Application:

PP biaxial geogrids can be used to enhancement of permanent bearable soft including highway and railways embankment, slopes, tunnel, airport, parking lots, loaded pier and ground and their main usage are as follows:

1. enhance the bearing capacity fo road foundation and extend the duration of highway.

2. prevent highway surface from collapse, crack and being dirty.

3. be convenient for construction timesaving and cut down the cost of maintenance.

4. prevent tunel from crack occuring

5. further solidity slopes to proof water and soil from losses

6. reduce the surface thickness of the ground.

7. consolidate the net for growing grass on the slopes

    so as to stabilization surrounding virescence.

8. be used for artificial top net of mines instead of metal ones.

    It is of flame retardant and antistatics.
