Polyester GeoGrid
Polyester Geogrid PVC Coated
Product introduction:
The warp knitting polyester geogrid selects industrial high-strength, anti-embrittlement, low shrinkage polyester yarn as raw material, adopts the warp knitting oriented structure, latitude and longitude in the fabric to the yarn to each other without bending state,
Intersection sewn up with high strength fiber filament bundle, forming strong combining site, and through high-quality oil or water based PVC coating processing and form the plane shape of material, fully Play its mechanical properties.
Features:
The warp knitting polyester geogrid has high strength, high modulus, low creep, anti-aging, brittle crack resistance, high tensile strength, tensile strength, with the soil crushed stone binding force strong and
May pre-design many kinds of characteristics.
Application:
1, highway and repair roads, railway, airport, soft subgrade.
2, embankment slope strengthening solid, the Banks of the river.
3, all kinds of solid foundation.
4, road and bridge pavement.
- For Bi-axial type:
