Description

Introduction

Biaxial Plastic Geogrid for Construction
Geogrid is made of high polymer, which is extruded the thin sheet, then rushed the regular mesh and two ways extension. This material has a high tensile strength, so it can also provide the ideal force bear and spread of the interlock systems for the soil, suitable for large area permanent load-bearing of groundwork.

Biaxial geogrids have been utilized in pavement construction and soil stabilization projects throughout the worldwide.Biaxial Geogrid is Strata's innovative geogrid that is made from extruded polypropylene which provides superior stiffness, aperture stability and interlock capabilities for structural reinforcement of paved and unpaved roads.
