Mabasiketi a Double Twisted Hexagonal Mesh Gabion and Mattresses akhala akugwiritsidwa ntchito padziko lonse lapansi posungira khoma, kukhazikika kwa malo otsetsereka, kuyanika kwa tchanelo, chitetezo cha rockfall ndi ntchito zina zambiri kwazaka zopitilira 100.Chifukwa cha kutsika mtengo kwanthawi yayitali njira zokhotakhota zapawiri zopindika ma mesh gabions zimapatsa ogwiritsa ntchito izi kugwiritsa ntchito kwawo kwafala ndi mabungwe ambiri aboma, ndi Private Land Developments etc… kuno ku United States.
Pamene kugwiritsiridwa ntchito kwa gabion kunkakula m'nyumba kufunikira kwa chikhalidwe chamakampani kunakhala kofunikira kuti zitsimikizire kusasinthasintha kwazinthu.Bungwe la AMERICAN SOCIETY OF MATERIALS AND TESTING lakhala likudziwika kuti limafunikira miyezo yapamwamba kwambiri komanso kuthandiza mafakitale kuti akhazikitse mulingo wamakampani pazinthu ndi zinthu zina.Bungwe la AMERICAN SOCIETY OF MATERIALS AND TESTING (ASTM) limasindikiza buku lachindunji lomwe limalemba chilichonse m'mawonekedwe ake onse.Chidziwitso chilichonse chazinthu zomwe zili m'buku la ASTM zimayikidwa nambala yotsimikizika kuti igwiritsidwe ntchito.Nambala yodziwika ya ASTM ya Double Twisted Hexagonal Mesh Gabions ndi ASTM A975-97.
Mtundu wonse wa ASTM A975-97 sunawonetsedwe kwathunthu.Zofunikira pakugwira ntchito kwa chinthu chomalizidwa komanso chidziwitso chazinthu zomwe zimayimiridwa.
