Matapihi muka karāhe
Ko te mata whenua muka karāhe he momo mata whenua i hangaia mā te whakamahi i te muka karāhe hurihuri kore-waikawa, kāore i mirohia hei rauemi matua. Ka hangaia tuatahitia hei rauemi hanganga kupenga mā te tukanga raranga motuhake, kātahi ka pania ki te mata. He kaha teitei te muka karāhe, he teitei te modulus, he iti te roa, e whakarato ana i te turanga pai mō ngā āhuatanga miihini o te mata whenua.

Matawhenua maitai-kirihou
Ko te geogrid maitai-kirihou ka whakamahia ngā waea maitai kaha-teitei (ngā muka rānei) hei anga matua mō te tautoko ahotea. Whai muri i te maimoatanga motuhake, ka honoa ki ngā kirihou pērā i te polyethylene (PE) polypropylene (PP) me ētahi atu tāpiringa, ā, ka hangaia he rīpene kume kaha-teitei mā te tukanga whakaputa. Ko te mata o te rīpene he tauira whakairo taratara. Kātahi ka whatua, ka piri rānei ia rīpene ki te taha roa me te taha whakararo i tētahi mokowā, ā, ka whakarewahia ngā hononga mā te hangarau hononga me te whakarewa whakakotahi motuhake hei hanga i te geogrid maitai-kirihou. -
Matapihi Kirihou Totoro Biaxially
He rauemi geosynthetic momo hou tēnei. Ka whakamahia ngā polymer ngota-teitei pērā i te polypropylene (PP) polyethylene rānei (PE) hei rauemi mata. Ka hangaia ngā pereti mā te whakakirihou me te whakaputa, kātahi ka werohia, ā, i te mutunga ka totorohia kia roa, kia anga whakarara hoki. I te wā o te tukanga hanga, ka whakaritea anōtia ngā mekameka ngota-teitei o te polymer, ka whakatakotoria hoki i te wā e wera ana, e totoro ana te rauemi. Mā tēnei ka whakapakari ake i te hononga i waenga i ngā mekameka ngota, ā, ka piki ake tōna kaha. Ko te tere whakaroa he 10% – 15% noa iho o te tere whakaroa o te pereti taketake.

Kirihou Geogrid
- He mea hanga te nuinga mai i ngā rauemi pūmua ngota-teitei pērā i te polypropylene (PP) me te polyethylene (PE). Ki te titiro atu, he rite te hanganga ki te mata. Ka hangaia tēnei hanganga mata mā roto i ngā tukanga hanga motuhake. I te nuinga o te wā, ka hangaia te rauemi mata o te pūmua hei pereti, kātahi mā roto i ngā tukanga pērā i te wero me te totoro, ka hangaia he mata whenua me te mata whenua noa. Ka taea te tapawhā, te tapawhā rite, te āhua taimana, me ētahi atu te āhua o te mata whenua. Ka rerekē te rahi o te mata whenua me te matotoru o te mata whenua i runga i ngā whakaritenga hangarau me ngā paerewa hanga motuhake.

Uniaxially – he whatunga whenua kirihou kua totorohia
- Ko te geogrid kirihou totoro-kore-axial he momo rauemi geosynthetic. Ka whakamahia e ia ngā polymer ngota-teitei (pērā i te polypropylene, te polyethylene matotoru-teitei rānei) hei rauemi mata matua, ā, ka tāpirihia hoki ngā tāpiringa ārai-ira-kore, ārai-pakeketanga me ētahi atu. Ka tukuna tuatahitia ki roto i tētahi pereti angiangi, kātahi ka werohia he kupenga poka noa ki runga i te pereti angiangi, ā, i te mutunga ka totorohia ki te taha roa. I te wā o te tukanga totoro, ka hurihia ngā mekameka ngota o te polymer ngota-teitei mai i te āhua taketake kāore i te tino pai, ka hangaia he hanganga whatunga porowhita-ahua me ngā pona kaha-teitei kua tohatohahia.
