Hoʻohana nui ʻia ʻo Fiberglass i nā mea wai wai, a ʻo kāna mau hiʻohiʻona māmā, ikaika a paʻa i alakaʻi i ka hoʻomaikaʻi nui ʻana i ka maikaʻi o nā mea wai. Hoʻohana ʻia ʻo Fiberglass ma ke ʻano he mea hoʻoikaika i nā pale wai maʻamau, nā membrane wai a me nā mea hoʻopili wai. ʻO Fiberglass i hui pū ʻia me ka pena, i uhi ʻia ma ka ʻili o ka hale, e hana ana i kahi papa o ka pale ikaika a paʻa, e pale pono i ka komo ʻana o ka wai; ʻO ka fiberglass i hoʻoikaika ʻia i ka membrane waterproofing me ka pale wai, ke kū ʻana o ka wā, ke kū anuanu, ke kū ʻana i ka wela, akā kūʻē i ka deformation flexural a me ka haehae ʻana a me nā kūlana ʻē aʻe; ʻO ka hoʻohana ʻana i ka fiberglass ma ke ʻano he mea hoʻoikaika no ka hoʻopili ʻana i ka wai hiki ke hoʻomaikaʻi maikaʻi i ka ikaika hoʻopaʻa ʻana o nā membrane waterproofing, no laila e hoʻonui ai i kāna hana wai. Eia kekahi, ʻo ka fiberglass ka mea pale ahi, ʻaʻahu a me nā ʻano ʻē aʻe, no laila ua hoʻomaikaʻi ʻia ka maikaʻi o ka wai.
