Uni-drection geotechnical grid of plastic is produced from high density polyethylene(HDPE). It is made by pressed, punched, and stretched. Has high single- strength, good creep resistance, and stable chemical nature.Much better than the traditional or existing reinforced materials, it is a very good reinforced composite materials.
Product Features:
High single- strength and endurance, good creep resistance, and stable chemical nature
Application Field:
It mainly used in the construction of roads, railways and rivers, lakes and along the coast of the reinforced retaining wall,dam, bridge, steep slopes and other projects geocell.
1 Prevent roadbed distortion and crack caused the loss of roadbed materials;
2 Increase the self-supporting property of fill behind retaining wall, decrease the earth pressure of retaining wall, save cost,increase service life and reduce maintenance expense;
3 Enhance roadbed and effectively diffuse its load to improve its stability and bearing capacity and increase service life;
4 Simple and rapid construction will greatly reduce the construction cost.
