Description

Introduction

Biaxially stretched plastic geogrid is made of polypropylene (PP) or polyethylene (PE) as uncooked materials, extruded thru plasticization, punching, heating, longitudinal stretching, and transverse stretching. Geogrids have excessive tensile electricity in each longitudinal and transverse directions, and this shape can furnish an best chain device for greater high quality pressure bearing and diffusion in soil, appropriate for large-area everlasting bearing basis reinforcement.

Applications

Suitable for reinforcement of a number of embankments and roadbeds, slope protection, tunnel wall reinforcement, and everlasting bearing basis reinforcement for massive airports, parking lots, docks and freight yards.
1. Increase the bearing ability of the avenue basis and lengthen its provider life.
2. Prevent street (ground) cave in or cracking, and preserve a stunning and tidy ground.
3. Convenient construction, time-saving, labor-saving, shortened development period, and decreased upkeep costs.
4. Prevent cracks in culverts.
5. Enhance soil slopes to stop soil erosion.
6. Reduce the thickness of the cushion layer and shop costs.
7. Support the steadiness and greening surroundings of the slope grass planting mat.
8. Can exchange metallic mesh and be used for false roof mesh in coal mines underground.
