Hiki ke kapa ʻia ʻo nā mea kikowaena palaki he mau pahu kila. Hoʻohana pinepine ʻia lākou me nā kaola kila, e like me nā heleuma hollow, a me nā nati, pallets, drill bits a me nā mea ʻē aʻe e loaʻa ai nā hopena grouting maikaʻi aʻe. Ma muli o nā hiʻohiʻona o kāna mea ponoʻī, ʻo kēia huahana he corrosion-resistant, kiʻekiʻe-mehana kūʻokoʻa, māmā-kaumaha, haʻahaʻa haʻahaʻa, a maʻalahi hoʻi e hoʻokomo, mālama i ka nui o ka manawa a me nā koina hana.
ʻO nā mea kikowaena maʻamau no nā lāʻau heleuma i hana ʻia me ka plastic a he keʻokeʻo ka nui o ka waihoʻoluʻu. Hiki ke hoʻohana me ka precision-rolled rebar, heleuma koʻokoʻo, nā kaula kila, rebar a me nā huahana ʻē aʻe. Hiki ke hoʻohana ʻia i ka ʻenekinia mea kanu nuklea, mālama wai a me hydropower, kūkulu hale a me nā māla ʻē aʻe.
