We, Shanghai Yingfan Engineering Material Co., Ltd., is one PP biaxial geogrid supplier, located in Shanghai city of China. Because the netting structure of such geogrid in the soil can produce embedded and interlock force, so the geogrid can stabilize the soil. More and more geogrids are having been used in reinforced soil walls and slopes. A lot of clients from our country and other countries buy PP biaxial geogrid to use them in a lot of reinforcement applications.

PP Biaxial Geogrid Introduction

Geogrid is a geosynthetic material for soil‑reinforcement purposes. Reinforcement is its primary function. For decades, biaxial geogrids have been widely adopted in pavement construction and soil‑stabilization projects worldwide. They are frequently used for retaining‑wall reinforcement, as well as sub‑base and sub‑soil reinforcement beneath roads and structures. Soil is weak under tension, while geogrids deliver outstanding tensile performance.

Our PP biaxial geogrid is manufactured by punching regular holes on polymer sheets and then stretching into grid structure.

PP biaxial geogrid features nearly equal tensile strength in both machine and cross directions. It spreads loads over wider areas and improves soil bearing capacity. It interlocks with aggregates to confine base layers and reinforce subgrade. For paved or unpaved roads, it reduces rutting and keeps aggregate thickness stable.

Lateral displacement of base‑course aggregates is one main failure mode for pavement structures. PP biaxial geogrid effectively restrains lateral spreading, improves structural performance and extends pavement service life. It can even reduce required aggregate thickness by up to 50%.
