In road construction, PP geogrids can be used for roadbed reinforcement, pavement crack prevention, and other aspects to improve the bearing capacity and service life of roads. It can effectively disperse and withstand vehicle loads, reduce road settlement and deformation. In water conservancy facilities such as embankments and reservoirs, PP geogrids can be used to enhance the stability of soil, prevent soil erosion, and ensure engineering safety. Its corrosion resistance and aging resistance also enable the grille to be used in underwater environments for a long time without being affected.
