Introduction
The outlook of the biaxial geogrid is network structure like a square. It uses polyester as its raw material and made of high molecular polymer through extrusion, formed and punched before longitudinally and laterally stretched. This kind of material has high tensile longitudinally and horizontally, which can be used to reinforce the basement.
Function
1. It can be applied in all kinds of roads, railways, airports to enhance the roadbed;
2. It can be applied in a large car park and terminal freight yard, etc. to strenghten the foundations of a permanent load;
3. It can be applied in rail, road slope's protection;
4. It can be applied to enhance the culvert;
5. It can be applied as a secondary enhancement after the uniaxial Geogrid soil enhancement, further enhance the soil, prevent soil erosion;
6. It can be applied in mining, tunnel reinforcement.
