Description

Introduction

Composite geogrids are used for stabilize soils where a both reinforcing and separation between a granular base and very fine soil is required.
The geocomposite binds closely to the soil being reinforced, separates different soil types and provides an effective filter
action.

Composite geogrids are made by bonding a nonwoven geotextile to PP biaxial geogrid.
Composite geogrids have both a high tensile strength and modulus of elasticity, resist damage during installation, and weathering by the atmosphere.

Applications

Normally, Geogrid Composite with Geotextile is widely used at home and abroad because itis 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.
