Geogrid is widely used in reinforcing soft groundwork, high road mound, erect quay, and road surface etc with excellent armored performance, which has much thing to do with the constructing process and techniques.The constructing means are as followed:
　　I、 Armored groundwork
　　Techniques & spec
　　Raft-cushion style：spread grid on the soft groundwork when the field is wide and flat, basal slope does not need washing and engineering vehicles can not directly walk on it, to shape a cushion. The cushion is 0.5-1.0m thick and there are 1-3 layers of geogrid.
　　Bedding style：in case that the building has high requirements on sedimentation and distortion, or there is a layer of geologic duricrust on the earth's surface, spread grid armored groundwork in hidden bedding. The bedding is 0.5-1.0m and there are 1-3 layers of geogrid.
　　Bearing style：for the important buiding and hi-stress base, spread the grid on the double base with pickets or minesto increase the bearing capacity and decrease sedimentation.
　　Constructing process
E.g. bedding: excavate bedding——spread geogrid—join & rivet geogrid—backfill soil—flatten—grind & press—then go back to step 3 (spread geogrid) till to the required height—end
　　II、 Techniques & spec
　　Claybank should be built on the steady bedding. If there is limits on the building site and steeper claybank is needed, spread geogrid along claybank.
　　Type & structure
　　Slope style：when claybank is not very high（less than 8M），grade is small（1：1），side slope can be changed into incline slope. Spread the geogrid along the slope. Its level length can be equal or not equal, depending on the design. Length is about 2-3m. Longitudinal space between grid layers is 0 for equal length and 3-0, 5m for equal length.
　　Constructing process:Level up the sloping field—stack sandbag or make mould on the surface—spread geogrid—joint & rivet geogrid—filling soil inside the mould—fold to slope surface and rivet it—filling & grinding—filling the upper layer—remove the nether mould—then go back to step 2 (stack sandbag or make mould on the surface) till to the required height—surface fence—end

　　III、 Armored road surface
　　Making use of compartmentation and side restriction to reduce crack on the surface, decrease track trail, prolong the maintenance period, thin the grass roots & road surface, etc.
Laying it on the surface or on the bottom according to different requirements.
