Polyester Geogrid
Introduction:
High strength warp knitted polyester geogrid is a kind of new high quality base maerial reinforcing the roadbed.It uses high strength polyester as its raw material and then warp knitted directionally and coated with special glue.
Features:
The warp knitted polyester geogrid has the characteristics of high intension, low elongational ratio, erosion-resistant, aging-resistant, high occlusive force with soil or gravel, light weight, water drainage and so on.
Function:
1. the soft soil roadbeds of road, railway and other municipal roads are reinfoced which can effectively improve the strength of subgrade, delaying reflection cracks in the road;
2. Reinforcement, segregation of the dam and river in water conservancy project reinforce the soft soil base, strengthen their protection and improve the bearing capacity and stability of the foundation;
3. Reinforcing the embankment slope, retaining walls reinforced to enhance the overall strength.
