Biaxial Plastic Geogrid For Tunnel Culvert Crack Resistance
Product Introduction
Bidirectional plastic geogates are high performance geosynthetics made of high molecular polymers and formed by stretching through a specific process.
Product Property
1. High strength: High tensile strength both longitudinally and laterally.
2. Low elongation: Polymer molecules rearrange during the heating extension process, strengthening the bond between molecular chains.
3. Durability: After adding anti-aging materials such as carbon black, it has good acid resistance, alkali resistance, corrosion resistance and anti-aging properties.
4. Simple construction: easy to transport and construction, no special equipment is required.
Product Application
1. Subgrade reinforcement: increase subgrade bearing capacity, extend service life, prevent pavement collapse or cracks.
2. Slope protection: enhance slope stability and prevent soil erosion.
3. Foundation reinforcement: Suitable for embankment, subgrade, large airport, parking lot, dock freight yard and other permanent load foundation reinforcement.
4. Culverts and tunnels: Prevent cracks in culverts and tunnels.
5. Coal mine underground support: can replace metal mesh, used for coal mine underground false top net.
