ʻO nā mea wai ʻole hou e komo pū ana me ka mea wili ʻakika elastic, ka mea wili ʻakika polymer, ka uhi ʻana i ka wai ʻole, ka mea sila, ka mea hoʻopili, a pēlā aku. I waena o lākou, ʻo ka mea wili ʻakika wai ʻole ka mea wai ʻole i hoʻohana nui ʻia, kahi i hoʻohana nui ʻia no ka uhi ʻana i ka hale a me ke kumu, me nā ʻano o ke kūkulu kūpono a me ke kumukūʻai hana haʻahaʻa. He aha nā pōmaikaʻi a me nā hemahema o ka mea wai ʻole hou? Nā pōmaikaʻi a me nā hemahema o ka mea wili ʻakika wai ʻole polymer. ʻO nā pōmaikaʻi o ka mea wili ʻakika wai ʻole: kūkulu kūpono, wā kūkulu pōkole, ʻaʻohe mālama ma hope o ke kūkulu ʻana, ʻaʻohe mana o ka mahana, ka haumia liʻiliʻi o ke kaiapuni, ka mānoanoa o ka papa maʻalahi e paʻa e like me nā koi o ka hoʻolālā hoʻoikaika, ka helu pololei ʻana i nā mea, ka hoʻokele kahua kūkulu kūpono, ʻaʻole maʻalahi ke ʻoki ʻia i nā kihi, a me ka mānoanoa like o ka papa, hiki ke lanakila maikaʻi i ke kaumaha o ka papa kumu i ka wā o ka paving hakahaka (hiki ke mālama ʻia ka papa wai ʻole holoʻokoʻa inā he mau māwae nui i ka papa kumu). ʻO nā hemahema o ka mea wili wai ʻole: no ka laʻana, i ka wā e ana ʻia ai a ʻokiʻoki ʻia ka mea wili wai ʻole e like me ke ʻano o ke kumu papa wai ʻole i loko o ke kūkulu wai ʻole, pono nā splices he nui no ke kumu papa me ke ʻano paʻakikī, a he paʻakikī ka hoʻopaʻa ʻana o nā ʻāpana overlapping o ka mea wili wai ʻole, no ka mea, hoʻopilikia ka splices he nui i ka nani o ka papa wai ʻole; Eia kekahi, ʻo ka sila piha a piha e lilo i pilikia nui. ʻO ka hui lap o ka mea wili ka mea huna nui loa a me ka manawa kūpono o ka liki wai; Eia kekahi, he mau makahiki o ka lōʻihi o nā mea wili wai ʻole kiʻekiʻe, akā he kakaikahi nā mea hoʻopili kūpono ma Kina. Nā pono o ka mea wili wai ʻole asphalt elastic: ʻo ka mea wili wai ʻole asphalt elastomer composite modified he mea wili wai ʻole asphalt i hana ʻia me ka polyester felt e like me ke kumu o ka huila a uhi ʻia me ka asphalt modified elastomer a me ka asphalt modified plastic ma nā ʻaoʻao ʻelua. Ma muli o ka uhi ʻana i ʻelua ʻano mea uhi i ka manawa like, hoʻohui ka huahana i nā pono o ka elastomer modified asphalt a me ka plastic modified asphalt, ʻaʻole wale e lanakila i nā hemahema o ke kūpaʻa wela maikaʻi ʻole a me ke kūpaʻa ʻōwili o ka elastomer modified asphalt waterproof coiled material, akā e uku pū ana hoʻi no nā hemahema o ka haʻahaʻa haʻahaʻa haʻahaʻa o ka plastic modified asphalt waterproof coiled material. No laila, kūpono ia no ke alanui a me ke alahaka waterproof engineering ma nā wahi anuanu koʻikoʻi ma ka ʻākau, a me ka hale waterproof engineering ma nā wahi aniau kūikawā e like me ke kiʻekiʻe o ka mahana, ke kiʻekiʻe kiʻekiʻe, ka ultraviolet ikaika a pēlā aku.
