Basalt Geogrid
Uniaxial Geogrid

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

  • High tension resistance, high plane torsion resistance modulus, good creep resistance and stable Chemical nature.
  • High mechanic damage resistance and durability and large friction factor with sandy stone.
  • It can improve bearing force of foundation (normal improvement of above 40%) and increase diffusion angle(average increase to 50 degrees from 38 degrees)
  • 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.

PP Bi-axial Geogrid for Road (ground) Base Application

  • Reinforcement of road beds of various highways, railways and airports.
  • Reinforcement of permanent bearing road beds of large parking area and dock goods yard.
  • Slope protection and culvert reinforcement of railway and highway.
  • Secondary reinforcement of soil slope after uni-axial tension technical grid reinforcement and further reinforcement of soil slope so as to avoid soil erosion.
  • Reinforcement of mile and gallery.
