Plastic geogrid 

Plastic geogrid Introduction

Appearance of bidirectional tension plastic geotechnical grid is grid shape structure with near square. It uses polypropylene and high-density polyethlene as main raw materials, is pressed into plate by melting extrusion and formed by punching, heating, vertical and horizontal directional tension.

Plastic geogrid features

• High tension resistance, high plane torsion resistance modulus, good creep resistance and stable chemical nature.
• High mechanic damage resistance and durability and large friction factor with sandy stone.
• It can improve bearing force of foundation(normal improvement of above 40%)and increase diffusion angle (average increase to 50 degrees from 38 degrees).
• Under the function of shaft times with same load, it can decrease 30%-40%of filling thickness for reaching same effect;when geotechnical grid reinforcement is used, road bed with same thickness can bear more 3-5 times.

Plastic geogrid Application range

• Reinforcement of road beds of various highways, railways and airports
• Reinforcement of permanent bearing road beds of large parking area and dock goods yard.
• Slope protection and culvert reinforcement of railway and highway.
• Secondary reinforcement of soil slope after unidirectional tension geotechnical grid reinforcement and further reinforcement of soil slope so as to avoid soil ersion.
• Reinforcement of mile and gallery.

Plastic geogrid Packaging and storage

Biaxial Geogrid, the length of the product roll is decided by the construction request. The rolls are to be horizontally placed and not more than 6 layers high.

Unless otherwise specified, the production should be stored in a non-corrosive gas, non-dust, well-ventilated, dry and rainproof area

It is recommended that the room temperature should be maintained below 35°C,and humidity should be always maintained below 65%
