I-HDPE biaxial geogrid yenziwe ngezinto zepolymer zepolyethylene yoxinaniso oluphezulu. Ikhutshelwa kwiphepha ize ibethelelwe kwipatheni yemesh eqhelekileyo, emva koko yolulelwe kwigridi yezalathiso zelongitudinal kunye nezinqamlezayo. I-polymer ephezulu ye-geogrid yeplastiki icwangciswe ngendlela yokufudumala kunye nokwelula inkqubo yokuvelisa, eyomeleza amandla okubopha phakathi kwamatyathanga eemolekyuli ngoko kwandisa amandla egridi.
