Uniaxial yas geogrid, ua los ntawm siab molecular polymer ntawm polypropylene, yog extruded rau hauv daim ntawv thiab ces xuas nrig ntaus rau hauv ib txwm mesh qauv thiab thaum kawg stretched nyob rau hauv lub transverse kev taw qhia. Qhov kev tsim khoom no tuaj yeem ua kom muaj kev ncaj ncees ntawm cov geogrid. Cov khoom siv PP yog qhov taw qhia zoo heev thiab tiv taus elongation thaum raug hnyav hnyav rau lub sijhawm ntev.
