Description

Introduction

Geogrid composite is a composite of fiberglass geogrid, polyester geogrid and plastic geogrid combined with non-woven geotextile or fabric through adhesive and hot melting methods. The non woven geotextile surface is rough and not easy to slide during the construction. It enables the reinforced geogrid composite stay smooth in the process of paving. It is a kind of innovative composite geosynthetic materials, which organic combining the excellent performance of geogrid and geotextile. This product can be designed according to actual requirement.
Besides, we can also sew the geogrid and geotextile together which is more stable structure under outside force.

Applications

Normally, Geogrid Composite with Geotextile is widely used at home and abroad because it is cheaper compared with other kind geocomposite.
1. Used in surface reinforcement of highway, railway and airport road;
2. Used for the maintaining, re-construction and broaden of the old road surface
3. Used for reinforcement of irrigation channels and river dams.
4. Used to strengthen bridge connecting surface.
