HDPE biaxial geogrid ikozwe mubintu bya polymer bya polyethylene yuzuye. Isohora mu rupapuro hanyuma igakubitwa inshusho ya mesh isanzwe, hanyuma ikaramburwa muri gride mu burebure no mu cyerekezo. Polimeri ndende ya plastiki geogrid itunganijwe muburyo bwo gushyushya no kurambura inganda, bishimangira imbaraga zihuza iminyururu ya molekile bityo byongera imbaraga za gride.
