Woven coated biaxial polyester geogrids

Product Introduction:

1. High tensile strength;
2. Low elongation ratio;
3. Anti-erosion and anti-aging;
4. Strong combination with gravel and soil;
5. Being light and has drainage effect.

Product Application:

1. It mainly applied on strengthening soft ground of road, railway and municipal road. It can improve the strength of foundation effectively, and prevent road cracking. 

2. Polyester geogrid is widely used on enforcement and isolation of damsand rivers in hydraulic projects. It can strengthen the soft soil foundation, enhance the protective ability and improve the bearing capacity and stability of foundation. 

3. Polyester geogrid is applied on the enforcement of embankement, slope and retaining wall to strengthen the overall intensity. It’s used on the enhancement of soft soil of road, railway and hydraulic projects.

4. Warp knitted polyester geogrid is used on railway ballast protection. Because of the train vibration and weather factors, the ballast will lose greatly. Wrapping ballast with geogrid can prevent ballast loss and improve the stability of foundation. 

5. The product is used on railway retaining wall, for example the goods pallet to prolong the lifespan and reduce maintenance costs. 

6. It’s applied on enforcement of retaining wall: highway and vertical wall with polyester geogrid could improve the bearing capacity of retaining wall. 

7. The abutment foundation is easy to sink. Applying polyester geogrid under abutment foundation can improve the bearing capacity stability. 

Construction Method:

The road should be levelled and cleaned before construction at first. Then the geogrid should be laid on the coarse stone of asphalt layer. If customers use normal geogrid, they need specific steel-nail to fix geogrid joints. The intersections should be bigger then the size: 5cm on the horizontal direction and 10cm on the vertical direction. It’s better to spill the least asphalt adhesive oil. If customers use self-adhesive geogrid, they can pave and compact asphalt mixture after crushing of tyre-wheels roller, and there’s no need to fix with specific steel-nails.
