We, Shanghai Yingfan Engineering Material Co., Ltd., is a HDPE biaxial geogrid and other geosynthetics supplier in China. The soil body strength and deformation characteristics can be enhanced and improved after the reinforcement materials are mixed or laid. Geogrid is a quite important part of the reinforcement material family. HDPE biaxial geogrid can be defined as plastic stretching geogrid, which can be classified from woven PET geogrid, woven glass fiber geogrid, and others.

HDPE Biaxial Geogrid Introduction

HDPE biaxial geogrid is manufactured from high‑density polyethylene polymer. Raw material is extruded into sheets, punched to form regular mesh holes, then stretched longitudinally and transversely to form stable grid structure.

During thermal stretching production, polymer molecules are oriented orderly, enhancing molecular‑chain binding force and improving overall grid strength. Its core function is soil reinforcement.

Large apertures between longitudinal and transverse ribs allow soil interlocking through geogrid layers. Soil particles lock inside openings, bear against transverse ribs and transfer loads to longitudinal ribs through firm junction connections, realizing reliable mechanical anchoring effect.

Soil reinforcement plays a vital role in foundation construction. Soil features good compression and shear resistance but poor tensile capacity. Embedding geogrid inside soil greatly improves tensile‑shear performance and keeps soil particles interlocked. Our geogrids bring reliable engineering performance.
