Nā Geotextiles ulana ikaika kiʻekiʻe me ka paʻa maikaʻi
Hana ʻia ka geotextile me ka polypropylene, polypropylene a me ka polyethylene nā ʻili palahalaha ma ke ʻano he mea maka, a ʻo ia ka liʻiliʻi o ʻelua pūʻulu o nā ʻili like (a i ʻole nā wili palahalaha).Ua kapa ʻia kekahi hui ma ka ʻaoʻao lōʻihi o ka ulana (ke ala e hele ai ka lole).Hoʻopiliʻia ka'ōniʻoniʻo a me ka ulana i keʻano o ka lole me nā mea ulana likeʻole a me nā kaʻina hana, hiki ke ulanaʻia i loko o nā mānoanoa likeʻole a me nā densities e like me nā pae noi likeʻole, me ke kūpaʻa maikaʻi.

1. Hiki ke ʻoki ʻia nā geotextiles me ka pahi geotextile (hook knife).Inā ʻoki ʻia ma ka pūnaewele, pono e lawe ʻia nā hana pale kūikawā no nā mea ʻē aʻe e pale ai i ka pōʻino pono ʻole i hana ʻia e ka ʻoki ʻana i nā geotextiles;
2. I ka manawa like me ka waiho ʻana o ka geotextile, pono e hana ʻia nā hana kūpono a pau e pale ai i ka pōʻino o ka mea ma lalo;
3. I ka hoʻomoe ʻana i nā geotextiles, e makaʻala ʻaʻole e ʻae i nā mea ʻē aʻe e like me nā pōhaku, ka lepo nui a i ʻole ka lepo e hōʻino ai i ka geotextile, poloka i nā kahawai a i ʻole nā kānana, a i ʻole e paʻakikī i nā pilina ma hope;

5. Pono nā pilina o nā geotextiles e hahai i kēia mau lula: Ma lalo o nā kūlana maʻamau, ʻaʻole e hoʻokuʻi ʻia ma ka pali (ʻaʻole e hui ʻia nā pilina me ka contour slope), koe wale nō kahi e hana ʻia ai ka hoʻoponopono.
6. Inā hoʻohana ʻia nā humuhumu, pono e hana ʻia nā humuhumu me ka mea like a ʻoi aku paha ma mua o nā mea geotextile, a pono e hana ʻia nā humuhumu me nā mea hiki ke pale i ka uv kemika.Pono ka ʻokoʻa kala ma waena o nā sutures a me nā geotextiles i mea e maʻalahi ai ka nānā ʻana.
7. Pono e mālama pono i ka wā e hoʻokomo ai i ʻole e komo ka ʻiliʻili mai ka lepo a i ʻole ka uhi ʻiliʻili i waenakonu o ka geotextile.
