Description

Introduction

Biaxially stretched plastic geogrid is made of polypropylene (PP) or polyethylene (PE) as raw materials, extruded through plasticization, punching, heating, longitudinal stretching, and transverse stretching. Geogrids have high tensile strength in both longitudinal and transverse directions, and this structure can provide an ideal chain system for more effective force bearing and diffusion in soil, suitable for large-area permanent bearing foundation reinforcement.

Applications

Suitable for reinforcement of various embankments and roadbeds, slope protection, tunnel wall reinforcement, and permanent bearing foundation reinforcement for large airports, parking lots, docks and freight yards.
1. Increase the bearing capacity of the road foundation and extend its service life.
2. Prevent road (ground) collapse or cracking, and maintain a beautiful and tidy ground.
3. Convenient construction, time-saving, labor-saving, shortened construction period, and reduced maintenance costs.
4. Prevent cracks in culverts.
5. Enhance soil slopes to prevent soil erosion.
6. Reduce the thickness of the cushion layer and save costs.
7. Support the stability and greening environment of the slope grass planting mat.
8. Can replace metal mesh and be used for false roof mesh in coal mines underground.
