Introduction

HDPE Uniaxial Geogrids arehigh strength polymer grid structures that form an extremely efficient reinforcing by performing as a network of distributed anchors within a soil matrix.

HDPE Uniaxial Geogrids are made by a process of extruding,punching,heating and longitudinal stretching.

HDPE Uniaxial Geogrids are made of  high density polyethylene and chemically insert,unaffected by the UV rays and fully resistant to aging in the soil environment.

Properties Of HDPE Uniaxial Geogrid

*Resistance to biological degradation or attack

*Chemical resistance

*Weathering resistance from UV degradation through incorporating additive of carbon black

*Resistance to environmental stress cracking

*High strength and smaller creep

*Improve the service life of the project

 Application Of HDPE Uniaxial Geogrid 

*Retaining walls/slopes of road and railway embankments, road shoulders, approaches, ramps, abutments, etc

*Water-facing structures of earth-rock dam, flood barrier, breakwater, cofferdam, river, reservoir regulation and protection works etc

*Site support structure of  water conservancy, electricity, mining, metallurgy, airports, warehouses, civil facilities etc

*Retaining walls of tailings treatment, reservoir, landfill, environmental protection construction and landslide control etc

*Suitable for all kinds of soil, save labor and time

*It’s simple and convenient to use,and reduce cost
