ʻO nā mea i hoʻopili ʻia i ka wai ponoʻī he ʻano mea wai i hana ʻia me ka asphalt paʻa paʻa ponoʻī i hoʻomākaukau ʻia mai SBS a me nā ʻāpana synthetic ʻē aʻe, tackifier a me ke ala kiʻekiʻe o ke ala ʻaila asphalt e like me ke kumu kumu, ikaika a paʻakikī kiʻekiʻe kiʻekiʻe polyethylene film a i ʻole alumini alumini. e like me ka ʻikepili ili luna, a me ka peelable silicon coated diaphragm a i ʻole ka pepa pale silikona i uhi ʻia e like me ka ʻike haʻahaʻa anti-adhesive pale.

He ʻano mea wai hou ia me ka manaʻo hoʻomohala nui. Loaʻa iā ia nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa haʻahaʻa, hoʻōla ponoʻī a me ka hana hoʻopaʻa maikaʻi. Hiki ke kūkulu ʻia i ka lumi wela, ka wikiwiki o ke kūkulu ʻana a hoʻokō i nā koi o ka mālama ʻana i ke kaiapuni. ʻO nā mea i hoʻopili ʻia ʻo ia iho he mea hoʻopili ponoʻī ʻia me ka resin molecular kiʻekiʻe a me ka asphalt kiʻekiʻe e like me ke kumu kumu, polyethylene film a me ka alumini alumini e like me ka ʻike hiʻohiʻona, a me kahi papa hoʻokaʻawale.
Loaʻa i ka huahana ka hana hoʻopaʻa paʻa a me ka ho'ōla ponoʻī, a kūpono no ke kūkulu ʻana i ke kiʻekiʻe a me ka haʻahaʻa wela. Hiki ke hoʻokaʻawale ʻia i ka paʻa paʻa paʻa a me ka paʻa paʻa ʻole. Hoʻokumu ʻia ka huila me nā kikowaena paʻa ponoʻī luna a me lalo i hoʻopaʻa ʻia me ke kumu pila. ʻO ka uhi kiʻekiʻe he vinyl film a ʻo ka uhi haʻahaʻa he peelable silicone oil film. Hoʻopili ʻia ka paʻi paʻa paʻa kūʻokoʻa me ka paʻa ponoʻī, ke kiʻi vinyl luna a me ke kiʻi ʻaila silicone haʻahaʻa.
Loaʻa i ka huahana ka hana haʻahaʻa haʻahaʻa maikaʻi. ʻO ia ka ʻikepili wai wai maikaʻi loa, ka ʻūlū a me ka hoʻopaʻa ʻana i ka ʻikepili no ka subway, tunnel a me kahi kahua hana wela. He kūpono no ka pipeline wai a me ka ʻenehana anti-corrosion. ʻAʻohe pono no ka hoʻoheheʻe ʻana a i ʻole ka wela e hoʻoheheʻe. Wehe wale i ka papa pale a hiki ke hoʻopaʻa paʻa i ka papa lalo. He maʻalahi ke kūkulu ʻana a wikiwiki loa ka wikiwiki o ke kūkulu ʻana.
