Papahele permeable kala-mālama i ke kaulike kaiaolaola ʻO ka papahele palekana kaiapuni permeable kala, i ʻike ʻia hoʻi he sima porous, ma ka ʻili o ka ʻāhui coarse i uhi ʻia me kahi papa lahilahi o ka paʻi sima, ka ʻāhui a me ka paʻi sima i hoʻopaʻa ʻia kekahi i kekahi e hana i kahi hoʻolaha like o nā pore.
ʻO ka mālama ʻana i ke kaulike kaiaola o ka papahele pale kaiapuni permeable kala, i ʻike ʻia hoʻi ʻo "porous concrete", ma o ka ʻili o ka aggregate coarse i uhi ʻia me kahi papa lahilahi o ka sima paʻi, aggregate a me ka sima paʻi i hoʻopaʻa ʻia kekahi i kekahi e hana i kahi hoʻolaha like o nā lua i loko o ka hale meli, no laila he permeability ea, permeability wai a me nā hiʻohiʻona māmā, e hāpai pono ana i ka hanana o ka waterlogging a hoʻopau pono i nā pōʻino o ka haumia kaiapuni e like me nā hui aila ma ka honua. He mea paving maikaʻi loa ia e mālama i ke kaulike kaiaola o ke kaiapuni. Hoʻohana ʻia ka papahele permeable kala i nā alanui, nā kahua lehulehu, nā wahi kaʻa ākea, nā alanui ma nā paka, nā alanui hele wāwae kalepa, nā alanui noho a me nā alanui pā hale kaiāulu a pēlā aku.
