PP Biaxial Geo-grid

Availability:
Quantity:

The main function of the Geo-grid for ground improvement will be increasing the reinforcement of the ground, and reduce the different settlement of the ground. The raw material of the biaxial geo-grid will be the PP,

 

Application:


PP Biaxial geo-grid can be used to enhancement of permanent bearable soft including roads and railways embankment, slopes, tunnel, airfields, parks, docks and ground which cargo lays on.

 

Performance:


1.Enhance the bearing capacity of road foundation and extend the duration of roads.

2.Prevent road surface from collapse, crack and being dirty.

3.Be convenient for construction, time saving and cut down the cost of maintenance.

4.Prevent tunnel from crack occurring.

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 fire-retardant and anti-statics.

No.
