I patai mai tetahi o taatau kaihoko ki ahau:'Kei te pehea te haere o to mahi mahi?Kei te pai tonu?

e mohio ana ahau he nui te paanga o te tiaki Taiao o Haina ki nga hua matū penei i te whakauru raima i Haina.

Me whakaatu atu ahau ki a koe mai i te timatanga.

E mohio ana tatou katoa, ka tere te whakawhanake a Haina i enei tau, i tenei wa, ka nui haere te raru o te taiao.

Hei whakaurunga raima o te reanga tuarua, te konutai naphthalene formaldehyde, mo ona rawa, he naphthalene me te formaldehyde o te ahumahi.

I te mea he whakaurunga raima reanga hou, polycarboxylate superplasticizer, he haunga kee kei te taha o te tipu polycarboxylate superplasticizer.

Ka mohio te kawanatanga o Haina ehara tenei i te huarahi tika mo te whanaketanga ohaoha. ka timata ratou ki te whakatu roopu tirotiro taiao ki te whakaoti i te raru o te parahanga.

I te mea ko tetahi o nga umanga parahanga taumaha, he maha nga tipu whakangao raima e pa ana ki te whakaurunga raima kaore he raihana pakihi me te kore he huarahi tika i aukatihia te parahanga kia kati.

na tenei ka piki tere te utu mo te whakauru raima. Kei etahi wheketere whakauru raima he ota, engari kaore i te nui nga rawa mo te hanga.

Ka mutu, hei whakau i a koe, ae, he rite tonu ta matou mahi mo te whakauru raima.
