ʻIkepili o nā ʻano ʻenehana o ka hoʻoheheʻe ʻia ʻana o ka paipu kila kila:
1. Hana: ʻO ka paipu grouting he hana wai maikaʻi a hiki ke pale pono i ka leakage wai.
2. Paʻa: He lōʻihi ke ola o ka paipu grouting a ʻaʻole e ʻino i ka wā lōʻihi.
3. Ke kū'ē i ka corrosion: No ka mea aia nā mea polymer a me nā mea hoʻohui, ʻoi aku ka kiʻekiʻe o kona kūpaʻa waikawa a me ka alkali.
4. Paʻa paʻa paʻa: Paʻa paʻa ikaika, hiki ke hoʻemi i ka lole mechanical.
5. Ka palekana a me ka hilinaʻi: No ka mea, ua hana ʻia me ke kila ikaika a i ʻole ke kila kila, paʻa a paʻa ka hale a ʻaʻole maʻalahi i ka ʻino.
6. Ke kū'ē i ka hopena kiʻekiʻe: Hanaʻia ka paipu grouting e kaʻenehana kūikawā, he paʻa paʻa a paʻa ka hana aʻaʻole hiki ke hoʻololi a maʻalahi.
7. Hana maʻalahi a maʻalahi: ʻAʻole kiʻekiʻe ka pololei o ka hana ʻana o ka paipu grouting, maʻalahi ke hoʻouka, a maʻalahi ka hana a me ka wikiwiki.
