Kakahu whenua hiato (Kakahu kore-whatu i werohia ki te ngira + kiriata PE)
Mā te whakakotahi i ngā papanga kore-whatu me ngā kiriata PE, ka hangaia ngā geotextile hiato ki te muka poto polyester, ā, ka wehea ēnei ki: "kotahi te papanga + kotahi te kiriata" me "e rua ngā papanga me te kotahi te kiriata". Ko te kaupapa matua o te geotextile hiato he ārai i te turuturu, he pai mō ngā rēriwe, ngā huarahi tere, ngā kauhanga, ngā ara raro whenua, ngā taunga rererangi, me ētahi atu kaupapa.
3. Ngā geotextiles kore-whatu me te whatu hiato
He mea hanga tēnei momo kākahu whenua mai i te papanga kore-whatu i werohia ki te ngira me te papanga whatu kirihou. Ko te nuinga o te wā e whakamahia ana mō te whakapakari i te turanga me ngā whare hangarau taketake mō te whakarerekē i te tauwehenga uruhanga.
