Biaxial geogrid is a type of geogrids. It is made from high polymer. Biaxial geogrid has high strength in both longitudinal and transverse direction. It is made through the process of extruding, sheet forming, punching and stretching. Biaxial geogrid has good bearing capacity. It can enhance soil structure and prevent soil erosion. This product is often used to prevent the road from reflective and fatigue cracking. Biaxial geogrid can effectively improve the long term durability of subgrade and greatly reduces road maintenance costs. Biaxial geogrid has good resistance to long term degradation. It is suitable for various applications, such as embankment reinforcement, wall reinforcement, soil stabilization, slope protection and other permanent load bearing foundation reinforcement.
PP Bi-axial Geogrid for Road (ground) Base Description：
PP Bi-axial Geogrid is manufactured from Polypropylene. It is produced through the process of extruding, punching, heating, longitudinal stretching and transverse stretching.
PP Bi-axial Geogrid for Road (ground) Base Features：
1. High tension resistance, high plane torsion resistance modulus, good creep resistance and stable
Chemical nature.
2. High mechanic damage resistance and durability and large friction factor with sandy stone.
3. It can improve bearing force of foundation (normal improvement of above 40%) and increase diffusion angle（average increase to 50 degrees from 38 degrees).
4. Under the function of shaft times with same load, it can decrease 30%-40% of filling thickness for reaching same effect, when technical grid reinforcement is used, road bed with same thickness can bear more 3-5 times.
