Ko tētahi ko te tiaki taiao, ko ngā āhuatanga o te muka basalt he tiaki rauemi, he atawhai hoki i te taiao.Ngā muka pātarati "I ahu mai i ngā kōhatu tūturu, ā, e whakamahia ana i roto i ngā kōhatu horihori. Ka haere mai, ka haere atu ngā kōhatu." Ina koa, ko te muka pātarati he muka tonu i hangaia mai i te pātarati tūturu hei rauemi mata, ka rewahia i te pāmahana teitei o te 1450°C ki te 1500°C, kātahi ka tere te kume mā roto i te hu kume koranu platinum-rhodium. I te roanga o te tukanga whakaputa katoa, kāore he wai para ahumahi, he hau para rānei, ā, ko te whakaputanga o ētahi atu para ahumahi e mōhiotia ana ko "ngā rauemi hou o te rautau 21".
Tuarua, ki te whakatauritea ki ētahi atu momo muka pēnei i te muka lignin me te muka karāhe, he teitei ngā tohu hangarau mō te whakamahinga rori, ā, he tino pai te ātete ki te pāmahana teitei, te ātete ki te pāmahana iti, te pumau matū, te mahi ātete-pakeke, te pumau wai, me te mahi ārai hiko. E ai ki ngā rangahau ariā o nāianei, te rangahau pūtaiao me te hangarau, me te tono hangarau, kua tino pakari te tukanga whakaputa me te hangarau o te muka basalt mō ngā rori, ka taea te whakaiti i te kino o ngā kapiti me ngā awaawa i runga i te mata o te rori, te whakaroa i te roa o te mahi o te mata o te rori, me te whakapai ake me te whakarei ake i te hanganga papa. He nui ngā pānga o te mahi ngenge, te pumau pāmahana teitei, te ātete ki te kapiti pāmahana iti me te pumau wai. I te wa ano, he maha ngā momo tono o ngā rauemi pēnei i te miro tapatapahi, te geotextile, te geogrid, te whakapakari hiato, me ētahi atu, e whakaatu ana i te pai o te mahi rori me ngā tumanakohanga tono.
Tuatoru, he whānuitia te whakamahinga o te muka o te papare, tae atu ki ngā mahi hangarau ā-iwi, te hanga waka, te hanga rori, me ētahi atu.
